Capital Beltway in the context of "Highway spur"

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.

Interstate 95 (I-95) runs 179 miles (288 km) within the commonwealth of Virginia between its borders with North Carolina and Maryland. I-95 meets the northern terminus of I-85 in Petersburg and is concurrent with I-64 for three miles (4.8 km) in Richmond. Although I-95 was originally planned as a highway through Washington, D.C. (following the route of what is now I-395), it was rerouted along the eastern portion of the Capital Beltway concurrent with I-495. From Petersburg to Richmond, I-95 utilized most of the Richmond–Petersburg Turnpike, a former toll road (the south end of the toll road was on I-85). In addition to Richmond, the route also runs through the medium-sized cities of Emporia, Petersburg, Colonial Heights, Fredericksburg, and Alexandria.

It enters the Capital Beltway at the Springfield Interchange, also known as the Mixing Bowl. I-95 continues over the Potomac River on the Woodrow Wilson Bridge into Washington, D.C. (for 0.11 miles [0.18 km] on the bridge) and then into Maryland on the Capital Beltway.

Silver Spring is a census-designated place (CDP) in southeastern Montgomery County, Maryland, United States, near Washington, D.C. Although officially unincorporated, it is an edge city with a population of 81,015 at the 2020 census, making it the fifth-most-populous place in Maryland after Baltimore, Columbia, Germantown, and Waldorf.

Downtown Silver Spring, located next to the northern tip of Washington, D.C., is the oldest and most urbanized area of Silver Spring, surrounded by several inner suburban residential neighborhoods inside the Capital Beltway. Many mixed-use developments combining retail, residential, and office space have been built since 2004.

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 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.

Interstate 95 (I-95) is an interstate highway running along the East Coast of the United States from Miami, Florida, north to the Canadian border in Houlton, Maine. In Maryland, the route is a major highway that runs 110.0 miles (177.0 km) diagonally from southwest to northeast, entering from Washington, D.C. and Virginia at the Woodrow Wilson Bridge over the Potomac River, northeast to the Delaware state line near Elkton. It is the longest Interstate Highway within Maryland and is one of the most traveled Interstate Highways in the state, especially between Baltimore and Washington, D.C., despite alternate routes along the corridor, such as the Baltimore–Washington Parkway, US 1, and US 29. I-95 also has eight auxiliary routes in the state, the most of any state along the I-95 corridor. Portions of the highway, including the Fort McHenry Tunnel and the Millard E. Tydings Memorial Bridge, are tolled.

From the Woodrow Wilson Bridge to the community of College Park, it follows a portion of the Capital Beltway, completed in 1964 and numbered as I-95 in 1977. Prior to 1977, the route was intended to go on a new highway through Washington, D.C.; however, public opposition caused the cancelation of I-95 inside of the Capital Beltway. The unnamed section between the Capital Beltway to north of Baltimore was completed in various stages between 1964 and 1985, while the northeastern section from Baltimore to the Delaware state line, known as the John F. Kennedy Memorial Highway (named after the former US president, John F. Kennedy), was the first section completed, opening to traffic in 1963. A rebuild of this section was begun in 2006, and is underway; as of 2022, several miles of express toll lanes have been added to I-95 north of Baltimore, with further widening of the roadway planned through to the Delaware state line.

The Springfield Interchange, also known as the Mixing Bowl, is the interchange of I-95, I-395, and the Capital Beltway I-495 in Springfield, Virginia, outside of Washington, D.C. The interchange is located at exit 57 on the Capital Beltway, exit 170 on I-95, and exit 1 on I-395.

Some people, including many Washington-area media sources, refer to this interchange as the "Mixing Bowl" because, prior to the reconstruction, local and long-distance travelers shared the same lanes and travelers had to merge to the right or left to reach the correct lanes for their destination. The last of this weaving and merging was eliminated on April 21, 2007.
