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.

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.

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 The Maryland State Highway Administration (abbreviated MDOT SHA or simply SHA) is the state transportation business unit responsible for maintaining Maryland's numbered highways outside Baltimore City. Formed originally under authority of the G ...
(MDSRC) in 1909. The first portion of the highway was built as a concrete road from Solomons Island Road (now MD 393) 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 (now MD 648), 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

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

(WB&A) 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.

When MDSRC first assigned state route numbers in 1927, MD 2 followed the present course of MD 450 from Solomons Island Road (now MD 393) to the north end of the Severn River Bridge, where the state highway continued along the Baltimore–Annapolis Boulevard. Improvements to the highways began immediately after they were numbered. The portion of MD 2 through the Naval Academy reservation was widened to with a pair of concrete shoulders in 1927.

(now US 1 Alternate) at the Peace Cross in Bladensburg east to MD 564 in Lanham and from MD 387 in Annapolis west to MD 178 in Parole, and to from Lanham to Parole. The first efforts for the mass widening of these highways came in 1938. That year, US 50 was widened to immediately to the east of the Peace Cross intersection in Bladensburg. In addition, the present alignment of MD 450 from the Severn River north to Arnold was completed as the southernmost portion of Governor Ritchie Highway. This segment of the new highway was initially completed as a two-lane highway, the present southbound lanes. The northbound lanes of the new MD 2 were completed from Annapolis to Arnold in 1940. The Peace Cross intersection was channelized and US 50 was expanded to a width of from Bladensburg to Lanham between 1940 and 1942. By 1940, MDSRC recommended the Defense Highway be completed rebuilt, preferably on a new location. The roads commission suggested widening of the Severn River Bridge by 1942. However, by 1944, a new bridge was proposed upstream of the existing bridge because the U.S. Navy desired a relocation. US 50 was extended east along modern MD 450 through Annapolis and across the Severn River to what had been MD 404 as part of its extension to Ocean City in 1949.


Replacement and recent improvements

Construction on the Annapolis–Washington Expressway (now John Hanson Highway) began in 1949 between US 301 in Bowie and what is now MD 450 in Parole. The new freeway opened to traffic in 1952. Construction on the new bridge over the Severn River began in 1950 and was completed in 1952, the same year work began on the Annapolis Bypass between Parole and Arnold. The Annapolis Bypass opened from MD 450 in Parole to the three-level Ritchie–Revell interchange between US 50, MD 2, and MD 450 in June 1954. That same year, US 50 was moved to the new freeway from Bowie to Arnold and MD 450 was assigned to the old highway from US 301 (now MD 3) in Crofton to its present eastern terminus in Arnold. MD 450 was expanded to a divided highway from west of MD 2 to east of MD 393 in 1956. In addition, the portion of MD 450 that is concurrent with MD 3 was expanded to a divided highway, including a new bridge across the Patuxent River, between 1956 and 1958. The only major changes to MD 450 in Anne Arundel County since the 1950s have been bridge replacements. The highway's bridge across College Creek was replaced in 1987. The Severn River Bridge was replaced with the Naval Academy Bridge in 1995. In Prince George's County, the extension of John Hanson Highway west toward Washington began in 1953. The freeway was completed west to MD 704 in 1957. US 50 remained signed along Defense Highway in Prince George's County; instead, the new freeway and MD 704 southwest into Washington were designated Temporary US 50 by 1958. US 50 was assigned to John Hanson Highway west of US 301 when the freeway was completed into Washington in 1962. That same year, MD 450 was extended west along US 50's old route to its present western terminus at US 1 Alternate in Bladensburg. MD 450's interchange with MD 201 was constructed in 1954 and 1955. Starting in 1956, the Peace Cross intersection was raised to a higher elevation above the Anacostia River and reconstructed to reduce the risk of flooding. The first divided highway segments in the county were immediately to the east of the MD 202 split and from the Baltimore–Washington Parkway east to Landover Hills, which were expanded in 1963. The gap between the divided highway sections was filled in 1965. MD 450 was expanded to a divided highway from just west of the Capital Beltway to MD 564 in Lanham in 1966 and between Landover Hills and the Beltway in 1967. MD 450 was renamed Annapolis Road in Prince George's County in 1970. In 1985, the road was expanded to a divided highway on either side of its modern intersection with MD 193, which had been relocated onto Glenn Dale Boulevard that year. MD 450 was expanded to a divided highway from MD 564 to Whitfield Chapel Road east of the Amtrak Northeast Corridor in 1993; its interchange with MD 564 was built the same year. The first step in expanding the highway from Lanham to Bowie occurred in 2000 when the MD 704 intersection was relocated and the highway was widened from Forbes Boulevard to just east of the new MD 704 intersection. The following year, the divided highway was extended east from MD 704 to the existing divided highway at the MD 193 intersection. In 2005, the expansion of MD 450 from Lanham to Bowie was completed when the segments from Whitfield Chapel Road to Forbes Boulevard and from MD 193 to east of Stonybrook Drive in Bowie was completed. The only major relocation in the highway was from west of the Popes Creek Subdivision to east of MD 197. The old road from the western split to MD 197 was redesignated MD 450B.

MD 450 is signed east–west from US 1 Alt in Bladensburg to MD 435 in Naval Academy and north–south from MD 435 to US 50/US 301/MD 2 in Arnold.


Auxiliary routes

MD 450 has six auxiliary routes. MD 450A is in Lanham; the remainder are in Bowie. *MD 450A is the designation for an unnamed segment of the old alignment of MD 450 that parallels the westbound direction of the highway at its intersection with MD 704 in Lanham. MD 450A was assigned in 2000 when MD 450 was relocated at the MD 704 junction in Lanham. *MD 450B, signed as MD 450 Old, is the designation for Old Annapolis Road, which runs from MD 450 east to MD 197. The highway starts at a right-in/right-out intersection with eastbound MD 450. MD 450B starts heading south, then turns east at its intersection with MD 450C. The highway meets the southern end of MD 450E, which provides full access to MD 450, then veers away from MD 450.
