Maryland Route 45 (MD 45) is a state highway in the U.S. state of Maryland. Known for most of its length as York Road, the state highway runs {{convert|30.06|mi|km}} from U.S. Route 1 (US 1) and US 40 Truck in Baltimore north to the Pennsylvania state line in Maryland Line, where the highway continues as State Route 3001 (SR 3001). MD 45 is the primary highway between Downtown Baltimore and Towson, the county seat of Baltimore County. North of Interstate 695, the state highway parallels I-83 and serves the suburban communities of Lutherville, Timonium, Cockeysville, and Hunt Valley. MD 45 also connects the northern Baltimore County communities of Hereford and Parkton. The state highway is maintained by the Maryland State Highway Administration in Baltimore County and by the Baltimore City Department of Transportation in the city, where the highway also follows Greenmount Avenue.

York Road, which follows the path of an 18th-century wagon road and 19th century turnpike, was one of the original state roads marked for improvement by the Maryland State Roads Commission in 1909. The state highway was constructed as an all-weather road in the mid-1910s from Baltimore to Hereford. The remainder of York Road to Maryland Line was built in the late 1910s and early 1920s. York Road was designated US 111 in 1927 and widened to handle the increasing traffic load in the late 1920s. York Road became a secondary route when a freeway was constructed from Baltimore to York and Harrisburg in the 1950s. US 111 was moved to this freeway as sections opened; the old road became MD 45. MD 45 fully replaced US 111 on York Road when the U.S. Highway was replaced by I-83 in the early 1960s.

Route description

MD 45 begins at an intersection with US 1 and US 40 Truck (North Avenue) at the northwest corner of Green Mount Cemetery in Baltimore. Greenmount Avenue continues south as a city street to Forrest Street and Monument Street east of Downtown Baltimore. MD 45 heads north as a four-lane undivided street between the Barclay and East Baltimore Midway neighborhoods and crosses over CSX's Baltimore Terminal Subdivision. The state highway continues north through Waverly, where the street passes St. John's Episcopal Church and intersects 33rd Street. MD 45 is paralleled to the east by Old York Road through Waverly and Pen Lucy. At 43rd Street, MD 45's name changes to York Road. The name change occurs where the highway exited the city limits of Baltimore between 1888 and 1917. MD 45 continues north as a five-lane road with center turn lane. Between Cold Spring Lane and Northern Parkway, the state highway passes through Mid-Govans, which is home to the Senator Theater.^[4]

MD 45 leaves the city limits and passes through the Baltimore County community of Rodgers Forge. The state highway passes along the eastern margin of Towson University before reaching the southern edge of downtown Towson, where MD 45 Bypass splits to the northwest along Burke Avenue. In the center of the county seat adjacent to the Towson Town Center shopping mall, MD 45 passes through the racetrack-shaped Towson Roundabout, where the state highway meets the southern end of MD 146 (Dulaney Valley Road) and east–west Joppa Road. On either side of the roundabout, the state highway narrows to two lanes for on-street parking. MD 45 heads northwest from the roundabout and meets the northern end of MD 45 Bypass (Bosley Avenue) before it passes east of the George Washington Carver Center for Arts and Technology and has a partial cloverleaf interchange with I-695 (Baltimore Beltway). The state highway continues north through the densely populated suburban area of Lutherville where the highway intersects Seminary Road, which heads west as MD 131. The west side of MD 45 is lined with commercial and industrial parks as it passes through Timonium. Between Timonium Road and Padonia Road, both of which head west to interchanges with I-83, the state highway passes along the eastern edge of the Timonium Fairgrounds, home of the Maryland State Fair and the Baltimore County 4-H Fair. The industrial parks continue past Warren Road in Cockeysville, where the highway crosses Beaver Dam Run. MD 45 meets the western end of MD 145 (Ashland Road) before arriving in Hunt Valley, where the highway intersects Shawan Road at Hunt Valley Town Center.^[2][4]

