U.S. Route 1 in Maryland is an 81-mile segment of the U.S. highway that runs through central Maryland.

Route description

From Washington, D.C., U.S. Route 1 (a.k.a. Rhode Island Avenue) enters Maryland in the community of Mount Rainier. From there, it passes through Hyattsville (where it merges with Baltimore Avenue), College Park (including the University of Maryland campus), Beltsville, Muirkirk, Laurel, Savage, Jessup, Dorsey, and Elkridge, before entering Baltimore, where it follows Southwestern Boulevard, Wilkens Avenue, Monroe Street, Fulton Street, and North Avenue (the old northern boundary of Baltimore). It exits Baltimore to the northeast along Bel Air Road, through the towns of Overlea/Fullerton, Perry Hall, and Kingsville, until just north of Fallston, where Route 1 becomes the Bel Air Bypass. Finally, it becomes Conowingo Road after crossing MD Route 543. From that point north, the highway travels through rural areas to the Pennsylvania border, on a stretch which includes crossing the Susquehanna River atop the Conowingo Dam.

US 1 is paralleled by several major highways as it passes through Maryland, including Interstate 95, the Baltimore-Washington Parkway, U.S. Route 29 and U.S. Route 301. Thus, US 1 has lost its significance as a long distance route through the state. It is often congested, however, because it remains a major route in the individual towns it traverses.

Between Baltimore and Washington, D.C., Route 1 is also known as the Baltimore-Washington Boulevard and (closer to D.C.) Baltimore Avenue and Rhode Island Avenue.

History

The Washington and Baltimore Turnpike was chartered by the state on December 17, 1812, and ran from the intersection of Pratt and Eutaw Streets, then on the Baltimore city line, to the D.C. border.

North of Baltimore City, the Baltimore and Jerusalem Turnpike Company was incorporated by the Maryland General Assembly in 1867. It ran from the eastern city line at the modern-day town of Overlea/Fullerton, through Perry Hall, (running immediately adjacent to the original Perry Hall Mansion) near where most settlement existed at the time, through rural Kingsville, and ended at the Harford County line. In 1909, the State Roads Commission opted to use the right-of-way of this turnpike for the construction of U.S. 1 northeast of the city.

The original Baltimore-Washington Blvd. was first paved by the state of Maryland in 1914, and became part of US 1 when the U.S. highway system was formed in 1926.

The earliest reference to a numbered route along this corridor was the unmarked State Road No. 1 in 1908 between Baltimore and Washington.[1][2] The route was routed along the general path of present-day US 1 between Baltimore and Washington.

Route 1 in downtown College Park has been closed because of post-game revelry (dubbed 'riots' by locals) by students at the University of Maryland, College Park; most notably following the 2002 NCAA Final Four when the Maryland Terrapins captured the NCAA National Championship.

Miscellanea

US 1's alignment between the Baltimore city line and the southern terminus of US 1 Business south of Bel Air, 13.5 miles in length, is one of the few arterial highways in Maryland that has not been bypassed in any way. It has remained in this form due to the presence of I-95 and US 40.
