Now marked only as US-40.

Was to be the grand entrance of I-70 into Baltimore and a fitting end to a nearly transcontinental route, and later to be a spur of I-70. The quintessential Lost Freeway of Baltimore.

A 1.39 mile section of I-170 was begun in 1975 and completed in 1979. It was an ambitious project, a depressed roadway with space in the median for a rail or subway corridor. Hundreds of houses, all those in the corridor between Franklin and Mulberry Streets were condemned and razed.

Vehement neighborhood opposition would eventually kill the I-70 extension through Leakin Park in West Baltimore to link with the completed 170. I-70 now ends at a park & ride at the city line. South of 170, the part of 70 that would have connected with I-95 just east of Caton Ave. was also killed. The I-170 designation was dropped in 1989, and signed as US-40.
