Washington, D.C. alternate route

U.S. Route 1 Alternate is an alternate route forming a loop off U.S. Route 1 between Washington, D.C., and Hyattsville, Maryland.

;Route description
In the District of Columbia, U.S. 1 Alternate splits from U.S. 1 at the intersection of Constitution Avenue NW and 6th St. NW. U.S. 1 goes up 6th St. NW on its way to the intersection of Rhode Island Ave. NW. U.S. 1 Alternate stays on Constitution Avenue NW/NE as it traverses Capitol Hill, then follows Maryland Avenue NE, going around Stanton Park, to the Starburst Intersection comprising Maryland Avenue, Florida Avenue, H Street, Bladensburg Road, 15th Street NE, and the DC Streetcar Line. U.S. 1 Alternate then follows Bladensburg Road NE, which takes it into Prince George's County, Maryland after an at-grade intersection with New York Avenue NE ( U.S. 50) and after passing under Amtrak's Northeast Corridor. After passing through Colmar Manor and Cottage City, the road enters Bladensburg and turns onto Baltimore Avenue toward Hyattsville, where it rejoins U.S. 1 at Rhode Island Avenue.

US 1 Alternate crosses Eastern Avenue NE and enters the state of Maryland from the District of Columbia in Prince George's County. The route heads northeast along the partially four-lane divided Bladensburg Road passing industrial areas and warehouses on the northwest and the Fort Lincoln Funeral Home and Cemetery on the southeast straddling the southeastern boundary of the town of Cottage City. US 1 Alternate crosses over Dueling Creek adjacent to the Bladensburg Dueling Grounds on the southeast before heading into a commercial area where the route begins to follow the northwestern boundary of the town of Colmar Manor. In this area, the route insects the southern terminus of Maryland Route 208 (38th Street), before continuing along the town line and passing through a mix of residential and commercial areas. US 1 Alternate leaves the boundary between Colmar Manor and Cottage City as it crosses over the Anacostia River just to the southeast of the confluence between its Northeast and Northwest Branches and enters the town of Bladensburg. Immediately after crossing the river, the route's median for its directional Y intersection with the eastern terminus of MD 450 (Annapolis Road), which is the old alignment of US 50 in the capital region of Maryland which heads east into downtown Bladensburg. In the middle of the insection is a Maryland memorial for World War I soldiers known as the Peace Cross.

Past MD 450, US 1 Alternate curves north and its name changes to Baltimore Avenue passing industrial areas on the east and the Old Port of Bladensburg Community Park on the west. The route leaves Bladensburg at its crossing over the Northeast Branch and enters the city of Hyattsville. The route narrows to a two-lane undivided road and continues through a mix of residential, commercial, and industrial areas. US 1 Alternate reaches an at-grade railroad crossing with a component of the wye junction between CSX's Capital Subdivision line and its Alexandria Extension. A short distance past the crossing, the route enters a long bridge with a sweeping curve that crosses over the Capital Subdivision before the route reaches its northern terminus at US 1 (Baltimore Avenue) in downtown Hyattsville. Baltimore Avenue turns northward on US 1, taking over that route name from US 1 Alternate through the northern suburbs of Prince George's County including Riverdale Park, University Park, College Park, Beltsville, and Laurel.

;History
In the 1940s, this route was known as Bypass US 1, and was cosigned with U.S. Route 50 Alternate and Maryland Route 411.
