A truck bypass of Baltimore's US 40 was signed in 1960 to take through
truck traffic around Baltimore's downtown/Inner Harbor area. The truck
route diverges from US 40 at Hilton Street and follows the Hilton
Parkway, North Avenue (US 1), Bel Air Road (US 1), and Erdman Avenue
(MD 151) to meet US 40 again. Little green signs guide traffic along
the route's few turns, but reassurance markers for Truck US 40 are
nowhere to be found along the route. Nonetheless, at each US 40 interchange
and the I-83 interchange, Truck US 40 is clearly signed.

The second exit at the US 40 interchange is for both US 40 east and
the I-895 tollway. Truck US 40 east now ends as the truck route connects
back to US 40.

Now heading westbound into Baltimore along US 40. Like at I-83, Truck
US 40 is well signed on guide signs. MD 151 is probably meant for
the blank spot on the left side of the sign.

MD 151 is signed on old, faded guide signs at the Truck US 40 exit.
This is the eastern end of the Truck US 40/MD 151 duplex.

End · US 40, western Baltimore

Timothy Reichard 9/14/02
Westbound on Truck US 40/Hilton Parkway at the interchange with US
40. Hilton Parkway is a short, curvy, four-lane bypass of Hilton Street,
which connects North Avenue to Edmondson Avenue (US 40).

Timothy Reichard 9/14/02
The exit for US 40 west leads to the intersection of Hilton Street
and US 40.

Timothy Reichard 7/24/02
Eastbound on US 40 at the Truck US 40/Hilton Parkway interchange.
Truck US 1 is also implied by the overhead sign, but that route only
connects to US 1 on the north side, not qualifying for a bona fide
truck route.
