Interstate 95, the most significant highway on the U.S. East Coast, is a major thoroughfare for Maryland. Connecting the Baltimore and Washington metropolitan areas, it has four distinct segments within the state: 27 miles of the Washington area's Capital Beltway with Interstate 495, a segment between the Capital and Baltimore beltways, one through Baltimore itself, and the John F. Kennedy Memorial Highway, running from the eastern edge of Baltimore to the Delaware line. I-95 has tolls at the Fort McHenry Tunnel in Baltimore as well as the Cecil County side of the Tydings Bridge over the Susquehanna River. No part of I-95 within Maryland is less than three lanes in each direction, and 13 miles of it between east Baltimore and the Joppa area of Harford County contain express lanes in the median.
