I-70 was initially envisioned to go through [[Downtown Pittsburgh]] but now goes south of it. Its originally planned route was later incorporated into [[Interstate 376|I-376]], as well as parts of I-76 and [[Interstate 79|I-79]]. I-70 also overlaps I-79 near the Pittsburgh suburb of [[Washington, Pennsylvania|Washington]] for {{convert|3|mi|km|spell=in}}.

The {{convert|38|mi|km}} of I-70 between [[Washington, Pennsylvania|Washington]] and [[New Stanton, Pennsylvania|New Stanton]] is a [[Interstate Highway standards|substandard]] section of the highway. This section of I-70 used to be [[Pennsylvania Route&nbsp;71]] (PA&nbsp;71). It is characterized by sharp curves, limited sight distance, narrow shoulders, and lack of merge lanes at interchanges. Traffic on cloverleaf ramps must weave in the right throughlane of traffic due to the lack of a third lane for entering and exiting traffic. Other on- and offramps effectively function as [[right-in/right-out]] interchanges, forcing vehicles to weave in and out of the exit lane. The speed limit on this stretch is {{convert|55|mph|km/h|abbr=on}}.

From New Stanton to [[Breezewood, Pennsylvania|Breezewood]], I-70 overlaps [[Interstate 76 (Ohio–New Jersey)|I-76]] and the [[Pennsylvania Turnpike]]. This is one of only two tolled sections of I-70 (the other is in Kansas, where the portion of the [[Kansas Turnpike]] east of Topeka is signed I-70).

Drivers on I-70 near Breezewood have to leave the freeway and travel a few blocks on [[U.S. Route 30|US&nbsp;30]] past several [[traffic-light]]s before returning to the freeway.<ref>{{cite news |first= Manuel |last= Roig-Franzia |title= The Town That Stops Traffic: Travelers Encounter Way Station as Way of Life in Breezewood |newspaper= [[Washington Post]] |date= November 22, 2001 |page= B1}}</ref> This stretch of I-70 is one of the few [[List of gaps in Interstate Highways|gaps]] on the Interstate Highway System.

I-70 continues on almost due south to the Maryland border after leaving I-76 (Pennsylvania Turnpike) at Breezewood. This section is posted at {{convert|55|mph|km/h|abbr=on}} and is heavily patrolled. After the border, it meets [[Interstate 68|I-68]]'s eastern end and turns east toward Baltimore and [[Washington DC]].
