It's hard to believe that it's only been 12-years since the tire-fire of 1996, and the subsequent closing of I-95 for the emergency reconstruction of a not-insignificant portion. It's even more incredible to realize that the stretch that runs through Center City (and the bane of most of Center City's development worries) has only been less than 3-decades. Furthermore, the whole system wasn't effectively started until 1965, and wasn't completed until the very end of 1985 (with the completion of construction of the airport segment), costing half a billion ($500m) dollars.

Since it's quite likely you may not be making it to work (or home), and you want to get your road-on, try Wikipedia, the Philadelphia Inquirer's map suggesting alternate routes, and PhillyRoads.
With memories of the Minnesota I-35W collapse fresh in our memories, and reports of a crumbling national infrastructure, it's not a bad idea to consider the condition of the roadway (either national, state-owned, or local) passing beneath your bottom, lest you 'kiss your ass goodbye'.
Update: Philly.com has an archived interactive map displaying regional bridges and their ratings. Alas, the newspaper archives require registration.
