Update, 10:57 a.m.: Police have charged the driver of one of the tractor-trailers involved in this morning’s crash on I-95 South in Stafford County.

James E. Harris, 35, of Chester, Va., was charged with following too closely, police said. Harris is accused of rear-ending another tractor-trailer, driven by 40-year-old Phillip C. Harris of Hopewell, Va., early Friday morning. The two men are not related, police said.

Neither of the drivers was injured, but the crash did close the southbound lanes of I-95 at Exit 133 for several hours. Police said the lanes could reopen as early as 11 a.m.

Update, 9:19 a.m.: Virginia State Police are investigating the tractor-trailer crash that closed a portion of Interstate 95 in Virginia for several hours Friday morning.

Police said the incident involved two tractor-trailers that collided shortly after 5 a.m. in the southbound lanes of I-95, just south of Exit 133/Falmouth in Stafford County. The two vehicles came to a stop on the right shoulder of I-95 South. Police said that despite earlier reports of an overturned tractor-trailer, both vehicles remained upright and neither driver was injured.

However, the impact of the crash did cause one of the tractor-trailers to lose part of its load, tossing several barrels of an organic, corrosive liquid onto the right southbound lane. There was a minor leakage from at least one of the damaged barrels, police said. HazMat crews from Stafford and Fredericksburg have been working to contain and clear the spill.

The crash remains under investigation and the southbound lanes of I-95 remain closed. They are expected to reopen around noon, police said.

Update, 8:54 a.m.: VDOT officials say the southbound lanes of I-95 in Stafford County will be closed until at least 11 a.m.

Traffic is being detoured at Exit 133 to southbound Route 17 and then onto Route 1. Vehicles can return to I-95 South at Exit 130/Route 3 or Exit 126/Spotsylvania. Drivers who are not already on I-95 South should avoid the interstate before Exit 133 completely and head straight toward Route 1.

VDOT warns that there is heavy congestion on Route 17 and Route 1 due to the additional traffic.

Update, 8:29 a.m.: Lane closures on Interstate 95 in Virginia are expected to last through much of Friday as crews work to clear an overturned tractor-trailer carrying hazardous materials, authorities said.

The tractor-trailer overturned early Friday morning on the ramp from Route 17 to I-95 South, near mile marker 133.

There are significant back-ups because of the volume of cars heading south on the interstate. Drivers already on I-95 continue to be diverted off the roadway to Route 17.

Virginia Department of Transportation officials are urging drivers to avoid I-95 South. Officials don’t have an estimated time for the lanes to reopen.

Original post, 6:31 a.m.: The southbound lanes of Interstate 95 are closed in Stafford after a tractor-trailer overturned on the ramp from Route 17 to I-95.

All lanes are closed due to the crash investigation and clean-up. It was not immediately known what the tractor-trailer was transporting.

Traffic on I-95 South is being diverted to Route 17. Drivers can expect delays and are urged to avoid the area.
