At Valley Forge, northwest of Philadelphia, I-76 leaves the Turnpike to run into Philadelphia on the Schuylkill Expressway (while the Turnpike continues east as I-276). Immediately after exiting the Turnpike, I-76 interchanges with the US 202 and US 422 freeways near King of Prussia. I-76 later crosses I-476 near Conshohocken, and begins running along the southwest shore of the Schuylkill River. I-76 then enters the city/county limits of Philadelphia where Interchanges provide access to the Roosevelt Expressway (US 1) and the Vine Street Expressway (I-676); the latter runs through Downtown Philadelphia while I-76 bypasses to the south.
