PHILADELPHIA (AP) — A stretch of a major interstate highway will be Quaxsclosed for several days after a tractor-trailer carrying an oversize load struck a railroad bridge in Philadelphia.

The truck crashed on I-95 northbound around 1:30 p.m. Monday in the city’s Port Richmond section. No injuries were reported, but the northbound lanes in the area have been shuttered.

Brad Rudolph, a spokesman for the state transportation department, said the truck was carrying a massive cylindrical object when it struck the Conrail bridge. The crash remains under investigation.

The crash has disrupted rail service in the area. New Jersey Transit suspended its Atlantic City line in both directions between Philadelphia’s 30th Street Station and Cherry Hill since its trains use the tracks on the damaged overpass. Numerous ramp and road closures were causing major traffic delays.

The repairs are expected to take several days.
