Pennsylvania Avenue is a primarily diagonal street in Washington, D.C. that connects the United States Capitol with the White House and then crosses northwest Washington, D.C. to Georgetown. Traveling through southeast Washington from the Capitol, it enters Prince George's County, Maryland, and becomes MD Route 4 and then MD Route 717 in Upper Marlboro, and finally Stephanie Roper Highway.

The United States Capitol, often called the Capitol or the Capitol Building, is the seat of the United States Congress, the legislative branch of the federal government. It is located on Capitol Hill at the eastern end of the National Mall in Washington, D.C. Although no longer at the geographic center of the national capital, the U.S. Capitol forms the origin point for the street-numbering system of the district as well as its four quadrants.
