The Virginia Department of Transportation has reported the installation of studs on the grid deck of the James River Bridge to improve safety has been completed.

Work was completed three weeks ahead of schedule at about 4 p.m. Friday, VDOT says. A contractor installed 120,000 studs “to provide enhanced vehicle traction on the bridge.”

As a result, all lanes on the bridge have been reopened to traffic. Final work will include “brief bridge lifts” to test counterbalance weights, VDOT says. Lift times will be announced once a schedule is confirmed.

The project was initiated to improve safety after 20 crashes on the bridge between February and early July, believed to largely be a result of the installation of a new deck in December.
