The Virginia Department of Transportation anticipates the project to be completed by November 2018.
The bridges, one constructed in the 1940s and one in the 1960s when the route was widened to four lanes, have reached their life span and are ready for replacement.
The bridges carry approximately 24,000 vehicles per day.
During construction, there will be one 12-foot-wide travel lane in each direction. For the first phase of construction, north and southbound traffic will use the northbound bridge while the southbound bridge is reconstructed.
Access to businesses, entrances and connecting roads within the project limits will be maintained during construction.
The speed limit inside the work zone will be lowered to 35 mph to enhance safety for motorists and highway workers. For more details regarding the project, visit VDOT’s Projects and Studies website.
According to the Virginia Department of Transportation, Vecellio & Grogan Inc., of Beckley, W.Va., will be responsible for the bridge-replacement project.
VDOT’s Bristol District consists of 12 counties in Southwest Virginia: Washington, Smyth, Lee, Scott, Russell, Buchanan, Tazewell, Bland, Wise, Dickenson, Grayson and Wythe.
