UPDATE: All lanes of I-95 south back open in Stafford

STAFFORD, VA (WWBT) - Traffic is beginning to move once again on Interstate 95 south after a tractor-trailer crash closed all southbound lanes Friday morning.

The lanes reopened around 11 a.m. once crews were able to clear a hazardous material spill caused in the crash around six hours earlier. State Police say a tractor-trailer was rear-ended by another tractor-trailer after it merged from Route 17 to southbound Interstate 95 around 5:12 a.m.

Both two tractor-trailers remained upright and neither driver was injured, however several barrels of phosphoric acid fell off the first tractor-trailer into the right lane of traffic.

The driver of the second tractor-trailer, James E. Harris, Jr., 35, of Chester, Va., was charged with following too closely.
