Maryland Route 2 Truck is a truck bypass of the Federal Hill neighborhood south of downtown Baltimore, Maryland, United States.
The route runs east from MD 2 (Hanover Street) on McComas Street, paralleling I-95.
From McComas Street, at exit 55 of Interstate 95 just west of the Fort McHenry Tunnel, the route continues onto Key Highway and heads north and west to Light Street (MD 2), mostly paralleling the Northwest Harbor and serving the piers on the harbor.

The road was laid out to a width of 160 feet (50 m) from Light Street to Locust Point in the early 1910s, providing better access to the new city-owned piers in preparation for increased trade via the Panama Canal and existing steamship lines to Europe.
It was named Key Highway because it was originally planned to extend to Fort McHenry, near where Francis Scott Key wrote "The Star-Spangled Banner."
However, the extension of the road to the fort was never built.
A rail line ran the length of Key Highway, connecting to the tracks in Pratt Street via Light Street.
A two-lane extension of the highway and rail line was built in 1930, branching off the old route east of Ludlow Street and running south under Fort Avenue to McComas Street.
The short portion of the old road east of the extension is now East Key Highway; the rail tracks have been removed.
