Norristown

The main east-west route to Norristown is Ridge Pike, also known as Main Street within the boundaries of Norristown and part of West Norriton Township. Ridge Pike is the same as Ridge Avenue once it enters Philadelphia. The main north-south routes are US 202, which becomes Dekalb Street once it enters Norristown northbound from King of Prussia. The alternate route is Markley Street, which runs both north- and southbound in Norristown.
