Maryland Route 450
Maryland Route 450 is a state highway in the U.S. state of Maryland. The state highway runs from U.S. Route 1 Alternate in Bladensburg east to US 50/US 301 and MD 2 near Arnold. MD 450 forms a local complement to US 50 from near Washington, D.C. through Annapolis. In Prince George's County, the highway is a four- to six-lane divided highway that serves Bladensburg, Landover Hills, New Carrollton, Lanham, and Bowie. In Anne Arundel County, MD 450 connects Crofton with Parole and Annapolis with the portion of the county east of the Severn River. The highway serves as one of the main streets of Annapolis, including the state capital's historic core, and is the primary vehicular access to the U.S. Naval Academy.
MD 450 is the old alignment of US 50 from Bladensburg to Parole and of MD 2 from Parole to the Severn River. The MD 2 portion of the highway was constructed in the early to mid-1910s except for the first modern bridge across the Severn River, which was completed in the mid-1920s. The US 50 section of the highway was started from either end in the late 1910s and completed in the mid-1920s, shortly before the US 50 and MD 2 designations were assigned to the respective highways. As they were part of the main highways between Washington and Annapolis and from Annapolis to Baltimore, all segments of what is now MD 450 were improved in the 1920s and 1930s. The highway from the Severn River to Arnold was constructed as a relocated MD 2 in the late 1930s. MD 450 was first assigned from Crofton to Arnold in 1954 after US 50 was moved to its present freeway from Bowie to Arnold. The state highway was extended west to Bladensburg in 1962 when the US 50 freeway was completed from Bowie to Washington. MD 450 was expanded to a divided highway from Bladensburg to Lanham in the mid-1960s and from Lanham to Bowie in the early to mid-2000s.
Route description
MD 450 is a part of the National Highway System as a principal arterial from MD 201 to MD 202 in Bladensburg, from MD 704 in Lanham to MD 3 in Bowie, and from US 50/US 301 in Parole to those same highways and MD 2 at the route's eastern terminus in Arnold.Bladensburg to Bowie
MD 450 begins at a directional intersection with US 1 Alternate in the town of Bladensburg just southeast of the confluence of the Northwest and Northeast Branches of the Anacostia River to form the river proper. US 1 Alternate heads southwest as Bladensburg Road into Colmar Manor and north as Baltimore Avenue toward Hyattsville. Adjacent to the center intersection of the junction is the Peace Cross, a memorial to World War I soldiers. MD 450 heads east as Annapolis Road, a four-lane road with a center left-turn lane that passes under the Alexandria Extension of CSX's Capital Subdivision railroad line. East of the railroad underpass, the highway has a partial cloverleaf interchange with MD 201. 48th Street, which connects MD 450 with northbound MD 201 in both directions, is unsigned MD 769C. Within and surrounding the interchange are the historic William Hilleary House, Market Master's House, and the estate Bostwick.East of 48th Street, MD 450 intersects the southern end of Edmonston Road, which is unsigned MD 769B. The highway meets the northern end of MD 202 at an acute intersection; there is no direct access from westbound MD 450 to southbound MD 202. MD 450 continues as a six-lane divided highway and leaves the town of Bladensburg at its partial cloverleaf interchange with the Baltimore-Washington Parkway. The highway passes between the town of Landover Hills and the unincorporated area of Woodlawn and intersects MD 410. MD 450 briefly passes through the city of New Carrollton, intersecting 85th Avenue, before its partial cloverleaf interchange with Interstate 95 /I-495. East of the Beltway in the center of Lanham, westbound MD 450 has a signalized right-in/right-out intersection with Princess Garden Parkway and the route has a partial interchange with the west end of MD 564. Eastbound MD 450 has access to Princess Garden Parkway by turning around at MD 564's intersection with Cipriano Road, but there is no direct access from MD 564 to eastbound MD 450, from westbound MD 450 to MD 564, or from Princess Garden Parkway to either eastbound MD 450 or MD 564. MD 450 reduces to four lanes on its bridge across the ramp from eastbound MD 450 to MD 564 and Amtrak's Northeast Corridor railroad line.
MD 450 meets the northern end of Whitfield Chapel Road just east of the railroad bridge. The highway passes along the southern edge of the unincorporated area of Seabrook, then meets the eastern end of MD 704. MD 450 continues as a six-lane divided highway and intersects MD 953. East of MD 193, which heads north as Glenn Dale Boulevard and south as Enterprise Road, MD 450 reduces to four lanes. Just after the route enters the city of Bowie, Old Annapolis Road splits to the east as MD 450 veers northeast to cross over CSX's Popes Creek Subdivision railroad line and intersect MD 197. The highway passes south of Bowie High School and becomes a four-lane undivided highway at Stonybrook Drive. It drops to two lanes as it leaves the city of Bowie east of Race Track Road and west of historic Sacred Heart Church. MD 450 then expands to a four-lane divided highway just west of its intersection with MD 3. MD 450 turns to run concurrently with MD 3. The two state highways follow a six-lane divided highway over the Patuxent River at Priest Bridge, thereby crossing the Prince George's-Anne Arundel county line.
