The following is a list of former state routes in Pennsylvania. These roads are now either parts of other routes or no longer carry a traffic route number. This list also includes original routes of numbers that were decommissioned and later reactivated in other locations in which most of these are still active today.
The original Pennsylvania Route 3 was the designation for the William Penn Highway running from Hanover Township to Easton. After its decommissioning in 1930, PA 3 was renumbered in several areas to extend active routes, including US 22 from the WV/PA state line to Harrisburg, PA 60 from Robinson Township to Pittsburgh, US 322 from Harrisburg to Hershey, US 422 from Hershey to Wyomissing, US 422 Business from Wyomissing to Reading, US 222 Business from Reading to Laureldale, US 222 from Laureldale to Dorneyville (except the Kutztown and Trexlertown/Wescosville bypasses), and PA 222 from Dorneyville to Allentown.
PA 3 was reactivated in 1936 to its current alignment from West Chester to downtown Philadelphia.
The original Pennsylvania Route 10 was designated on the current segment of US 119 between Blairsville/Indiana County and DuBois/Clearfield County. The route number was reactivated in 1956 and applied to the route now aligned through Chester, Lancaster, and Berks Counties.
Pennsylvania Route 22 was a 60-mile-long (97 km) state highway that ran through Lehigh, Carbon, and Luzerne Counties. The southern terminus was at PA 3 in Allentown and the northern terminus was at PA 19 in Wilkes-Barre. The route was decommissioned in 1930 and renumbered as an alignment of US 309 which was decommissioned and changed in February 1968 to its current designation of PA 309.
Pennsylvania Route 43 was reactivated in 1952 and reassigned along the Schuylkill Expressway (which was already designated as then-I-80S, thus forming a concurrency) from King Of Prussia (at the Pennsylvania Turnpike) to the PA/NJ state line midway across the Walt Whitman Bridge. In 1964, both designations were dropped and the expressway was renumbered as an extension of I-76.
The original Pennsylvania Route 65 was designated on the current U.S. 62 segment from the OH/PA state line outside of Sharon/Mercer County to PA 8 in Franklin/Venango County. PA 65 was reactivated and assigned in 1961 to its current Allegheny/Beaver/Lawrence County alignment.
PA 71 had an alternate route, PA 71 Alternate, which was assigned in 1957 as the temporary designation for the four-lane divided highway between PA 519 near Washington and New Stanton that was known as the "Express Highway"; this road would be designated as I-70S (now I-70) following the completion of additional connecting roads in the Interstate Highway System.
In 1948, a drive-in theater was built on PA 71 in Rostraver Township, just off of I-70, and was named after its route: Super 71 Drive-In. This name was kept throughout its entire existence (1948-1995), even after the stretch of PA 71 it was located on was decommissioned and renumbered PA 201.
The second Pennsylvania Route 76 designation ran from the Maryland state line near Warfordsburg/Fulton County to U.S. 322 in Reedsville/Mifflin County. PA 76 was decommissioned in 1964 and reassigned as current PA 655. SR 0076 was later assigned to its current designation on Interstate 76.
The route was deleted in 1961 and replaced by Pennsylvania Route 380 from US 22/US 30 to Dallas Avenue in Pittsburgh, Pennsylvania Route 8 from Dallas Avenue to US 22 exit 8 in Wilkinsburg, US 22 from Wilkinsburg to Pennsylvania Route 286 and PA 286 from US 22 to US 219. This designation change was made to reduce the number of concurrent routes in Pittsburgh. The changes took effect a few months later and signs were changed by spring 1961.
Pennsylvania Route 81 was the unsigned designation for the entire Pennsylvania segment of US 40 (National Road) between 1926 and 1930. In 1958, SR 0081 was assigned upon beginning of the construction of Interstate 81.
The original Pennsylvania Route 118 was located in Beaver County and ran from Pine Street in Hookstown to PA 18 (Frankfort Road) near Shippingport. The route was designated in 1928 and decommissioned in 1946. The old segment from Pine Street to Cooks Ferry became a realignment of PA 168 in 1951. Cooks Ferry was used to cross the Ohio River and join PA 168 northbound in Midland until 1964 when it was replaced by the Shippingport Bridge.
