The following is a list of state highways in Maryland shorter than one mile (1.6 km) in length with route numbers between 2 and 699. Most of these highways act as service roads, old alignments of more prominent highways, or connectors between one or more highways. Many of these highways are unsigned and have multiple segments with the same number. Several of these highways have their own articles; those highways are summarized here and a link is provided to the main article. This list does not include highways where at least one highway of that number is at least one mile in length. All highways at least one mile in length have their own article. The highways shorter than one mile with the same number are covered in the main article for the highway.
Maryland Route 169 is the designation for Maple Road, a 0.97-mile (1.56 km) state highway in Linthicum in northwestern Anne Arundel County. The highway begins at Hammonds Ferry Road and heads east as a two-lane road through a residential area. MD 169 has a grade crossing of the Baltimore Light Rail just prior to its intersection with MD 170 (Camp Meade Road). The highway reaches its eastern terminus at MD 648 (Baltimore–Annapolis Boulevard).
Maryland Route 219 is the unsigned designation for Ninth Street, which runs 0.22 miles (0.35 km) from the intersection of US 219 and MD 135 north to High Street within Oakland. MD 219 is state-maintained from US 219 to Green Street and maintained by the town of Oakland from there to High Street. The state highway follows the southernmost part of the alignment of the future Oakland Bypass.
Maryland Route 221A is the unsigned designation for a 0.58 mi (0.93 km) section of Ritchie–Marlboro Road around that highway's dumbbell interchange with I-95/I-495 (Capital Beltway) (Exit 13) in Largo.
Maryland Route 250A is the unsigned designation for Old Virginia Road, which runs 0.19 mi (0.31 km) from US 13 Business east to the intersection of US 13 and US 113 within Pocomoke City. The state highway is the southernmost part of the second alignment of US 113 in Pocomoke City. MD 250A was assigned shortly after US 113 was rolled back to terminate at the Pocomoke City Bypass, US 13, in the 1960s.
Maryland Route 268, which is known as North Street, runs 0.95 miles (1.53 km) from Main Street north to MD 279 within Elkton. The state highway begins at Main Street in downtown Elkton. Main Street is one-way eastbound; the parallel street that allows westbound traffic and provides access to MD 213 (Bridge Street) is High Street one block to the north. MD 268 heads north through a commercial area that transitions to a residential area at Railroad Avenue, where the highway veers slightly to the west to cross over the Amtrak Northeast Corridor. The old alignment, Old North Road, consists of pair of stubs on the south and north sides of the tracks with unsigned designations MD 727 and MD 727A, respectively. MD 268 continues north through a residential area, passing between Big Elk Creek and Elkton Middle School before reaching its northern terminus at MD 279 (Elkton Road/Newark Avenue). MD 268 is the old alignment of MD 279 within Elkton. North Street was paved by 1921. MD 279's overpass of the Pennsylvania Railroad (now Amtrak) was constructed around 1930. MD 268 was assigned to North Avenue when MD 279 was extended west to US 40 to bypass the center of Elkton in 1967.
Maryland Route 284, which is known as Hemphill Street, runs 0.25 miles (0.40 km) between two intersections with MD 285 in Chesapeake City in southern Cecil County. MD 284 begins at MD 285 (Biddle Street) in the town of Chesapeake City one block north of the Chesapeake and Delaware Canal. The state highway heads north as a two-lane road through a residential area. Just after leaving the town limits of Chesapeake City, MD 284 curves to the west and reaches its northern terminus at MD 285 (Lock Street). MD 285 heads north to a junction with MD 213 (Augustine Herman Highway). Hemphill Street was part of the original Cecilton–Elkton highway passing through Chesapeake City that was designated for improvement by the Maryland State Roads Commission in 1909. This highway, which was paved through Chesapeake City in 1915, followed Hemphill Street south to the canal, where it turned west and crossed a wooden, one-lane bridge to the south side of the town. The wooden bridge across the canal was dismantled ahead of the expansion and straightening of the Chesapeake and Delaware Canal in the 1920s. A vertical lift bridge was constructed by the U.S. Army Corps of Engineers connecting Lock Street on the north side with George Street on the south side of the town in 1926, bypassing Hemphill Street, which was later designated MD 284.
