Eastbound lanes are closed at 5 p.m. Wednesday west of Route 28 after a vehicle struck an I-66 gantry.

Part of Interstate 66 has reopened in the Centreville area Wednesday evening after a vehicle hit an overhead gantry, closing the eastbound lanes for more than four hours, officials said.

About 4:45 p.m., the Virginia Department of Transportation tweeted that I-66 eastbound was closed after a vehicle struck the gantry, which then was found to be structurally unsound.

VDOT spokeswoman Ellen Kamilakis said the sign was part of a traffic management system that was disabled for the expansion of I-66.

There were no reported injuries in the crash, she said. Eastbound traffic was diverted to Route 29, and ramps from Route 29 and Route 28 to I-66 were shut down as crews worked to remove the gantry.

“We can’t have anyone driving underneath,” she said. “They have crews en route coming to take the entire structure down.”

The overhead structure was removed about 8:20 p.m., VDOT said. The eastbound lanes reopened more than a half-hour later.

In a separate incident, Virginia State Police arrested Jordan L. Golladay, 25, of Manassas, on charges of driving under the influence and driving on a suspended license, Corinne Geller, a spokeswoman for the agency, said late Wednesday.

State police received calls about a Toyota Corolla that witnesses told police was driving recklessly in the westbound lanes of I-66 in Fairfax County about 1:45 p.m., Geller said in a statement.

A responding trooper pulled behind the Toyota and activated his patrol vehicle’s lights and sirens to initiate a traffic stop, but the vehicle fled west, police said. Heavy traffic eventually forced the Toyota to stop.

At that time, Geller said the trooper saw a Kia run off the side of I-66 and continue into the median, where it hit the pole supporting the highway sign. Police said the crash caused the Kia to catch fire.

The trooper got out of his cruiser, directed the Toyota’s driver to pull over to the shoulder and park, then ran to the aid of the driver in the Kia, Geller said.

Police arrested Golladay, who was taken to the Fairfax County jail.

The driver of the Kia, Andrea Nunez, 27, of Manassas, Va., was treated at the scene for minor injuries.

The incident remains under investigation, police said.
