INTERSTATE 81
INTERSTATE 81 LANE WIDENING CONSTRUCTION PROJECT EXIT 137 TO EXIT 141 – The $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 along a five-mile section of both northbound and southbound Interstate 81 in Roanoke County and the city of Salem. Barrier wall is in place along the shoulders. Two lanes of I-81 traffic in each direction are expected to remain open during the project with periodic lane closures scheduled during nighttime hours or outside of peak travel times as needed. Drivers can expect the following lane closures and upcoming traffic impacts in this area on northbound and southbound I-81:
ADDITIONAL TRAFFIC IMPACTS:
- LANE CLOSURES: Alternating left and right lane and shoulder closures during nighttime hours between 8 p.m. and 6 a.m., Sunday through Thursday, are possible. Lane widths will be reduced to 11 feet. Nightly lane closures may be in place along the right lane with possible nightly ramp narrows as needed for guardrail and shoulder strengthening.
LANE CLOSURES scheduled as follows:
Tuesday, January 7 – Northbound left lane closure from mile marker 147.5-148.74.
Wednesday, January 8 – Northbound right lane closure from mile marker 147.5-148.74.
Thursday, January 9 – Northbound right and left lane closures from mile marker 147.5-148.74.
- FLAGGING OPERATIONS: Flagging operations possible on Route 635 and Route 619.
- UNEVEN PAVEMENT: Drivers may experience some uneven pavement and/or rough surface throughout the project.
- TRAFFIC SHIFTS: Drivers may experience periodic lane closures, narrow ramps or quick merges into traffic onto Thompson Memorial Drive from the southbound or northbound exit ramps of exit 140 off of I-81. Work zone located at bottom of the ramp for work on the I-81 bridge at the underpass.
- TRAFFIC SHIFTS ON WILDWOOD ROAD: Expect a work zone with traffic shifts and narrow width on Wildwood Road after exiting I-81 southbound on exit 137 heading towards Salem. Southbound and northbound I-81 exit and entrance ramp narrows are possible at Route 311.
- WORK ZONE SPEED: Drivers should adhere to posted 60 mph speed limits in the work zone and allow space when following a vehicle. Narrow spacing in lanes due to barrier walls, lack of shoulders and lane shifts in various locations, are present.
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. Expected completion in early 2026.
I-81 WIDENING FROM MILE MARKER 143 TO 151 – The I-81 widening project is underway with periodic right and left lane closures in place during nighttime hours 9 p.m. to 6 a.m., on northbound and southbound I-81 for survey and preparation work. Ramps may be narrowed at exit 146 and 143. The expected completion for this project is summer 2031.
I-81 NB & SB DECK OVERLAY AT PEAK CREEK MILE MARKER 95.7 – Repair work is underway on the northbound and southbound bridges on I-81 over Peak Creek near mile marker 95.7. This repair work will require nighttime single lane closures for the duration of the project. Lane closures may occur nightly from Sunday night through Friday mornings between the hours of 8 p.m. and 6 a.m. For the deck overlay process, lane closures may be in place between Sunday nights through Friday mornings. For the southbound lanes these will occur between the hours of 7 p.m. and 10 a.m., and for the northbound lanes between the hours of 6 p.m. through 9 a.m. Details on these closures will be listed below on a weekly basis. Estimated completion is Summer 2025.
- Deck work postponed due to cold weather. This may resume in March.
- Alternating nighttime northbound and southbound left and right lane closures may or may not be in place from mile marker 96 to 94 during the hours of 8 p.m. and 9 a.m. while other work on the project continues.
I-81 NORTHBOUND AT EXIT 105 NEW RIVER BRIDGE REPLACEMENT IN MONTGOMERY COUNTY – Traffic on northbound I-81 has been switched onto the newly constructed bridge over the New River at the Montgomery/Pulaski County line. Lane and shoulder closures may be in place near exit 105. Lane closure may be in effect during the week from 8 p.m. to 7 a.m. Shoulder closures may be in effect at any time during the week. Slow rolls may be performed on I-81 in the north and southbound lanes from mile marker 98 to 109. Speed limit is reduced to 60 miles per hour in the work zone. Shoulder closures will remain in place though the duration of the project. Completion currently expected in fall 2025.
- LANE CLOSURES: Nighttime left lane closures may be in place on I-81 northbound or southbound between mile marker 106 and 104 from 8 p.m. to 6 a.m. the following morning.
- ROUTE 605: Alternating lane closures and flagging operations may be present on Route 605, located under the New River Bridge, for paving operations and work overhead on the bridge.
- SLOW ROLLS: Slow rolls may be utilized periodically on both the northbound and southbound lanes from mile marker 98-109 for structural steel deliveries and setting beams.
CRAIG BOTETOURT SCENIC TRAIL BRUSH CUTTING AND STABILIZATION WORK – Residents along the former Chesapeake and Ohio (C&O) Craig Valley Branch railbed in Botetourt and Craig counties may notice maintenance work continuing on the old railbed. These activities are intended to prevent additional deterioration and to help designers who are developing plans for the Craig Botetourt Scenic Trail. VDOT continues to collect data and conduct site visits and field reviews on the railbed.
