U.S. Route 1 in the context of "George Washington Bridge"

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, north 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, Georgia, and Washington, D.C., and the portion between Portland and Houlton in Maine, both of which follow a more direct inland route.

I-95 serves as the principal road link between the major cities of the Eastern Seaboard. Major metropolitan areas along its route include Miami, Jacksonville, and Savannah in the Southeast; Richmond, Washington, Baltimore, Wilmington–Philadelphia, Newark, and New York City in the Mid-Atlantic; and New Haven, Providence, Boston, and Portland in New England. The Charleston, Wilmington, and Norfolk–Virginia Beach metropolitan areas, the three major coastal metros bypassed by the highway's inland portion, are connected to I-95 by I-26, I-40, and I-64, respectively.

Potomac Yard is a neighborhood in Northern Virginia that straddles southeastern Arlington County and northeastern Alexandria, Virginia, located principally in the area between U.S. Route 1 and the Washington Metro Blue Line /Yellow Line tracks, or the George Washington Memorial Parkway, depending on the definition used. The area was home to (and takes its name from) what was once one of the busiest rail yards on the Eastern Seaboard of the United States. The "Potomac Yard" name is also used to refer to several developments in the area, especially the Potomac Yard Center power center and a Washington Metro station.

In 2018, Amazon.com, Inc. announced plans to locate part of its "HQ2" second headquarters project in Northern Virginia, specifically in the newly re-branded cross-jurisdictional neighborhood of National Landing, which local and state officials said would include Potomac Yard as well as nearby parts of southern Arlington, including the Crystal City neighborhood that will be the hub of the HQ2 development. Amazon initially planned to split HQ2 between National Landing and Long Island City, New York, but opposition from New York officials led Amazon to cancel that portion of the project, leaving National Landing as the only HQ2 site.

U.S. Route 13 or U.S. Highway 13 (US 13) is a north–south United States Numbered Highway established in 1926 that runs for 518 miles (834 km) from Interstate 95 (I-95) just north of Fayetteville, North Carolina, to US 1 in the northeastern suburbs of Philadelphia, Pennsylvania, near Morrisville. In all, it traverses five states in the Atlantic coastal plain region. It follows the Atlantic coast more closely than does the main north–south U.S. Highway of the region, US 1. Because of this, its number is out of place on the general U.S. Highway numbering grid, as it should be running west of US 11 but does not. Its routing is largely rural, the notable exceptions being the Hampton Roads area in Virginia and the northern end of the highway in Delaware and Pennsylvania. It is also notable for being the main thoroughfare for the Delmarva Peninsula and carrying the Chesapeake Bay Bridge–Tunnel to it in Virginia.

US 13's original plan in 1926 had the route serve no further south than the Delmarva Peninsula. However, it has been extended many times, connecting to the mainland via ferry service and eventually reaching North Carolina. This link across the mouth of the Chesapeake Bay became fixed in 1964 with a bridge–tunnel. The entire route on the Delmarva Peninsula, except for a few sections in Accomack County, Virginia, has been dualized fully with four lanes, and further upgrades continue, such as a freeway section around the east side of Salisbury, Maryland.

The 14th Street bridges are a set of adjacent five road and rail bridges that cross the Potomac River, connecting Arlington, Virginia and Washington, D.C. A major gateway for automotive, bicycle and rail traffic, the bridge complex is named for 14th Street (U.S. Route 1), which feeds automotive traffic into it on the D.C. end.

The complex contains three four-lane automobile bridges—including, from west to east, one southbound, one bi-directional, and one northbound—that carry Interstate 395 (I-395) and U.S. Route 1 (US 1) traffic, as well as a bicycle and pedestrian lane on the southbound bridge. In addition, the complex contains two rail bridges, one of which carries the Yellow Line of the Washington Metro; the other of which, the only mainline rail crossing of the Potomac River to Virginia, carries a CSX Transportation rail line. The five bridges, from west to east are the George Mason Memorial Bridge, the Rochambeau Bridge, the Arland D. Williams, Jr. Memorial Bridge, the Charles R. Fenwick Bridge and the Long Bridge. In aerial photos, shadows caused by a large, concrete divider on the bi-directional Rochambeau Bridge create the illusion of two, two-lane bridges, but this is in fact, a single, four-lane structure.

Rhode Island Avenue is a diagonal avenue in the Northwest and Northeast quadrants of Washington, D.C., and the capital's inner suburbs in Prince George's County, Maryland. Paralleling New York Avenue, Rhode Island Avenue was one of the original streets in Pierre L'Enfant's plan for the capital. It became a major commuter route, carrying U.S. Route 1 traffic into the city from Prince George's County.

The western terminus of Rhode Island Avenue is in downtown Washington, at an intersection with Connecticut Avenue NW and M Street NW. The Cathedral of St. Matthew the Apostle is on Rhode Island Avenue NW, just east of that intersection. Just east of the cathedral, at Scott Circle, Rhode Island Avenue NW intersects Massachusetts Avenue NW and 16th Street NW. N Street NW stops short of meeting the circle from either direction, but is instead connected to Rhode Island and Massachusetts avenues NW through two short streets, Corregidor Street NW and Bataan Street NW. From Scott Circle, Rhode Island Avenue NW continues eastward to the Logan Circle neighborhood. At the traffic circle of the same name, Rhode Island Avenue NW intersects Vermont Avenue, 13th Street, and P Street NW.
