Traffic is backed up on I-95's northbound lanes between exits 38 and 39 after crash involving a tractor-trailer and a pickup truck Thursday morning.
The right lane on the northbound side is closed.
State police say the driver of the pickup truck was taken to the hospital for evaluation.
Some cars on I-95 are taking Exit 34, so Route 1 may be busier than normal.
Emergency crews were on the scene to clear the accident.
