Road Notice: Interstate 81 Lane Widening Construction from Exit 137 to 141

VDOT traffic alert

A $179 million design-build project to widen both directions of I-81 between mile markers 136.6 and 141.8 from two to three lanes is underway. Work is being performed on the inside and outside shoulders along a five mile section of both northbound and southbound Interstate 81 in Roanoke County and the City of Salem. Barrier wall will be installed along the shoulders in the spring and summer. Two lanes of I-81 traffic in each direction will remain open during the project with periodic lane closures scheduled during nighttime hours or outside of peak travel times as needed. The project also includes replacing six bridges, widening two bridges, installing approximately 2.6 miles of sound barrier walls along northbound I-81, improving the southbound exit 137 off-ramp intersection at Wildwood Road and adding interchange lighting at exits 137, 140 and 141 are also included in the project. Expected completion in early 2026
