Gov. Abigail Spanberger joined state and local leaders to break ground on a $219 million project to widen more than six miles of Interstate 81 in the Harrisonburg area. The project will add a third lane in each direction and replace nine bridges over the interstate, with the goal of improving safety, easing congestion, and supporting economic growth in the Shenandoah Valley.

Why it matters

I-81 is a critical north-south freight corridor that handles 21 million commercial trucks annually, carrying more than $300 billion in goods. Improving the safety and efficiency of this interstate is essential for supporting local economies throughout the Shenandoah Valley region.

The details

The I-81 widening project in Harrisonburg is part of the broader $4 billion I-81 Corridor Improvement Program (CIP), which encompasses 65 capital projects including added travel lanes, interchange upgrades, and truck-climbing lanes. 40 of the CIP projects have already been completed, with 17 currently under construction - the highest level of activity on the interstate since it was built about 60 years ago.

  • Gov. Spanberger broke ground on the $219 million Harrisonburg widening project on April 15, 2026.
  • The Harrisonburg widening project is scheduled for completion in 2032, though motorists should begin using the new travel lanes by late 2031.
  • Widening projects in Bristol and Salem are set to finish by this summer, while the Staunton widening is expected to wrap up next summer.
