Philadelphia's highways follow its two rivers. I-95 runs along the Delaware River from the airport past South Philly, Center City and Port Richmond into the Northeast, and I-76, the Schuylkill Expressway, follows the Schuylkill River west from South Philly past University City and Manayunk toward King of Prussia. I-676, the Vine Street Expressway, cuts across Center City and over the Ben Franklin Bridge into New Jersey, and the Walt Whitman, Betsy Ross and Tacony-Palmyra bridges also cross the Delaware.
Roosevelt Boulevard, US 1, runs through North and Northeast Philadelphia as a wide, busy road with inner and outer lanes. I-476, the Blue Route, runs through the western suburbs, and the Pennsylvania Turnpike crosses the northern suburbs. Broad Street runs north and south through the heart of the city. The Schuylkill Expressway is famous for congestion, and a breakdown on its narrow shoulders is one of the worst places in the region to be stuck.
Philadelphia International Airport sits in the southwest along I-95, and SEPTA's Airport Line connects it with Center City. SEPTA's Broad Street Line and Market-Frankford Line, trolleys, buses and Regional Rail cover the city, and many Philadelphians use transit daily, which makes it easy to leave the car where it is parked while it is repaired.
For a mobile mechanic, Philadelphia is mostly rowhouse blocks with street parking. Narrow streets, double-parked trucks and permit zones shape where a repair can happen, and the mechanic plans around them. The Northeast, Chestnut Hill and parts of the far west and northwest have driveways and garages, which makes longer jobs easier.
