A jackknifed tractor-trailer slowed Friday morning traffic to a near standstill for hours along Interstate 95.
The big rig, with United States Postal Service emblems on the side, crashed in the northbound lanes just before the Academy Road Exit in Northeast Philadelphia around 5:45 a.m. causing a fuel spill.
Only the left shoulder could get past the scene northbound as average speeds lowered into the single-digits and travel times from the Vine Street Expressway (I-676) to Woodhaven Road (Route 63) ballooned to more than 100 minutes at one point -- it's normally a 13-minute drive.
No word yet on possible injuries.
NBC10 First Alert Traffic reporter Jessica Boyington said drivers could use Frankford Avenue as an alternate route but should expect delays.
Crews cleared the crash and lanes began moving again around 9:30 a.m. but some residual delays remained.