PA 118 was reactivated to its current northeastern Pennsylvania location in 1967.
The original Pennsylvania Route 121 ran entirely in Greene County from the WV/PA state line near Point Marion to PA 21 in East Waynesburg. The route was decommissioned in 1950 and the number was reactivated in 1961 to its current location in Allegheny County.
Pennsylvania Route 123 was an 4-mile-long (6.4 km) state highway located in Montgomery County. The southern terminus was at PA 23 in Gulph and the northern terminus was at US 202 in Bridgeport. PA 123 was decommissioned in 1946 and was not renumbered.
Pennsylvania Route 126 was a 23-mile-long (37 km) state highway located in Fulton and Bedford Counties, running from US 522 in Warfordsburg to US 30 in Breezewood. In 1963, PA 126 was moved to run concurrently with the recently opened segment of I-70 that paralleled the old road. The following year, I-70 became the sole designation as PA 126 was decommissioned.
Pennsylvania Route 129 in Delaware County was a 5-mile (8.0 km) route, running from US 202 in Markham to PA 352 in Gradyville. It was decommissioned in 1946 and not renumbered or reassigned to any other routes.
Pennsylvania Route 163 is the former designation for Edge Hill Road and Terwood Road, running from PA 63 in Willow Grove east to PA 63 in Bethayres in Montgomery County. The route was first designated in 1928 to run from PA 73 in Philadelphia north to PA 63/PA 232 in Bethayres. By 1940, PA 163 was redesignated onto Edge Hill and Terwood roads, with PA 232 extended south along the former alignment between Philadelphia and Bethayres. The PA 163 designation was removed in the 1940s.
The original Pennsylvania Route 171 was situated along Fells Church Road, running from PA 51 to former PA 71 (now PA 201) in Rostraver Township, Westmoreland County. PA 171 was decommissioned in 1946 and reactivated in 1961 to its current alignment in Northeastern Pennsylvania.
The original Pennsylvania Route 181 ran for approximately 3 miles along the Somerset County side of the Youghiogheny River from the MD/PA state line to U.S. 40 in Addison Township. In 1944, the Youghiogheny River Lake by formed by damming its river upstream in nearby Confluence. This widened the river from Confluence to the state line, sinking the designated PA 181 road in the process and calling for its decommissioning by 1946. PA 181 was reactivated and assigned to its current York County alignment in 1961.
In 1936, the segment of PA 180 in Allegheny County from its western terminus at PA 80 (now PA 380) in Penn Hills to Tri-Boro Avenue (now Tri-Boro Expressway) in Turtle Creek was renumbered Pennsylvania Route 186. Five years later, PA 186 was decommissioned and renumbered back to PA 180.
Pennsylvania Route 189 in Erie County (a/k/a Hare Creek Road) was the designation for what became an alignment of PA 426 (southern segment) from U.S. 6 in Corry to the PA/NY state line in Wayne Township.
The original Pennsylvania Route 199 in Erie County was one of the shortest PA routes commissioned. It ran for just under a mile along the segment of Asbury Road from U.S. 20 to the intersection of PA 5 and Alternate PA 5 in Millcreek Township, just outside Erie. This was decommissioned in 1964; ten years later, PA 199 was reactivated and reassigned to its current Bradford County alignment.
The original Pennsylvania Route 215 ran from PA 940 in Tobyhanna Township/Monroe County to PA 315 in Dupont/Luzerne County. PA 215 was decommissioned in 1946 and reactivated in 1962 to its current alignment in Erie County.
The original Pennsylvania Route 218 was a short-lived Lawrence/Mercer County route that ran from the intersection of PA 18 and PA 318 West Middlesex to PA 18 in New Wilmington. Less than a year after its commissioning, the entire route was decommissioned and renumbered as PA 278 (described below). PA 218 was reactivated in 1936 to its current 13-mile alignment in Greene County.
