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.I-170 connects to Interstate 270 at its northern terminus and Interstate 64 at its southern terminus; at exits 7A and 7B, I-170 crosses its parent, I-70. Interstate 170 also provides access to Lambert-St. Louis International Airport.
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; [cite news |title=Hundreds of Homes Face Razing for New Highway |last=Sutin |first=Phil |coauthors=Hopgood, Mei-Ling |date=1997-01-09 |work=
St. Louis Post-Dispatch ] however, the portion of the route south of I-64/US 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. [cite news |title=Westfall Sours On Extension of Interstate 170 |last=Sutin |first=Phil |date=1997-03-14 |work=St. Louis Post-Dispatch ]The southern portion of I-170 was built using St. Louis County funds in the 1960s. It was signed as Route 725.
Future
The southern two interchanges on I-170 (at I-64/US 40 and Galleria Parkway) are being reconstructed as part of the New I-64 project. 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.cite web|url=http://www.thenewi64.org/ProjectOverview.do|title=Project Overview|accessdate=2007-05-28|work=The New I-64|publisher=
