Under Construction: Interstate 81 Widening Exit 141 to 143 - Roanoke County
Cost and schedule ►
Traffic alerts ►
One new lane in each direction of I-81 and two lanes northbound onto I-581 at exit 143 opened just before Thanksgiving between mile markers 141 and 143.
All lanes will remain open through winter with periodic lane closures at night as needed. The final surface paving and markings for northbound will resume with the next paving season in spring 2022.
Left and right lane closures may be in place on I-81 northbound or southbound during nighttime hours from 8 p.m. to 6 a.m. once paving resumes in spring 2022.
Speed limit will remain 60 mph in the work zone.
Public outreach ►
A design public hearing was held for this project on November 14, 2017 at Northside High School in Roanoke.
This $38-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 an additional lane in both directions will alleviate congestion and provide for safer traffic movements at these exits.
The new northbound lane will begin near exit 141 on-ramp and continue with the I-81 northbound right lane transitioning to become the exit 143 off-ramp on to I-581.
The new southbound lane will extend the exit 143 on ramp and terminate near exit 141.
As part of the project, sound walls will be constructed along two sections of northbound I-81.
Approximately 70,000 vehicles use this section of I-81 each day, making it the most heavily travelled portion of I-81 in Virginia.
This purpose of this project is to alleviate congestion and provide for safer northbound and southbound merge movements between exits 141 and 143.