Maryland Route 308 is the designation for a portion of South Main Street in Federalsburg, Caroline County running from Maryland Route 313 north to the end of state maintenance. It is among the shortest of all state highways at 0.12 miles (0.19 km). Although not signposted, it does appear in official documents and some commercial maps.
Maryland Route 324 is the unsigned designation for Maple Avenue, which runs for 0.40 mi (0.64 km) between MD 16/MD 331 and the southern town limit of Preston, where the highway continues as county-maintained Choptank Road.
Maryland Route 327, which is known as Ikea Way, runs 0.36 miles (0.58 km) from MD 7 east to Marion Tapp Parkway and Firestone Road within Perryville. MD 327 begins at an intersection with MD 7 (Broad Street) on the eastern edge of the town of Perryville. The state highway heads southeast as a two-lane road, crossing over the Amtrak Northeast Corridor. MD 327 reaches its eastern terminus at an intersection with Marion Tapp Parkway and Firestone Road. Firestone Road leads to the entrance of an IKEAdistribution center. Marion Tapp Parkway leads to the entrance of the adjacent Perryville Wastewater Treatment Plant and to Perryville Community Park located at the Perry Point promontory east of the Perry Point VA Medical Center property. A grade-separated crossing of the Pennsylvania Railroad at the site of MD 327 was constructed in 1942 and reconstructed in 1968 around the same time Firestone Plastics opened a chemical plant on the present site of the IKEA distribution center. MD 327 was designated in 1968 when the railroad crossing was reconstructed. The state highway had no name as of 1999; it was designated Firestone Road in 2001 and Ikea Way in 2004 shortly after the opening of the IKEA distribution center.
Maryland Route 334 is a state highway in Talbot County, Maryland. It runs along Port Street from Maryland Route 322 on the western edge of Easton, eastward to Washington Street. Maryland Route 334 follows Port Street in Easton, starting in the west at the intersection with MD 322 (Easton Parkway).

Maryland Route 432 is the unsigned designation for Glen Oak Lane, which runs 0.25 mi (0.40 km) from the intersection of Guilford Road and Oakland Mills Road east to a cul-de-sac adjacent to I-95's interchange with MD 32 (Exit 38) in Columbia.
Maryland Route 460, which is known as Hall Highway, runs 0.78 miles (1.26 km) from McCready Memorial Hospital east to MD 413 within Crisfield in southwestern Somerset County. The highway begins just north of the McCready Memorial Hospital property on a peninsula between Daugherty Creek and the Little Annemessex River. The roadway continues north as county-maintained Byrd Road. MD 460 heads south, entering the city limits of Crisfield and passing through the hospital grounds, where the highway is flanked by perpendicular parking spaces. The state highway turns east and crosses the Little Annemessex River, then passes through a residential neighborhood where the highway intersects Wynfall Avenue, which provides full access to MD 413. MD 460 reaches its eastern terminus at southbound MD 413 (Maryland Avenue). There is no direct access to northbound MD 413 (Richardson Avenue). McCready Memorial Hospital was founded in 1923 as a memorial to Edward W. McCready, a cork industry scion and Crisfield native who was killed in a train–automobile collision on the Crisfield–Westover road in 1919. MD 460 was constructed around 1933 to provide a more direct connection between the hospital and the populated areas of Crisfield.

Maryland Route 537 is an unsigned state highway in Cecil County, Maryland running through Chesapeake City. The highway is divided into three segments, all of which are designated with a lettered suffix. A piece of Maryland 537 begins as a branch from Maryland 284 in Chesapeake City, continuing as Lock Street southward through the city past Maryland 285, and stopping at Bank Street and the Chesapeake and Delaware Canal. Across the canal, the route picks up again in the same direction as George Street, crossing Maryland 286, and then ending at the Augustine Herman Highway (Maryland 213). Maryland Route 537 used to cross MD 213 and parallel it along Basil Road before rejoining it, however this section has been removed from the state highway system.
