Project Details

This $62-million project will add an additional lane along northbound and southbound I-81 between exit 141 (Salem) and exit 143 (Roanoke) in Roanoke County.

Adding a two-mile auxiliary lane in both directions will alleviate congestion and provide for safer traffic movements at these exits.

The primary purpose of this project is to alleviate congestion and provide for safer northbound and southbound merge movements between exits 141 and 143.

As part of the project, sound walls will be considered along northbound I-81.

The northbound auxiliary lane will connect the exit 141 on-ramp directly to the exit 143 off-ramp and will be constructed along, and adjacent to, the existing outside through lane.

The southbound auxiliary lane will extend the exit 143 on ramp and become the new inside through lane. The existing outside through lane will become an exit only lane that will end at the exit 141 off-ramp.

As of 2016, between 63,000 and 70,000 vehicles travel this section of I-81 each day, making it the most heavily travelled portion of I-81 in Virginia.