Before the current Pennsylvania Route 221 was commissioned in 1936, a short 1 1/2 mile segment between then-PA 121 and PA 88 in Dunkard Township/Greene County was originally assigned that route number as early as 1930. From 1936 to the original route's decommissioning in 1946, there were two separate PA 221 designations with a gap of 21 miles between them. The decommissioned segment is now known as Holbert Stretch Road.
Pennsylvania Route 266 started out as a 5 1/2 mile route in Fayette County, running from PA 166 near New Geneva to U.S. 119 in Smithfield. In 1950, the original PA Route 121 across the Monongahela River in Greene County was decommissioned and the segment from PA 88 in Greensboro to PA 21 in East Waynesburg was renumbered PA 266. As a result, a ferry was provided as a connector for the two designations across the Monongahela between Greensboro and New Geneva. PA 266 was decommissioned in 1955 and the route was not renumbered or realigned with any other active routes.
Pennsylvania Route 278 was originally designated in 1928 as PA 218, a 9-mile "L-shaped" Mercer/Lawrence County route that ran from the intersection of PA 18 and PA 318 in West Middlesex to PA 18 in New Wilmington. Shortly after its renumbering to PA 278 the following year, the eastern terminus was extended to U.S. 19 in Washington Township. In 1936, the western terminus was moved to U.S. 422 in Pulaski Township near the PA/OH state line, thus situating the route entirely in Lawrence County; the former segment from West Middlesex from Pulaski Township was renumbered as an alignment of PA 551. In 1959, PA 278 was decommissioned and the segment from its western terminus to PA 168 was renumbered as an realignment of current PA 208. The remaining eastern segment from PA 168 to U.S. 19 was not renumbered.
Pennsylvania Route 280 in Allegheny County ran entirely along Rodi Road from Thompson Run Road (formerly PA 503) in Wilkins Township to its northern terminus at former PA 80 (now PA 380) in Penn Hills from 1928 to its decommissioning in 1946. In 1963, the 2.10-mile segment from US 22 Business in Churchill to said northern terminus was assigned its current route, PA 791.
Pennsylvania Route 319 in Fayette County ran from the WV/PA state line in Lake Lynn to U.S. 40 in Hopwood. It was decommissioned in 1946 and the southern portion was reassigned in 1967 as its current designation of PA 857.
Pennsylvania Route 336 ran from PA 286 in Glen Campbell/Indiana County to former PA 236 near Rossiter/Jefferson County. It was one of the longer lasting former routes, having been decommissioned in 1984 and separated into four quadrant state routes.
Pennsylvania Route 359 in Armstrong County ran from PA 56 in Kiskiminetas Township to PA 66 in Manor Township. It was one of the longer lasting former routes, having been decommissioned in 1981 and reassigned as SR 2025.
Pennsylvania Route 451 ran along the northern edge of Beaver Country from the then-eastern terminus of PA 351 to PA 18 in Koppel. In 1936, PA 351 extended its eastern segment with the decommissioning of PA 451 and the opening of the last segment from Koppel to its current terminus at PA 65/PA 288 in Ellwood City.
Pennsylvania Route 458 in Mercer County started at the intersection of PA 322 and PA 58's then-western terminus in Jamestown (near the Mercer/Crawford County line) and ran for three miles westbound to the Ohio/Pennsylvania state line in Greene Township. In 1946, PA 458 was decommissioned and became the last western segment of PA 58.
Pennsylvania Route 466 was a Westmoreland County route that ran from PA 56/PA 356 in Allegheny Township to PA 66 in Washington Township. It was decommissioned and renumbered in 1946, extending PA 356 to its current southern terminus.
Pennsylvania Route 503 was a 6-mile Allegheny County route that ran from former PA 180 (which became concurrent with PA 993 in 1941 and is now solely PA 130) in Turtle Creek to former PA 80 (now PA 380) in Penn Hills.
