'Interstate 170' (abbreviated 'I-170') is the designation for an interstate route in the St. Louis, Missouri metropolitan area. I-170, also known as the 'Inner Belt Expressway', is an 11.17 mile highway traveling north-south through the St. Louis suburbs of Hazelwood, Berkeley, St. John, Charlack, Vinita Park, Sycamore Hills, Bel-Ridge, Olivette,Overland, University City, Ladue, Clayton, and Richmond Heights, ending just north of the city of Brentwood.

History


I-170 was originally intended to provide an inner beltway within I-270 through St. Louis County extending to I-55 in the South County area; however, the portion of the route south of I-64/U.S. 40 was cancelled due to local opposition. The portion of Metrolink's Cross County Extension south of I-64 runs roughly along the proposed alignment.
The southern portion of I-170 was built using St. Louis County funds in the 1960s. It was signed as Route 725.

Future prospects


The southern two interchanges on I-170 (at I-64/U.S. 40 and Galleria Parkway) are to be reconstructed as part of the New I-64 project beginning in 2007. Most notably, the new interchange will include direct access to I-170 from eastbound I-64; however, access to Galleria Parkway from northbound I-170 will be eliminated.[2]
