Maryland Route 214 (MD 214) is a state highway in the U.S. state of Maryland. Known for most of its length as Central Avenue, the highway runs from Southern Avenue and East Capitol Street at the District of Columbia boundary in Capitol Heights east to Beverly Beach. MD 214 connects the central Prince George's County suburbs of Capitol Heights, Seat Pleasant, Largo, and Bowie with the southern Anne Arundel County communities of Davidsonville and Edgewater and several beach villages along the Chesapeake Bay. The highway connects Interstate 95 and I-495 (Capital Beltway) to FedEx Field, Six Flags America, and several stations of the Washington Metro's Blue Line, which the route parallels between Capitol Heights and Largo. MD 214 was constructed as part of three state highways. MD 214 proper was constructed in the mid-1910s from Washington to Largo and extended east to what is now U.S. Route 301 (US 301) through the 1920s. MD 254 was built from MD 2 in Edgewater west to Davidsonville in the early to mid-1920s. MD 253 was constructed from the modern end of the highway southeast to Beverly Beach between the mid-1920s and early 1930s. The gap between Bowie and Davidsonville was filled in the mid-1930s; MD 214 was extended east across a new Patuxent River bridge and took over MD 254's route to Edgewater. In the late 1940s, MD 214 was relocated through Edgewater and extended along most of MD 253 to Beverly Beach. The state highway was widened in Prince George's County in the 1930s and again in the 1950s, and from US 301 to MD 2 in the 1940s and again in the 1950s. MD 214 was expanded to a divided highway at US 301 in the late 1950s, at its interchange with the Capital Beltway in the mid-1960s, and when it bypassed Capitol Heights in the late 1960s. The two-lane gaps between those three segments were filled in the 1980s and 1990s. ==Route description== MD 214 begins at East Capitol Street's intersection with Southern Avenue at the District of Columbia boundary in Capitol Heights. This junction is a short distance southwest of the eastern corner of Washington and adjacent to the Capitol Heights Metro station. MD 214 heads east as a six-lane divided highway along the northern edge of the town of Capitol Heights and crosses Henson Creek. The highway begins to follow the southern city limit of Seat Pleasant at its intersection with unsigned MD 332A, which provides full access to MD 332 (Central Avenue). MD 214's name changes to Central Avenue where the eastbound lane of MD 332 (Old Central Avenue) merges into eastbound MD 214. Just east of MD 332, the highway intersects Addison Road and passes the eponymous Metro station.〔〔 MD 214 intersects Morgan Boulevard—which leads north to the namesake Metro station and FedEx Field, the home of the Washington Redskins—west of its partial cloverleaf interchange with the Capital Beltway in Largo. East of the freeway, the state highway has a partial interchange with Harry S. Truman Drive, which is unsigned MD 202C and leads to Largo Town Center, which is the eastern terminal of Metro's Blue Line. The interchange includes a two-lane loop ramp from eastbound MD 214 to Harry S. Truman Drive; access from the north–south crossroad to westbound MD 214 is via a ramp that merges with one of the straight ramps at MD 214's partial cloverleaf interchange with MD 202 (Largo Road). There is no direct access from westbound MD 214 to southbound MD 202 or from northbound MD 202 to eastbound MD 214; those movements are made via Campus Way to the east of the interchange.〔〔 MD 214 continues east between the suburbs of Lake Arbor to the north and Kettering to the south. East of the Western Branch of the Patuxent River, the highway intersects MD 193, which heads north as Enterprise Road and south as Watkins Park Drive. MD 214 reduces to four lanes and passes along the southern edge of Six Flags America. East of Church Road, the highway enters the southern fringe of the city of Bowie. At Devonwood Drive, which is unsigned MD 978C, MD 214 veers southeast and parallels Hall Road, which is MD 978A. The highways both intersect CSX's Popes Creek Subdivision rail line and cross Collington Branch before the roads reunite. MD 978B (Old Central Avenue) splits to the southeast ahead of MD 214's partial cloverleaf interchange with US 301 (Robert Crain Highway), then rejoins the main road east of the interchange. Access from eastbound MD 214 to southbound US 301 and from northbound US 301 to eastbound MD 214 is via Old Central Avenue. At the eastern junction with the old road, MD 214 drops to two lanes.〔〔 MD 214 intersects Queen Anne Bridge Road, which leads to the abandoned Queen Anne Bridge and the historic home Hazelwood, just west of its steel through truss bridge across the Patuxent River at the Prince George's–Anne Arundel county line. The highway meets the southern end of MD 424 (Davidsonville Road) in the Davidsonville Historic District. MD 214 intersects Riva Road and passes the historic home Summer Hill on its way to Edgewater. The highway gains a second lane westbound at Pike Ridge Road, which is unsigned MD 214A. The route gains a second eastbound lane and a median just west of its intersection with MD 2 (Solomons Island Road). MD 214 veers southeast and becomes undivided at Stepneys Lane and meets the southern end of MD 253 (Mayo Road) opposite South River High School, then drops to two lanes ahead of its intersection with MD 468 (Muddy Creek Road). MD 214 continues east through the community of Selby-on-the-Bay, where it passes the entrance to Camp Letts and the historic home Gresham. The highway passes through Mayo and its name changes to Beverly Avenue on the northern edge of Beverly Beach. MD 214 curves east onto Grande View Avenue and reaches its eastern terminus at a gate just east of Oakford Avenue.〔〔 MD 214 is a part of the National Highway System as an intermodal connector between the Addison Road Metro station and the Capital Beltway. The highway is a National Highway System principal arterial from Southern Avenue to the Addison Road Metro station, from the Capital Beltway to US 301, and from Vicksburg Road near Davidsonville to Shoreham Beach Road in Beverly Beach.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Maryland Route 214」の詳細全文を読む スポンサード リンク
