Officials said around 10:45 p.m. a truck was traveling on Route 1 near Exit 119 when it rolled down an embankment and then overturned. The truck then began leaking fuel onto Route 13.
Route 1 northbound reopened to traffic around 6:45 a.m. Thursday, but northbound Route 13 remained closed.
The suggested detour is to take Route 9 around the area of the crash.
There is no word on what caused the crash.
No injuries have been reported.
