Interstate 70 (I-70) is an Interstate Highway that is located in the Commonwealth of Pennsylvania in the United States. It runs east to west across the southwest part of Pennsylvania and serves the southern fringe of the Pittsburgh metropolitan area.[2]

About half of this route is concurrent with I-76 on the Pennsylvania Turnpike, which is a toll road. This is the oldest segment of I-70 in Pennsylvania, having been completed in 1940, and is only one of two segments of I-70 that are tolled, with the other being the Kansas Turnpike.[2]

I-70 is one of only a few Interstate Highways to have a traffic signal—in this case, with U.S. Route 30 (US 30) in Breezewood, where it leaves the Pennsylvania Turnpike and heads toward Maryland.[2]
