Construction crews are boring beneath U.S. 221 in Roanoke County to make a tunnel through which the Mountain Valley Pipeline will pass.
The project atop Bent Mountain is one of 59 highway crossings the natural gas pipeline will make on its way through the counties of Giles, Craig, Montgomery, Roanoke and Franklin.
Most of the crossings will involve boring under the highways with little disruption to traffic, according to Jason Bond, a spokesman for the Virginia Department of Transportation.
