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 (MD 4) and then MD Route 717 in Upper Marlboro, and finally Stephanie Roper Highway.

The section of the avenue between the White House (which is sometimes referred to by its address, "1600 Pennsylvania Avenue") and Congress forms the basis for the Pennsylvania Avenue National Historic Site and is sometimes referred to as "America's Main Street";^[1] it is the location of official parades and processions, and periodic protest marches. Pennsylvania Avenue is an important commuter road and is part of the National Highway System.^[2]^[3]
