I would not drive anywhere near I-95 in the Philadelphia area if I could possibly avoide it. A northbound overpass has fallen in on the street beneath it. Pennsylvania Governor Josh Shapiro says the southbound lanes are "structurally unsound." This is ordinarily a very heavily traveled section of highway in the mid-Atlantic states. It connects Washingron, DC to New York City. There is a parallel highway on the New Jersey side which goes into Delaware. However, that is a toll road, the New Jersey Turnpike, which is why so many travel on the Pennsylvania side which is free. But now all over the road traffic will be diverted to the Turnpike. At best that will be very slow going. At worst the Turnpike will be a parking lot of several miles.
No doubt Amtrak and the airlines will get as high prices as they can because of the disaster. Still, if I had to travel I would pay what that price. But SEPTA and New Jersey Transit will not raise prices. They coordinate their trains in Trenton so it is possible to travel from Wilmington, DL, change trains in Philadelphia, travel to Trenton, change to a train on the same platform and go on to New York Penn Station. It will not be as fast as Amtrak but it will be a lot cheaper.
I hope the southbound lanes can be opened soon so that instead of a total disaster the highway can become an almost impossible bottle neck.
