In Design: Interstate 81 Widening Exit 137 to 141 - Roanoke County and City of Salem

Cost and schedule ►

Public outreach ►

The purpose of this project is to provide additional capacity and improve safety by adding an additional lane in both directions of Interstate 81 between mile markers 136.6 and 141.8. 

This segment of I-81 experiences frequent congestion and major delays related to significant crashes and incidents as identified in the I-81 Corridor Improvement Plan completed in December 2018. Along this section of I-81 between October 2016 and September 2019, there were 312 crashes. Traffic volumes vary between interchanges and range between 63,000 and 67,000 vehicles per day with 21-22 percent heavy trucks.

The proposed improvements are intended to increase capacity, lower crash rates, lessen delays and enhance crash response times.  These include:

  • Adding one additional lane in each direction of I-81
  • Replacing the pairs of bridges over Route 112 (Wildwood Road), Route 635 (Goodwin Avenue) and Route 619 (Wildwood Road)
  • Widening the pair of bridges over Route 311 (Thompson Memorial Drive) at exit 140
  • Improving the intersection of the southbound exit 137 off ramp and Wildwood Road
  • Adding interchange lighting at exits 137, 140 and 141
  • Improving acceleration and deceleration lanes where needed
  • Installing concrete barrier wall along narrow median sections
  • Constructing approximately 2.6 miles of sound barrier walls along the northbound lanes