North of Shawan Road, MD 45 becomes a two-lane road that crosses Western Run and curves northeast before resuming its northward course through the community of Sparks, where the highway has an intersection with Belfast Road and passes several industrial parks. The state highway continues through the village of Hereford, which contains the western terminus of MD 138 (Monkton Road) and the eastern terminus of MD 137 (Mount Carmel Road) one block apart. North of Hereford, MD 45 passes west of Hereford High School and descends into the valley of Gunpowder Falls, where the highway closely parallels I-83. The two highways separate, with the state highway passing by the Half-Way House, a preserved toll house from the 19th century turnpike that is halfway between Baltimore and York. In Parkton, MD 45 intersects Middletown Road and passes over the Torrey C. Brown Rail Trail and Little Gunpowder Falls. North of the village, the state highway crosses to the west side of I-83 at a diamond interchange with the Interstate. The state highway intersects MD 439 (Old York Road) and Freeland Road in the community of Maryland Line before reaching its northern terminus at the Pennsylvania state line. The roadway continues north as SR 3001 (Susquehanna Trail) toward the borough of Shrewsbury.^[2][4]

MD 45 is a part of the National Highway System as a principal arterial from US 1 in Baltimore to Shawan Road in Hunt Valley except for the short stretch between MD 146 and the northern junction with MD 45 Bypass in Towson.^[2][10]

History

York Road was first constructed as a wagon road in the early 1740s to connect the new settlement of York with the port of Baltimore.^[11] In the 19th century, this road became part of the Baltimore and Yorktown Turnpike.^[11][13] When the Maryland State Roads Commission put together a state road system in 1909, York Road from North Avenue in Baltimore to Parkton was designated one of the original state roads to be improved.^[14] The first section of the old turnpike to be resurfaced with a {{convert|14|ft|m|adj=on}} wide macadam surface was from Washington Avenue just north of the center of Towson and the hamlet of Texas south of Cockeysville in 1913. The highway from the contemporary northern city limit of Baltimore near 42nd Street to Washington Avenue just north of the center of Towson was surfaced with bituminous concrete in 1914. York Road from Texas to Glencoe was resurfaced in 1914 and from there to the hamlet of Verona south of Hereford in 1915.^[15] The improved macadam road was extended to Parkton by 1919.^[16] York Road from Parkton to the Pennsylvania state line was paved in concrete in two sections completed in 1921 and 1923.^[17][18] Greenmount Avenue was reconstructed from 42nd Street to its southern end by 1924.^[18][20] In 1927, York Road and Greenmount Avenue north of North Avenue became part of US 111.^[21]

Early improvements to York Road included the construction of new bridges over Western Run and Gunpowder Falls in 1918 and 1924; these bridges remain in use.^[16][23][24] Other bridges included grade separations at the crossings of the Northern Central Railway at Cockeysville and Parkton built around 1930.^[25] US 111 was widened with concrete shoulders in much of Baltimore County in the mid- to late 1920s.^[20] York Road and Greenmount Avenue were widened and reconstructed in Baltimore in 1929 and 1930. By 1930, US 111 had a width of {{convert|40|ft|m}} from inside Baltimore to Towson, {{convert|20|ft|m}} from Towson to Parkton, and {{convert|18|ft|m}} from Parkton to the Pennsylvania state line.^[25] By 1934, the Maryland State Roads Commission recommended widening the U.S. Highway to {{convert|40|ft|m}} from Towson to Cockeysville and to {{convert|20|ft|m}} from Parkton to the Pennsylvania state line.^[28] The latter stretch was widened to {{convert|24|ft|m}} in 1946 and 1947.^[29]

Further widening of US 111 was not planned because York Road was to be bypassed by a freeway between Baltimore and Harrisburg. Construction on the Baltimore–Harrisburg Expressway got underway in 1948 between Timonium and Hunt Valley.^[30] The first portion of the freeway opened from Towson to Belfast Road north of Hunt Valley in December 1955, concurrent with the opening of the portion of the Baltimore Beltway between Falls Road and York Road.^[31] US 111 was moved to the freeway when the Baltimore–Harrisburg Expressway was completed to north of Hereford in 1957; MD 45 was assigned to York Road between the Beltway and the northern end of the freeway.^[31][33] A second, disjoint portion of MD 45 was assigned from north of Parkton to the Pennsylvania state line when the Baltimore–Harrisburg Expressway was completed between Parkton and the York area in 1959.^[31][35] When the final section of the US 111 freeway was completed between Hereford and Parkton in 1960, MD 45 was assigned to the stretch of York Road between those communities.^[31][37] US 111 and I-83 were co-signed on the freeway between Towson and Harrisburg until US 111 was decommissioned in 1963; the MD 45 designation was extended south into Baltimore to US 1 at that time.^[38]
