Capital Beltway

The Capital Beltway is a 64-mile (103 km) Interstate Highway in the Washington metropolitan area 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. 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.

This circumferential roadway is located not only in the states of Maryland and Virginia, but also crosses briefly (for about 300 feet [91 m]) through the District of Columbia, near the western end of the Woodrow Wilson Bridge over the Potomac River. The Beltway passes through Prince George's County and Montgomery County in Maryland, and Fairfax County and the independent city of Alexandria in Virginia.

The Cabin John Parkway, a short connector between I-495 and the Clara Barton Parkway near the Potomac River along the Maryland–Virginia border, is considered an Interstate spur (I-495X) by the Maryland State Highway Administration.
