Pennsylvania Route 45 (PA 45) is an 86-mile-long (138 km) state highway located in central Pennsylvania. PA 45 is called the Purple Heart Highway. The western terminus of the route is at Pennsylvania Route 453 in the Morris Township near the community of Water Street. The eastern terminus is at Pennsylvania Route 642 west of the small town of Mooresburg.


From approximately 1830 to 1903, the section between Lewisburg and Mifflinburg was owned and operated by the Lewisburg and Mifflinburg Turnpike Company.[2] The section west of Mifflinburg (formerly Youngmanstown) was built by the Bellefonte, Aaronsburg and Youngmanstown Turnpike Company, chartered in 1825.[3]

When Pennsylvania's "traffic routes" were established in 1925, PA 45 was originally signed from Herndon to Easton.[4] The 1928 revision expanded this route westward; PA 45 was signed on two different sections, the connection between them being signed as part of US 120 (later US 122, now PA 405, PA 147, and PA 61). The "middle" section was signed from Water Street to Montandon, between Milton and Northumberland,[5] and the east section from Ashland to Easton.[6]

In 1928, the route was under construction from Indianland to Beersville and completed the following year on the Ashland to Easton section. In 1930, the route was paved from Lehigh Gap to Indianland on the eastern section. In 1934, the eastern terminus was moved from Walnut Street to 13th Street in Easton.

In 1932, a western section of PA 45 was opened from Belsano to US 22 near Sankertown and Cresson. The route replaced US 422 from Belsano to Ebensburg and US 22 from Ebensburg to Cresson when those designations were placed on a straighter route.[7] In 1936, the eastern terminus of the middle section was moved from Montandon to Mausdale. In 1946, the eastern terminus of the western section was truncated from Cresson to Ebensburg. Until 1952, the middle section entered Mooresburg on a different route. In 1951, construction began on a bypass which opened in 1952. In 1955, the eastern terminus in the eastern section was moved from 13th Street to Third Street in Easton.[8]

Until 1961, there was a break between Mausdale and Ashland, that was connected when PA 54 was truncated to Mausdale.[8] Also in 1961, the western section of PA 45 was decommissioned; the piece of PA 45 between Belsano and Nanty Glo became part of an extension of PA 933[9][10] and is currently part of PA 271.

In 1962, the route was changed from going into State College via US 322 and then PA 26, to go straight from PA 26 to Boalsburg. In 1966 the eastern section was renumbered as PA 248, leaving the current alignment the only one to hold the designation.[8] The eastern terminus was fixed at its current location, with the road reverting to PA 642 from Mooresburg to Mausdale and to PA 54 south/east of Mausdale.[11]

Bannered routes[edit]

PA 45 Truck (Mifflinburg)[edit]

PA Route 45 Truck
Location: Mifflinburg, Pennsylvania
Existed: 1969–present

Pennsylvania Route 45 Truck is a 2-mile-long (3.2 km) truck route in Mifflinburg, Union County, Pennsylvania. Narrow streets within the borough are avoided by this designation, and a complicated intersection with Pennsylvania Route 304, which does not contain turning lanes, is bypassed. The route is concurrent with other highways for its entire length: it begins as a portion of Pennsylvania Route 104 southbound, then it is cosigned with Truck 304, before traveling back northbound along Route 304.

PA 45 Truck (Huntingdon County)[edit]

PA Route 45 Truck
Location: Huntingdon County, Pennsylvania
Existed: 1969–present

At mile 2.4, a very old overpass, constructed from blocks of stone, carries the Pittsburgh Line over PA 45. Passage of large trucks is impossible as it allows only 8'2" of clearance, and the speed limit on the associated hairpin turn is 10 mph. Pennsylvania Route 45 Truck is a 17-mile-long (27 km) truck route designed to avoid this bottleneck, other sharp turns, and steep grades along mainline PA 45 in western Huntingdon County, Pennsylvania. The route is somewhat antiquated, concurrent entirely with other routes, and significantly longer than the twisty mainline. Traveling mostly in Franklin Township and Warriors Mark Township, the route begins in the west by branching northbound along Pennsylvania Route 453, before continuing west along Pennsylvania Route 550, and traveling south along Pennsylvania Route 350 to meet up with its parent.
