PHILADELPHIA (WPVI) — Several locations around Philadelphia and in Delaware will experience slow traffic Wednesday morning not only because of holiday traffic, but also because of accidents on the roads.

All lanes of I-95 SB approaching RT-141 from Wilmington, Delaware are blocked due to a crash that occurred around 4:15 a.m. I-95 NB near the sandbox on Rt-141 (Exit 5) is also closed due to the crash.

Officials say a dump truck struck the RT-141 bridge in the up position and then struck another truck, sending it flying into bushes on the side of the road.

Helicopter 6 was over the scene where emergency crews could be seen trying to clear the roadway.

DelDOT said I-95 SB at RT-141, RT-141 over I-95 and I-295 at RT-141 are all closed while engineers inspect the bridge for damage.

There is no information on how long the roads are expected to be closed.

Motorists are advised to seek alternative routes.

This accident also causes major delays on I-495 and I-295.
