Interstate 83 (I-83) is an Interstate Highway located in the states of Maryland and Pennsylvania in the Eastern United States. Its southern terminus is at a signalized intersection with Fayette Street in Baltimore, Maryland; its northern terminus is at I-81 near Harrisburg, Pennsylvania. I-83 runs from Downtown Baltimore north to I-695 near the northern suburb of Timonium on the Jones Falls Expressway before forming a concurrency with I-695. After splitting from I-695, the route follows the Baltimore–Harrisburg Expressway north to the border between Maryland and Pennsylvania. Upon crossing the state line, I-83 becomes the Veterans of Foreign Wars of the United States Memorial Highway and continues north through York toward the Harrisburg area. The route runs along the southern and eastern portion of the Capital Beltway that encircles Harrisburg before reaching its northern terminus.
Most of the route south of Lemoyne, Pennsylvania, is a direct replacement of U.S. Route 111 (US 111), a former spur of US 11.
