Cost and schedule ►

Traffic alerts ►

This project will extend the ramp into and the ramp out of the Troutville Rest Area located on southbound Interstate 81 near mile marker 158 in Botetourt County. The off ramp into the rest area will be extended approximately 500 feet and the ramp onto southbound I-81 will be extended approximately 2,100 feet. In addition, the truck parking area at the facility will be expanded by about 10-13 spaces.

VDOT has produced a podcast and a video to provide more information about the Troutville Rest Area ramp extension project. 

Travelers should anticipate the rest area to be closed from late May (after Memorial Day) through early September 2022 (before Labor Day), weather permitting.

While the Troutville Rest Area is closed, southbound I-81 drivers can use the Fairfield Rest Area at mile marker 195 in Rockbridge County or the Radford Rest Area at mile marker 108 in Montgomery County. Portable toilets and parking will be temporarily available for commercial vehicles at the Troutville Weigh Station located on southbound I-81 at mile marker 149.

The Troutville Rest Area ramp extension project is a part of the I-81 Corridor Improvement Program approved by the Commonwealth Transportation Board in December 2018. The more than $2 billion package of focused improvements was funded by the Virginia General Assembly and signed into law in spring 2019.

Additional information about the I-81 Corridor Improvement Program is available at Improve81.org. The website includes interactive maps and schedules and details about upcoming and current projects that are designed to improve safety, increase reliability and foster economic growth along the 325-mile I-81 corridor.


This project will provide safer movements for traffic exiting from or entering into the rest area.  Additional truck parking spaces will be provided.
