U.S. Route 1 or U.S. Highway 1 (US 1) is a major north–south United States Numbered Highway that serves the East Coast of the United States. It runs 2,369 miles (3,813 km), from Key West, Florida north to Fort Kent, Maine, at the Canadian border, making it the longest north–south road in the United States. US 1 is generally paralleled by Interstate 95 (I-95), though the former is significantly farther west (inland) between Jacksonville, Florida, and Petersburg, Virginia. The highway connects most of the major cities of the East Coast—including Miami, Jacksonville, Raleigh, Richmond, Washington, D.C., Baltimore, Philadelphia, New York City, and Boston passing from the Southeastern United States to New England.
Interstate 95 (I-95) is the main north–south Interstate Highway on the East Coast of the United States, running from U.S. Route 1 (US 1) in Miami, Florida to the Houlton–Woodstock Border Crossing between Maine and the Canadian province of New Brunswick. The highway largely parallels the Atlantic coast and US 1, except for the portion between Savannah and Washington and the portion between Portland and Houlton, both of which follow a more direct inland route.
The Baltimore–Washington Parkway is a highway 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.
Interstate 295 is the designation for several Interstate Highways in the United States:
The Capital Beltway is a 64-mile (103 km) Interstate Highway that surrounds Washington, D.C., the capital of the United States, and its inner suburbs in adjacent Maryland and Virginia. It is the basis of the phrase "inside the Beltway", used when referring to issues dealing with U.S. government and politics. The highway is signed as Interstate 495 (I-495) for its entire length, and its southern and eastern half runs concurrently with I-95.
Maryland Route 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, north to MD 212 in Beltsville. MD 201 is a four to six-lane divided highway that connects Washington 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 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 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.
District of Columbia Route 295 (DC 295), also known as the Anacostia Freeway as well as the Kenilworth Avenue Freeway north of East Capitol Street, is a freeway in the District of Columbia, and currently the only signed numbered route in the District that is not an Interstate Highway or U.S. Highway. Also, DC 295 is one of the few city-level signed route numbers in the United States, along with Charlotte Route 4. The south end is at the junction of Interstate 295 (I-295), I-695, and the southern end of the 11th Street Bridges; its north end is at the border with Maryland where it continues as Maryland Route 201 (MD 201) and then the Baltimore–Washington Parkway.
Interstate 295 (I-295) in Delaware, New Jersey, and Pennsylvania is an auxiliary Interstate Highway, designated as a bypass around Philadelphia and a partial beltway of Trenton, New Jersey. The route begins at a junction with I-95 south of Wilmington, Delaware, and runs to an interchange with I-95 in Bristol Township, Pennsylvania. The highway heads east from I-95 and crosses the Delaware River into New Jersey on the Delaware Memorial Bridge concurrent with U.S. Route 40 (US 40). Upon entering New Jersey, I-295 splits from the New Jersey Turnpike and US 40, and runs parallel to the turnpike for most of its course in the state. After a concurrency with US 130 in Gloucester County, I-295 has an interchange with I-76 and Route 42 in Camden County. The freeway continues northeast toward Trenton, where it intersects I-195 and Route 29 before bypassing the city to the east, north, and west, crossing the Delaware River on the Scudder Falls Bridge into Pennsylvania. In Pennsylvania, I-295 is signed as an east–west road and heads south to its other terminus at I-95. I-295 is one of two three-digit interstates in the United States to enter three states, with the other one being the I-275 beltway around Cincinnati which enters Ohio, Indiana, and Kentucky.
Interstate 295 (I-295) in the U.S. state of Maryland and in Washington, D.C., also known as the Anacostia Freeway, is a 8.05-mile (12.96 km) spur route connecting I-95 / I-495 and Maryland Route 210 near the Potomac River to Interstate 695 and D.C. Route 295 in the Anacostia neighborhood of Washington, D.C.
Interstate 395 (I-395) in Washington, D.C., and Virginia is a 13.39-mile-long (21.55 km) spur route of I-95 that begins at an interchange with I-95 in Springfield and ends at an interchange with U.S. Route 50 in northwest Washington, D.C. It passes underneath the National Mall near the U.S. Capitol and ends at a junction with US 50 at New York Avenue, roughly one mile (1.6 km) north of the 3rd Street Tunnel. Despite its proximity to I-395 in Maryland, the route is unrelated and unconnected.
