Interstate 95 in Maryland in the context of "Fort McHenry Tunnel"

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 24.97 miles (40.19 km) from Southern Avenue and East Capitol Street at the District of Columbia boundary in Capitol Heights east to Beverley 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 (I-95)/I-495 (Capital Beltway) to Northwest Stadium, Six Flags America, and several stations of the Washington Metro's Blue and Silver lines, 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 Beverley 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 Beverley 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.

Locust Point is a peninsular neighborhood in Baltimore, Maryland. Located in South Baltimore, the neighborhood is entirely surrounded by the Locust Point Industrial Area; the traditional boundaries are Lawrence street to the west and the Patapsco River to the north, south, and east. It once served as a center of Baltimore's Polish-American, Irish-American and Italian-American communities; in more recent years Locust Point has seen gradual gentrification with the rehabilitation of Tide Point and Silo Point. The neighborhood is also noted as being the home of Fort McHenry and the western end of its namesake tunnel that carries eight lanes of Interstate 95 under the river.

Locust Point has been called "Baltimore's Ellis Island" because the neighborhood was once the third largest point of entry for immigrants to the United States after Ellis Island and the Port of Philadelphia. From 1868 until the closure of the Locust Point piers in 1914, 1.2 million European immigrants entered Baltimore through Locust Point.

Maryland Route 4 (MD 4) is a state highway in the U.S. state of Maryland. The highway runs 64.85 miles (104.37 km) from MD 5 in Leonardtown north to Southern Avenue in Suitland at the District of Columbia boundary, beyond which the highway continues into Washington as Pennsylvania Avenue. MD 4 is a four- to six-lane highway that connects Washington and communities around Interstate 95 (I-95)/I-495 (Capital Beltway) with southern Prince George's County with southwestern Anne Arundel County. The highway is the primary highway for the length of Calvert County, during most of which the route runs concurrently with MD 2. MD 4 also connects Calvert and St. Mary's counties via the Governor Thomas Johnson Bridge across the Patuxent River. The highway connects the Southern Maryland county seats of Leonardtown, Prince Frederick, and Upper Marlboro.

MD 4 is one of the original Maryland state highways. The state highway followed roughly its present alignment through Prince George's County, then headed east through Anne Arundel County along what is now MD 408. In the 1960s, MD 4 took over MD 416 (Southern Maryland Boulevard) southeast to Sunderland and joined MD 2 all the way to Solomons. After the Governor Thomas Johnson Bridge opened in the late 1970s, MD 4 was extended west from Solomons to Leonardtown. MD 4 has been upgraded to a divided highway for most of its length, beginning in the early 1960s from Washington, reaching Solomons in the mid-1980s, and expected to continue into St. Mary's County in the future.

Maryland Route 210 (MD 210) is a state highway in the U.S. state of Maryland. Known as Indian Head Highway, the highway runs 20.86 miles (33.57 km) from Potomac Avenue in Indian Head north to the District of Columbia boundary in Forest Heights, where the highway continues into Washington, D.C., as South Capitol Street. MD 210 is a four- to six-lane divided highway that connects Washington, D.C., with the suburban communities of Oxon Hill, Fort Washington, and Accokeek in southwestern Prince George's County, and Bryans Road and Indian Head in northwestern Charles County. The highway also provides access to Fort Washington Park and Indian Head Naval Surface Warfare Center and, in conjunction with MD 228, connects Waldorf with Interstate 95 (I-95)/I-495 and I-295.

Indian Head Highway was constructed by the U.S. federal government as a military access highway in the mid-1940s to connect Washington with the Indian Head Naval Proving Ground and Fort Washington. The previous highway between Washington, D.C., and Indian Head was Livingston Road, which was traced in the late 18th century and improved in the 1920s and early 1930s as MD 224. The new highway incorporated several sections of meandering MD 224 into its straight path. Indian Head Highway was fully designated MD 210 in the mid-1950s when the road was transferred from federal to state control. MD 210 was expanded to a divided highway in Forest Heights in the late 1940s and south through Fort Washington in the 1960s. Another section of divided highway was completed through Charles County in the late 1960s and early 1970s. The final divided highway section was completed through Accokeek in the mid-1980s. MD 210 was connected with I-295 in 1989 and its interchange with I-95/I-495 was reconstructed in the mid-2000s. The Maryland State Highway Administration has long-term plans to replace the highway's major intersections with interchanges from Oxon Hill south through Fort Washington.

Interstate 295 (I-295) also known as the Anacostia Freeway, is a six-mile (9.7 km) auxiliary Interstate Highway in the US state of Maryland and in Washington, D.C. It connects I-95/I-495 and Maryland Route 210 (MD 210; Indian Head Highway) near the Potomac River (just outside DC's boundary with Maryland) to I-695 and District of Columbia Route 295 (DC 295) in the Anacostia neighborhood of Washington, D.C.

Maryland Route 201 (MD 201) is a state highway in the U.S. state of Maryland. Known for most of its length as Kenilworth Avenue, the highway runs 9.40 miles (15.13 km) from the District of Columbia boundary in Tuxedo, where the highway continues south as District of Columbia Route 295 (DC 295), north to MD 212 in Beltsville. MD 201 is a four to six-lane divided highway that connects Washington, D.C., with the northern Prince George's County municipalities of Cheverly, Bladensburg, Edmonston, Riverdale Park, College Park, Berwyn Heights, and Greenbelt. The highway also provides part of the connections from Interstate 95 (I-95)/I-495 to a pair of Washington Metro stations. MD 201 was built as two separate highways in the late 1920s: MD 201 from Washington, D.C., to Bladensburg and MD 205 from Bladensburg to Greenbelt. These highways, some of which became MD 769, were replaced with a relocated Kenilworth Avenue in the mid 1950s, including the Kenilworth Interchange with U.S. Route 50 (US 50) and the Baltimore–Washington Parkway in Tuxedo. MD 201 was extended north to Beltsville in the early 1960s. The Maryland State Highway Administration (MDSHA) plans to extend MD 201 north toward Laurel.

The Baltimore–Washington Parkway (also referred to as the B–W Parkway) is a controlled-access parkway in the U.S. state of Maryland, running southwest from Baltimore to Washington, D.C. The road begins at an interchange with U.S. Route 50 (US 50) near Cheverly in Prince George's County at the Washington, D.C., border, and continues northeast as a parkway maintained by the National Park Service (NPS) to MD 175 near Fort Meade, serving many federal institutions. This portion of the parkway is dedicated to Gladys Noon Spellman, a representative of Maryland's 5th congressional district, and has the unsigned Maryland Route 295 (MD 295) designation. Commercial vehicles, including trucks, are prohibited within this stretch. This section is administered by the NPS's Greenbelt Park unit. After leaving park service boundaries the highway is maintained by the state and signed with the MD 295 designation. This section of the parkway passes near Baltimore–Washington International Thurgood Marshall Airport.

Upon entering Baltimore, the Baltimore Department of Transportation takes over maintenance of the road and it continues north to an interchange with Interstate 95 (I-95). Here, the Baltimore–Washington Parkway ends and MD 295 continues north unsigned on Russell Street, which carries the route north into downtown Baltimore. In downtown Baltimore, MD 295 follows Paca Street northbound and Greene Street southbound before ending at US 40.