Pennsylvania Route 527 in Forest County was first signed in Pleasantville. Two years later, it was moved east near the Allegheny River, running along Preacher Hill Road from McArthur Run Road to PA 127 (Fleming Hill Road) in Harmony Township.
Pennsylvania Route 566 ran through Armstrong County from the intersection of the PA 56/PA 66 concurrency/split in North Vandergrift to PA 66 in Bethel Township. In 1938, PA 566 was replaced with its current designation of Alternate PA 66 which was then extended into Westmoreland County to the current southern terminus at its parent route in Washington Township.
Pennsylvania Route 602 in Susquehanna County ran from U.S. 11 in Hallstead to the PA/NY state line six miles north. This was renumbered in 1946 as a realignment of PA 70. When PA 70 was renumbered PA 171 in 1961, the northern terminus was truncated from the state line to its current location at I-81 in Great Bend. The decommissioned segment, which was the former PA 602, was renumbered as Quadrant SR 1033.
Pennsylvania Route 651 in Beaver County started at the OH/PA state line in Darlington Township and ran eastbound through Darlington Borough, back into the township of the same name, Big Beaver and to its eastern terminus at PA 18 in Homewood.
In 1936, PA 168 was extended northbound from its previous terminus in Beaver. As a result, 1.2 miles of its new designation ran concurrently with PA 651 from Market Street in Darlington Borough to Ashwood Road in Big Beaver.
Pennsylvania Route 680 was the original designation of current PA 217. PA 680 originally terminated southbound at U.S. 22 in Blairsville/Indiana County; it was extended in 1936 to its current southern terminus at U.S. 30 on the border of Unity and Derry Townships in Westmoreland County. In 1961, PA 680 was renumbered as PA 217 to avoid numerical duplication with I-680 in Philadelphia. Despite this, I-680 was changed to I-676 in 1964 when its parent I-80S (Pennsylvania Turnpike) was changed to I-76.
Running entirely in Westmoreland County, Pennsylvania Route 766 was designated on the entire stretch of Oakford Park Road. Its southern terminus was at former PA 180 (now PA 130, Harrison Avenue) in Jeannette and its northern terminus at former PA 66 (now Business PA 66, Sheridan Road) in Greensburg.
Pennsylvania Route 780 was one of the few state numbers to have two active routes in two different counties at the same time. The original PA 780 was commissioned in 1930; it was located in Clinton County and ran from a segment of U.S. 220 that was later "swapped" with parallel PA 64 in Lamar to PA 880 in Loganton. Six years later, PA 780's second (and currently active) designation was assigned in Westmoreland County. After the original PA 780 was decommissioned in 1967, the segment from the eastern terminus at North Mill Road to Narrows Road was renumbered as a realignment of PA 880.
Pennsylvania Route 802 in Allegheny County ran from the former concurrency of PA 28/PA 519 (now PA 50, Washington Avenue) in Heidelberg to the former multiple concurrency of US 19/US 22/US 30/PA 28/PA 51/PA 88 (now PA 60, South Main Street) in the West End neighborhood of Pittsburgh. In 1961, with the opening of a new interchange to the Penn Lincoln Parkway in Green Tree, the former PA 802 segment from the intersection of Greentree and Cochran Roads to the intersection of Greentree Road and Mansfield Avenue was reassigned as a part of the new PA 121, having been decommissioned from its original route in 1950.
Pennsylvania Route 805 in Allegheny County was a "horseshoe" route that began and ended at two different points of former PA 8/PA 28 (now solely PA 28). From the northern terminus, PA 805 ran up through Millvale, Shaler Township and Ross Township, then wound back down through the Pittsburgh neighborhoods of Summer Hill, Northview Heights, Spring Hill/City View and East Allegheny to its southern terminus.
Pennsylvania Route 836 in Allegheny County was a "U-shaped" route located in Pittsburgh's North Hills. Beginning on Saxonburg Boulevard at PA 910 in Indiana Township, the route ran south through Fox Chapel, O'Hara Township, Shaler Township and Etna. Crossing over PA 8 in Etna, PA 836 continued northbound back into Shaler Township and ran concurrently with Mount Royal Boulevard to its northern terminus at PA 8 in Hampton Township.
