The Arroyo Seco Parkway, also known as the Pasadena Freeway, is one of the oldest freeways built in the United States. It connects Los Angeles with Pasadena alongside the Arroyo Seco seasonal river. It is notable not only for being an early freeway, mostly opened in 1940, but for representing the transitional phase between early parkways and modern freeways. It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway. A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system.
Route 110, consisting of State Route 110 (SR 110) and Interstate 110 (I-110), is a state and auxiliary Interstate Highway in the Los Angeles metropolitan area of the US state of California. The entire route connects San Pedro and the Port of Los Angeles with Downtown Los Angeles and Pasadena. The southern segment from San Pedro to I-10 in downtown Los Angeles is signed as I-110, while the northern segment to Pasadena is signed as SR 110. The entire length of I-110, as well as SR 110 south of the Four Level Interchange with US Route 101 (US 101), is the Harbor Freeway, and SR 110 north from US 101 to Pasadena is the historic Arroyo Seco Parkway, the first freeway in the western United States.
The Capital Beltway is a 64-mile (103 km) auxiliary Interstate Highway in the Washington metropolitan area that surrounds Washington DC, 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 US federal 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.
Colonial Parkway is a 23-mile (37 km) scenic parkway linking the three points of Virginia's Historic Triangle, Jamestown, Williamsburg, and Yorktown. It is part of the National Park Service's Colonial National Historical Park. Virginia's official state classification for the parkway is State Route 90003. With portions built between 1930 and 1957, it links the three communities via a roadway shielded from views of commercial development. The roadway is toll-free, is free of semi trucks, and has speed limits of around 35 to 45 mph. As a National Scenic Byway and All-American Road, it is also popular with tourists due to the James River and York River ends of the parkway.
The Rock Creek and Potomac Parkway, informally called the Rock Creek Parkway, is a parkway maintained by the National Park Service as part of Rock Creek Park in Washington, D.C. It runs next to the Potomac River and Rock Creek in a generally north–south direction, carrying four lanes of traffic from the Lincoln Memorial and Arlington Memorial Bridge north to a junction with Beach Drive near Connecticut Avenue at Calvert Street, N.W., just south of the National Zoological Park.
The George Washington Memorial Parkway, colloquially the G.W. Parkway, is a 25-mile-long (40 km) parkway that runs along the south bank of the Potomac River from Mount Vernon, Virginia, northwest to McLean, Virginia, and is maintained by the National Park Service (NPS). It is located almost entirely within Virginia, except for a short portion of the parkway northwest of the Arlington Memorial Bridge that passes over Columbia Island within the District of Columbia.
The Theodore Roosevelt Bridge is a bridge crossing the Potomac River which connects Washington, D.C., with the Commonwealth of Virginia. The bridge crosses over Theodore Roosevelt Island, and carries Interstate 66/U.S. Route 50. The center lane in the bridge is reversible; the middle barrier is moved with a barrier transfer machine. It's operated eastbound during the morning rush hour from 6-11 am. The bridge is named in honor of Theodore Roosevelt, the 26th President of the United States.
Clara Barton Parkway is an automobile parkway in the U.S. state of Maryland and the District of Columbia. The highway runs 6.8 miles (10.9 km) from MacArthur Boulevard in Carderock, Maryland, east to Canal Road at the Chain Bridge in Washington. Clara Barton Parkway is a two- to four-lane parkway that parallels the Potomac River and the Chesapeake and Ohio Canal (C&O) in southwestern Montgomery County, Maryland, and the far western corner of Washington. The parkway provides access to the communities of Cabin John and Glen Echo and several units of the Chesapeake and Ohio Canal National Historical Park. The Maryland portion of the George Washington Memorial Parkway was constructed from Carderock past Interstate 495 (I-495) to Glen Echo in the early to mid-1960s. The parkway was proposed to continue west to Great Falls and east to Georgetown. However, these proposals never came to fruition and the parkway was extended only to the Chain Bridge in the early 1970s. The Maryland portion of the George Washington Memorial Parkway was renamed in 1989 for Clara Barton, the founder of the American Red Cross, and whose original headquarters is located in Glen Echo.
The Mount Vernon Trail (MVT) is a 17-mile (27 km) long shared use path that travels along the George Washington Memorial Parkway in Northern Virginia between Rosslyn and George Washington's home at Mount Vernon. The trail connects the easternmost portions of Arlington County, the City of Alexandria, and Fairfax County, and travels mostly on dedicated trail with a small portion on city streets. As part of U.S. Bike Route 1, the Potomac Heritage Trail and the East Coast Greenway, the MVT opened in April 1972 as a gravel path and was subsequently expanded and paved.

Little Hunting Creek is a 3.6-mile-long (5.8 km) primarily tidal tributary of the Potomac River located in Fairfax County, Virginia, not to be confused with Hunting Creek farther north. A stone-arch bridge, completed in 1931, carries traffic on the George Washington Memorial Parkway across the narrow mouth of the creek, located 96.6 miles (155.5 km) upriver from the mouth of the Potomac. The Washington family built its Mount Vernon plantation on the Potomac River along both banks of Little Hunting Creek during colonial times. The creek is bordered by residential communities in addition to the Mount Vernon property. It is a popular location for recreational fishing, and much of the wildlife characteristic of the tidal Potomac wetlands can be spotted there.
