Interstate 95 in Maryland

Interstate 95 (I-95) is an Interstate Highway running along the East Coast of the United States from Miami, Florida, north to the Canada–United States border at Houlton, Maine. In Maryland, the route is a major highway that runs 110.01 miles (177.04 km) diagonally from southwest to northeast, entering from the District of Columbia and Virginia at the Woodrow Wilson Bridge over the Potomac River, northeast to Maryland's border with Delaware near Elkton. It is the longest Interstate Highway within Maryland and is one of the most traveled Interstate Highways in the state, especially between Baltimore and Washington, D.C., despite alternate routes along the corridor, such as the Baltimore–Washington Parkway, U.S. Route 1 (US 1), and US 29. I-95 also has eight auxiliary routes in the state, the most of any state along the I-95 corridor. Portions of the highway, including the Fort McHenry Tunnel and the Millard E. Tydings Memorial Bridge, are tolled.

From the Woodrow Wilson Bridge to the community of College Park, it follows a portion of the Capital Beltway, completed in 1964 and numbered as I-95 in 1977. Prior to 1977, the route was intended to go on a new highway through Washington, D.C.; however, public opposition caused the cancelation of I-95 inside of the Capital Beltway. The unnamed section between the Capital Beltway to north of Baltimore was completed in various stages between 1964 and 1985, while the northeastern section from Baltimore to the Delaware state line, known as the John F. Kennedy Memorial Highway (named after the former US president, John F. Kennedy), was the first section completed, opening to traffic in 1963. A rebuild of this section was begun in 2006, and is underway; as of 2022, several miles of express toll lanes have been added to I-95 north of Baltimore, with further widening of the roadway planned through to the Delaware state line.
