A tractor-trailer hit the center wall on Interstate 95 northbound near the Lantana Road exit Tuesday morning, sending concrete into the southbound lanes.
All southbound lanes are back open after earlier closures.
The crash occurred at about 6:10 a.m. and caused delays much of the morning.
Chopper 5 flew over the area at 6:30 a.m. and spotted the semi stopped at the scene with traffic delays already occurring.
The cause of the wreck has not been released.
The semi was a Yuengling truck, but it's unclear if it was hauling any beer.
No injuries have been reported.
