I-81 Improvements Continue Across Virginia as Safety, Widening and Traffic Projects Expand

Major construction and safety improvements continue along Interstate 81 across Virginia, with projects underway from Bristol to Winchester as state transportation officials work to reduce congestion, improve safety, and prepare the corridor for future growth.

The Virginia Department of Transportation says the I-81 Corridor Improvement Program has now become one of the largest transportation initiatives in the Commonwealth, with widening projects, bridge replacements, truck-climbing lanes, interchange redesigns, and safety operations taking place simultaneously across multiple regions.

TRIP Program Marks Five Years on I-81

One of the most successful operational improvements has been the expansion of VDOT’s Towing and Recovery Incentive Program, known as TRIP, which was extended to Interstate 81 five years ago.

The program partners with heavy-duty towing and recovery companies positioned throughout the 325-mile I-81 corridor. Under the agreement, specialized tow providers respond quickly to major crashes involving commercial vehicles blocking travel lanes.

According to VDOT, TRIP providers have:
• Responded to more than 2,000 incidents.
• Earned incentive payments 97 percent of the time.
• Reduced average scene clearance times to 77 minutes.
• Improved incident response times to an average of 34 minutes.

Officials say the faster response times have dramatically reduced traffic backups and the risk of secondary crashes.

“With the addition of TRIP, we can open blocked travel lanes more efficiently and much quicker,” said Brian Holt, Bristol District Traffic Operations Engineer. “Having a tow company on-call 24/7 that responds with the appropriately trained staff and the specialized equipment needed to clean up a tractor-trailer crash saves several miles of queue and hours of congestion.”

Bristol Widening Project Complete

Drivers in Southwest Virginia are already seeing the results of one major improvement project.

VDOT announced the completion of a three-lane widening project on southbound I-81 between exits 10 and 7 in Bristol. The $38 million project widened bridges, added concrete barriers, installed noise walls, and improved traffic flow along one of the region’s busiest stretches of interstate.

Construction began in January 2024 and was substantially completed by the end of 2025, with final paving work wrapping up in spring 2026.

“Completing the widening of southbound I-81 in Bristol marks another important step in delivering safer, more reliable travel for the residents, businesses, and visitors who depend on this corridor every day,” said Bristol District Engineer Tabitha Crowder.

Roanoke and Salem Widening Approved

The Commonwealth Transportation Board has also approved a $237.75 million contract to widen both directions of I-81 in Roanoke County and Salem between mile markers 133.8 and 137.

The project is part of a larger nine-mile widening initiative stretching from Montgomery County into the Roanoke region. Construction is expected to begin in spring 2027 after design work is completed.

The widening project will:
• Expand portions of I-81 from two lanes to three lanes.
• Replace bridges.
• Improve interchange ramps.
• Install concrete barriers.
• Add noise walls in some areas.

The full project is expected to continue through 2035.

Winchester Area Projects Bring Major Changes

In Northern Virginia, more than $250 million in planned upgrades are coming to Interstate 81 near Winchester and Frederick County.

VDOT recently held a public hearing attended by approximately 60 residents, business owners, and stakeholders to discuss plans for:
• Widening I-81 between mile markers 317 and 319.
• Rebuilding Exit 317 into a diverging diamond interchange.
• Realigning the northbound off-ramp.
• Constructing a new park-and-ride lot.
• Reconfiguring nearby roadways.

The Winchester North projects are funded through both the I-81 Corridor Improvement Program and Virginia’s SMART SCALE transportation funding system. Design-build bids are expected in late 2026, with construction potentially beginning a year later.

Shenandoah Valley Projects Continue

Multiple projects are also underway throughout the Shenandoah Valley, including in Frederick, Warren, Shenandoah, Rockingham, Augusta, and Rockbridge counties.

Among the largest:
• A four-mile widening project near Staunton is now more than 60 percent complete.
• Truck-climbing lanes are being added near Weyers Cave.
• A four-mile southbound widening project continues near Strasburg.
• A nearly seven-mile widening project has started near Harrisonburg.

The Strasburg project includes widening over the CSX railway and a new bridge over Cedar Creek. Traffic shifts are expected later this summer as construction moves into the next phase. Final completion is anticipated in fall 2028.

Near Harrisonburg, a $219 million project includes nine new bridges and shoulder widening work, with completion expected in 2032.

Focus on Work Zone Safety

As construction activity increases, VDOT says work zone safety has become a growing concern.

According to the agency, crash data from 2025 revealed a sharp increase in rear-end crashes, speeding and aggressive driving behavior within I-81 work zones. In the Staunton District alone, 61 percent of work zone crashes were rear-end collisions tied to following too closely.

VDOT has increased digital safety messaging throughout the corridor with reminders such as:
• “Drive With Focus”
• “Increase Follow Distance”
• “Speeding Fines Higher”

Officials say the combination of widening projects and traffic growth means drivers will continue encountering construction zones for years to come.

“As we continue work across the I-81 corridor, safety remains our shared responsibility,” VDOT said in the report. “Every driver plays a role in preventing crashes by slowing down, staying alert, and giving others space to move through work zones safely.”