Crofton to Arnold
MD 450 splits from MD 3 onto Defense Highway, which starts as a four-lane divided highway but gradually reduces to two lanes as the route passes along the southern edge of Crofton. At the southeast end of the unincorporated community, the highway intersects MD 424. MD 450 continues along a curvy path through a forested area in which it crosses the North River and the South River and intersects Crownsville Road, which leads north to the Maryland Renaissance Festival. MD 450 passes under I-97 with no access and enters Parole, where the highway expands to four lanes with a center turn lane. The highway turns southeast onto West Street at its intersection with MD 178 ; the east leg of the intersection is an entrance to the Westfield Annapolis shopping mall. MD 450 has an oblique four-ramp partial cloverleaf with US 50/US 301, which run concurrently with unsigned I-595. The streets that form the fourth legs of the intersections with the westbound and eastbound ramps with the freeway are Jennifer Road and Riva Road, respectively.MD 450 temporarily expands to a divided highway from west of MD 2 to east of MD 393 ; between those two highways, MD 450 enters the city of Annapolis. The highway reduces to two lanes east of Chinquapin Round Road and meets the southern end of MD 435 and the northern end of MD 387 at the Westgate Circle roundabout next to Annapolis National Cemetery. MD 450 continues into the Colonial Annapolis Historic District as a municipally maintained street. The road surface changes to brick for the one block before the highway enters Church Circle, a traffic circle that circumscribes St. Anne's Church. The streets that emanate from the circle include Franklin Street, which leads to the Banneker-Douglass Museum; South Street, which passes the Old City Hall and Engine House; Duke of Gloucester Street and Main Street, a non-parallel pair of one-way streets that head toward and from the city's docks; School Street, which leads to State Circle, which is unsigned MD 797 and circumscribes the Maryland State House; Northwest Street, which enters the circle from the namesake direction; and College Avenue, onto which MD 450 continues.
MD 450 passes Government House, the residence of the Governor of Maryland, and meets the southern end of MD 70 directly northwest of the State House. The highway passes along the edge of St. John's College to King George Street, onto which the route turns northwest. MD 450 follows King George Street along the edge of the U.S. Naval Academy reservation to College Creek, where the highway becomes state maintained again and leaves the city of Annapolis. The highway continues through the census-designated place of Naval Academy, which includes the grounds of the military academy, to the northern end of MD 435, where MD 450 turns northeast onto Baltimore–Annapolis Boulevard and, after a few more blocks through the reservation, the highway crosses the Severn River on the high-level Naval Academy Bridge. At the north end of the bridge, the highway meets the southern end of MD 648, which leads to an access road to Jonas Green Park on the north side of the bridge. MD 450 continues along Governor Ritchie Highway, a four-lane divided highway that contains the Maryland World War II Memorial in the median just north of MD 648. The highway curves to the northwest and MD 450 reaches its eastern terminus at a three-level interchange with US 50/US 301/MD 2 just east of the Severn River Bridge in Arnold. After a diversion through the interchange, Governor Ritchie Highway continues north toward Baltimore carrying MD 2.
History
Original construction
MD 450 from Bladensburg to the Severn River was proposed as one of the original state roads laid out by the Maryland State Roads Commission in 1909. The first portion of the highway was built as a concrete road from Solomons Island Road east to the city limits of Annapolis at Spa Road in 1914. The portion of the highway from Wagner Street at the city limits of Annapolis to the Severn River was proposed as the southernmost section of the Baltimore-Annapolis Boulevard, which was completed from the north side of the Severn River to Glen Burnie between 1910 and 1912. After litigation between the roads commission and Anne Arundel County, the result of which required the state to replace the bridge across College Creek, MDSRC constructed a new bridge across the creek in 1914 and 1915. The highway through the Naval Academy reservation from College Creek to the south side of the Severn River was built as a macadam road in 1916. The final gap in the Baltimore-Annapolis Boulevard was filled when the first modern Severn River Bridge was completed in 1924. This concrete bridge, which had a roadway width of and a steel bascule draw with a horizontal clearance of, replaced a narrow one-lane bridge.None of the highway from Bladensburg to Parole was completed by 1915. Construction of this highway started after a 1918 appropriation from the Maryland General Assembly specifically to construct the National Defense Highway, so named because it would connect the national capital with the Naval Academy. The first section built was from the Baltimore-Washington Boulevard east to approximately the location of the Baltimore-Washington Parkway in 1919. The second section of the Defense Highway, from there to near what is now MD 410 in Landover Hills, was started that same year and completed by 1921. Near Annapolis, another portion of the highway was built near the Annapolis Waterworks in 1920 and 1921. The western portion was extended east through Lanham to the Washington, Baltimore and Annapolis Electric Railway at Buena Vista near what is now MD 704 by 1923. The portion of Robert Crain Highway with which the Defense Highway crosses the Patuxent River was paved by 1923; a new reinforced concrete girder bridge was completed at the site in 1925. Other major structures along the route included a steel and concrete girder bridge across the Popes Creek Subdivision near Bowie in 1926 and reinforced concrete girder bridges across the North River and the South River completed in 1925. The fully concrete Defense Highway was finished in December 1926.