Maryland 537 is the original route of Maryland 213 through Chesapeake City, which was diverted when a different site was found for a high bridge across the canal. The current bridge on Maryland 213 was opened in 1949 after the earlier vertical lift bridge connecting George Street with Lock Street was destroyed in an accident with the tanker Franz Klasen in 1942.
Maryland Route 568 is the designation for Hatchery Road, a 0.41 mi (0.66 km) spur that runs from MD 367 in Bishopville north to the Delaware state line, where the highway continues as Bishopville Road toward Selbyville. MD 568 was originally a segment of MD 368; the roads received their present designations in 1950.
Maryland Route 591 is a pair of state highways that form the old alignment of U.S. Route 1 (US 1) near Conowingo in northwestern Cecil County. MD 591A and MD 591B run on the northwest and southeast sides, respectively, of a now-removed 1885 bridge over Octoraro Creek.
MD 591A is designated Colora Road and has a length of 0.28 miles (0.45 km). The state highway begins at an oblique intersection with US 1 (Conowingo Road) on the northwest side of Octoraro Creek. Opposite Colora Road is Connelly Road, the original alignment of US 1 prior to 1928. MD 591A passes a few homes and parallels the right bank of Octoraro Creek before reaching its eastern terminus at a dead end adjacent to the site of the former bridge.
MD 591B is designated Porters Bridge Road and has a length of 0.80 miles (1.29 km). The state highway begins at a dead end adjacent to the site of the former bridge on the left bank of Octoraro Creek. MD 591B heads east, crossing Love Run and intersecting Colora Road. The state highway turns northeast, paralleling the creek to the site of the present US 1 bridge, then turns east past several homes to an oblique intersection with US 1.
A bridge has existed at this site on Octoraro Creek since a bridge was constructed to serve Richard Porter's mill on the northwest side of Octoraro Creek in the late 18th century. A wooden covered bridge was constructed at the site around 1858 and washed away in a flood in 1884. A metal Pratt through truss bridge was constructed to replace Porter's Bridge in 1885. This truss bridge served the original state road, later designated US 1 in 1927. The state road west toward Conowingo was paved in 1911, while the state road east toward Rising Sun was completed by 1919. Porter's Bridge was bypassed when a relocation of US 1, including a new bridge over Octoraro Creek upstream, was completed in 1934. The old alignment was designated MD 591. Porters Bridge was closed in January 1978 after a storm caused irreparable damage to the eastern approach to the bridge. The bridge was dismantled around 2002.
Maryland Route 617 is the unsigned designation for an unnamed road connecting Maryland Route 16A (Beauchamp Branch Road) north to Maryland Route 16 (Harmony Road) in Caroline County. The route is 0.35 miles (0.56 km) long.

Maryland Route 658 is an unsigned state highway that runs 0.84 miles (1.35 km) from MD 53 north to US 40 Alternate within La Vale. The highway west of I-68 is part of US 220 Truck, which provides access from eastbound I-68 to southbound US 220 in Cresaptown for trucks due to a truck prohibition on the eastbound exit ramp for I-68's interchange with US 220. MD 658 begins at an intersection with MD 53 (Winchester Road) and heads northeast as Vocke Road, a four-lane divided highway. The state highway passes the Country Club Mall and the District 6 offices of the Maryland State Highway Administration before intersecting a segment of Braddock Road, which is unsigned MD 949. MD 658 intersects entrance and exit ramps from Exit 40 of eastbound I-68 and US 40 (National Freeway). The highway passes under the freeway and meets an exit ramp from westbound I-68 and the western terminus of MD 49 (Braddock Road) at the next intersection, where the highway's name changes to Campground Road. MD 658 turns north, crossing Braddock Run, and reduces to a four-lane undivided highway before reaching its northern terminus at US 40 Alternate (National Pike). MD 658 was assigned to Campground Road as a connector between US 40 and MD 49 in 1939. The state highway was extended south along Vocke Road to MD 53 around 1948.