Interstate 195 (I-195) is an Interstate highway in the U.S. state of Maryland. The highway runs 4.35 miles (7.00 km) from I-95 in Arbutus east to MD 170 near the Baltimore/Washington International Thurgood Marshall Airport in Linthicum. I-195, which is also known as Metropolitan Boulevard, is the main connection between the airport terminal and highways leading to Baltimore, Washington, and Annapolis, including I-95, MD 295, and I-97. The interchange with MD 170, which forms part of the Airport Loop, provides access to various airport-related services. I-195 also links I-95 with Catonsville and the University of Maryland, Baltimore County (UMBC), via a westward continuation of Metropolitan Boulevard that is part of MD 166.
Interstate 695 (I-695) is a 2-mile-long (3.2 km) auxiliary Interstate Highway in Washington, D.C.. It is also known as the Southeast Freeway. It travels from an interchange with I-395 south of the United States Capitol building east then south across the 11th Street Bridges to an intersection with I-295 and District of Columbia Route 295 (DC 295) in Anacostia.
Interstate 270 (I-270) is a 34.70-mile (55.84 km) auxiliary Interstate Highway in the U.S. state of Maryland that travels between I-495 just north of Bethesda in Montgomery County and I-70 in the city of Frederick in Frederick County. It consists of the 32.60-mile (52.46 km) mainline as well as a 2.10-mile (3.38 km) spur that provides access to and from southbound I-495. I-270 is known as the Washington National Pike, and makes up the easternmost stretch of the Dwight D. Eisenhower Highway. Most of the southern part of the route in Montgomery County passes through suburban areas around Rockville and Gaithersburg that are home to many biotech firms. This portion of I-270 is up to twelve lanes wide and consists of a local-express lane configuration as well as high-occupancy vehicle lanes that are in operation during peak travel times. North of the Gaithersburg area, the road continues through the northern part of Montgomery County, passing Germantown and Clarksburg as a six- to eight-lane highway with an HOV lane in the northbound direction only. North of here, I-270 continues through rural areas into Frederick County and toward the city of Frederick as a four-lane freeway.
The 11th Street Bridges are a complex of three bridges across the Anacostia River in Washington, D.C., United States. The bridges convey Interstate 695 across the Anacostia to its southern terminus at Interstate 295 and DC 295. The bridges also connect the neighborhood of Anacostia with the rest of the city of Washington.
The Inner Loop was two planned freeways around downtown Washington, D.C. The innermost loop would have formed an oval centered on the White House, with a central freeway connecting the southern segment to the northern segment and then continuing on to Interstate 95. Interstate 95 would have met Interstate 66, Interstate 295, Interstate 695, and US 50 while traversing the Inner Loop. A second loop was an arc across the northern section of the city, beginning at East Capitol Street at the Anacostia River and using the Missouri Avenue NW and Nebraska Avenue NW commercial corridors to terminate in Georgetown.
Interstate 95 (I-95) in Maryland is a major highway that runs 109.01 miles (175.43 km) diagonally from northeast to southwest, from Maryland's border with Delaware, to the Woodrow Wilson Bridge, entering the District of Columbia and reaching Virginia. The route is one of the most traveled Interstate Highways in Maryland, especially between Baltimore and Washington, D.C., despite alternate routes along the corridor, such as the Baltimore-Washington Parkway, U.S. Route 1, and US 29. Portions of the highway, including the Fort McHenry Tunnel, are tolled.
The streets and highways of Washington, D.C., form the core of the city's surface transportation infrastructure. Given that it is a planned city, streets in the capital of the United States follow a distinctive layout and addressing scheme. There are 1,500 miles (2,400 km) of public roads in the city, of which 1,392 miles (2,240 km) are owned and maintained by the district government.
U.S. Route 50 (US 50) is a major east–west route of the U.S. Highway system, stretching just over 3,000 miles (4,800 km) from Ocean City, Maryland, on the Atlantic Ocean, to West Sacramento, California, nearly to the Pacific Ocean. In the District of Columbia, US 50 passes between Arlington County, Virginia, and Prince George's County, Maryland, predominantly along surface streets, including a part of Constitution Avenue along the National Mall.
U.S. Route 29 is a north–south United States highway that runs for 1,036 miles (1,667 km) from the western suburbs of Baltimore, Maryland, to Pensacola, Florida. In the U.S. state of Maryland, US 29 is a major highway that emerges from Washington, D.C., and runs north into eastern Montgomery County, stretching over 25.859 miles (41.62 km) through the state and terminating at Maryland Route 99 outside of Ellicott City. It serves the cities of Columbia and Ellicott City and provides the westernmost north–south route between Washington, D.C., and Baltimore.
