Former Interstate 170
Looking westward from the Monroe Street (U.S. 1 south) overpass at the end of the freeway built for Interstate 170 in Baltimore, Maryland. This section was demolished in 2011 and graded in 2014 for the West Baltimore MARC Station parking lots. - 01/02/2001
Interstate 170 was the planned freeway spur for Downtown Baltimore from I-70 to the west. A 1.34 mile long section of the route was constructed in the late 1970s in a residential area west of Greene/Paca Streets (MD 295). Vastly below grade, the short freeway opened amid controversy in 1979. U.S. 40 remained on the parallel couplet of Franklin and Mulberry Streets until 1983 when I-170 was formally decommissioned. Construction of the freeway hastened the urban blight of the area community. The proposed MARC Red Line was envisioned to help improve the area, but it too was eventually canceled.
The freeway for Interstate 170 west of Downtown Baltimore. The I-170 designation was removed when Interstate 70 was formally canceled within the Baltimore city limits.
When plans for I-70 through Leakin and Gwynns Falls Park were dropped in 1981, it severed the connection with Interstate 170. Construction of that freeway was canceled due to the impacts to both Gwynn Falls Park and residential areas to the east. A subsequent proposal followed to incorporate the Franklin-Mulberry Expressway into a longer spur, Interstate 595 north from I-95 at Carroll Park. When I-595 was also cancelled, U.S. 40 was realigned onto the Franklin-Mulberry Expressway.

The 1980s proposal for Interstate 595 utilized the easternmost portion of what was planned for I-70 from I-95 near Exit 51 northwest to the location where I-70/170 were to converge. This idea met public opposition as well and was dropped before any work began on July 22, 1983.<sup>2</sup>
The Interstate 595 proposal made it to the 1986 Gousha <em>Metropolitan Baltimore</em> folding map.
Looking at the western end of the Interstate 170 stub freeway from Pulaski Street. A large mural was painted on the concrete wall that was intended to support unconstructed Interstate 170.
Demolition of the freeway stub commenced September 10, 2010. The $2.5 million project razed the unused freeway elements between Pulaski and Monroe Streets. A subsequent $6 million project through summer 2011 constructed two new parking lots for the adjacent MARC West Baltimore station nearby.1