The original Pennsylvania Route 844 was located in Indiana County and ran from former PA 80 (now PA 286) to West Lebanon Road in Saltsburg. It was decommissioned in 1946 and the route number was reactivated to its current Washington County location in 1964.
Pennsylvania Route 856 (PA 856) was a state route that ran from PA 65 in Freedom in Beaver County southeast to another intersection with PA 65 in Emsworth in Allegheny County. PA 856 headed east from PA 65 in Freedom and had an intersection with PA 989 before it left Beaver County for Allegheny County. At this point, the route curved southeast and then south before it passed through Franklin Park. PA 856 continued south to its end at PA 65 in Emsworth.
The route was designated in 1928 to run from PA 857 (now PA 65) in Freedom east to Knob along an unpaved road. PA 856 was paved by 1930. In the 1930s, the route was extended from Knob southeast to PA 88 (now PA 65) in Emsworth, with a portion of road north of Emsworth replacing PA 989. PA 856 was decommissioned in 1976 due to the completion of the parallel I-79 in the area. The state continued to maintain the former alignment of PA 856. Two years after the route was decommissioned, local residents complained about lack of snow removal and felt that PennDOT had abandoned the road when they removed the PA 856 designation. However, the state reminded the residents that they still maintain the road and that snow removal along the former route was secondary to more important routes, in addition to suggesting local municipalities can take over snow removal.
PA Routes 881-886 were all situated throughout southeast Allegheny County. Only PA 885 remains active today.
Pennsylvania Route 881 began at the intersection of Walnut Street and Long Run Road in Versailles and ran northbound to U.S. 30 in East Pittsburgh. After PA 881 was decommissioned in 1946, nearby PA 148 was realigned to include two separate segments of the former route.
Pennsylvania Route 882 began at the intersection of Lovedale and Mill Hill Roads (which was the PA 884 junction at the time) in Lincoln and ran north along winding roads before entering Elizabeth Township and reaching the northern terminus at PA 48 as part of a five-way intersection before the Boston Bridge (PA 883 also terminated at this intersection from the south before its decommissioning in 1932).
Pennsylvania Route 883 was situated entirely in Elizabeth Township, beginning on Broadlawn Road at PA 48 and running northbound along Broadlawn, Greenock Buena Vista and Renzie Roads before terminating back onto PA 48 at a 5-way intersection before the Boston Bridge (PA 882 also terminated at this intersection from the west).
Pennsylvania Route 884 started on Long Hollow Road at a former segment of PA 31 (now PA 136) in Elizabeth Borough (right near the Allegheny/Westmoreland County border) and ran northbound to its terminus PA 51 in Elizabeth Borough.
Pennsylvania Route 886 began on Mill Hill Road at PA 48 and ran westbound, straddling along the border of Elizabeth Township and Lincoln before reaching the western terminus at then-PA 884 (McKeesport Road). In 1999, PA 86 in Crawford County was reassigned SR 0886 (but not as that route as the PA 86 signage has been kept intact) when Interstate 86 opened in Erie County and was given the SR 0086 designation.
Pennsylvania Route 894 (PA 894) in Dauphin County originally ran from former PA 43 (now U.S. 22) in Paxtonia to Linglestown, Pennsylvania. In 1936, PA 894's northern end was extended, terminating at PA 443 in Piketown.
Pennsylvania Route 905 (PA 905), situated in the southernmost area of Allegheny County, ran from a former alignment of PA 31 (now PA 136) in Forward Township to PA 51 in Elizabeth. PA 905 was first designated in 1928 as a short unpaved spur off PA 31 to the east of Monongahela. In 1930, the route was constructed as a concrete road serving as a shortcut between Monongahela and Elizabeth. The road connected farmland in Forward Township with Elizabeth and PA 31 and formed part of an outer beltline of Allegheny County. The PA 905 designation was removed in 1946.
Pennsylvania Route 908 (PA 894) in Allegheny County ran from Harmar to the northwestern corner of the county in Natrona Heights, beginning and ending at different points of a former (pre-Allegheny Valley Expressway) alignment of PA 28 (Freeport Road).
Pennsylvania Route 909 (PA 909) was a 6-mile state road that ran across and parallel to the Allegheny River through Oakmont, Plum, New Kensington and Lower Burrell, northeast of Pittsburgh. From its southern terminus at the Freeport Road (Old PA 28) end of the Hulton Bridge in Harmar/Allegheny County, PA 909 ran across the bridge along Hulton Road, Coxcomb Hill Road and Logan's Ferry Road and into Westmoreland County where the northern terminus at PA 366 straddles between New Kensington and Lower Burrell. Although officially decommissioned in 1946, a signpost at the intersection of Logan's Ferry and Coxcomb Hill Roads shows the latter road as ROUTE 909.
Two of the Allegheny County's Belt System routes run concurrently with this former route: : From the southern terminus at Freeport Road (Old PA 28) to the intersection of Hulton and Coxcomb Hill Roads : From the intersection of Coxcomb Hill and Logan's Ferry Roads to the northern terminus at PA 366.
Pennsylvania Route 918 in Bedford County first ran from the MD/PA state line to PA 326 in Southampton Township. In 1936, PA 918 was truncated down to 4 1/2 miles when it was "swapped" with the segment of PA 326 from Chaneysville to PA 26.
Pennsylvania Route 930 was first commissioned for 1 1/2 miles on Galilee Road between Moravia and West Pittsburg in Beaver County; it was moved and extended to a 2-county route in 1936, running from PA 51 in Moon Township/Allegheny County to PA 168 in Ohioville/Beaver County until its decommissioning in 1946. Thirty years later, the segment of PA 51 from Narrows Run Road (now University Boulevard) in Moon Township to its then-concurrency with PA 18 in Monaca was moved to its current alignment on former PA 930. The original route on Galilee Road is now an alignment of PA 168.
Pennsylvania Route 931 (Clinton Frankfort Road) ran from PA 18 in Frankfort Springs to U.S. 30 in the Clinton neighborhood of Findlay Township and was situated along the Beaver, Washington and Allegheny County lines.
Pennsylvania Route 932 ran from US 422 in Pulaski Township/Lawrence County to PA 318 near the PA/OH state line in Shenango Township/Mercer County. This is one of the very few defunct routes that lasted longer than most that were commissioned in 1928. It was downgraded in 1985 with two SR route numbers that changed at the county line: SR 4001 in Lawrence County and SR 3001 in Mercer County.
Pennsylvania Route 964 in Venango County first ran from the borough of Utica to U.S. 322 in Canal Township. In 1936, the route was extended and its southern terminus moved to a former alignment of PA 285 in Frenchcreek Township
Pennsylvania Route 966 in Clarion County first ran from U.S. 322/PA 66 in Clarion to an unnumbered road in Miola; this was extended in 1936 to PA 36 in Scotch Hill. PA 966 was decommissioned in 1969 and renumbered as a realignment of PA 68 which was truncated the following year to its current northern terminus at U.S. 322.
Pennsylvania Route 968 in Jefferson County first ran from U.S. 322 in Brookville to an unnumbered road in Warsaw Township. It was extended in 1936 with its new northern terminus at PA 949 in Polk Township. PA 968 is one of the longer lasting routes that were assigned in 1928; it was decommissioned in 1984 and reassigned as quadrant SR 4005.
One of the shortest state routes ever commissioned, Pennsylvania Route 990 in Allegheny County ran from then-PA 881 (East Pittsburgh-McKeesport Boulevard) to U.S. 30 in North Versailles. This road is now known as Navy-Marine Corps Way.
Pennsylvania Route 991 (Fifth Avenue) in Allegheny County ran from Westinghouse Avenue (at the junction of then-PA 881) in North Versailles to U.S. 30 in East McKeesport. After its decommissioning in 1946, PA 991 was reassigned as a realignment of current PA 148.
