Under Construction: Warren County – Interstate 81 Exit 300 Southbound Acceleration Ramp Extension and Bridge Widening over Route 840 (Water Plant Road)
Cost and schedule ►
Traffic alerts ►
Be alert for overnight left-lane closures on northbound and southbound between mile markers 299 and 301 as contractors move equipment and materials in and out of the work zone. Lane closures are possible from 8 p.m to 7 a.m. through lane January 2023.
The work zone speed limit on southbound I-81 is 55 miles an hour for the remainder of the project.
The junction of I-81 and I-66 is a congested area, and motorists should use extra caution when traveling through the work zone. Backups on southbound I-81 and westbound I-66 are possible due to high traffic volumes, daytime shoulder closures and overnight lane closures. Drivers should also be alert for traffic-lane shifts on southbound I-81
Drivers using Route 840 can expect flagger traffic control during daytime or overnight hours, and short-term roadway closures when crews install beams for the new I-81 overpass bridge.
Throughout this project, updated traffic alerts can be found here and on the Staunton District Travel Center page.
Real-time traffic information is available on the VDOT 511Virginia.org website and also by calling 511 on your landline or wireless phone. The VDOT Staunton District Twitter feed is at @VaDOTStaunton.

This project extends the Interstate 81 southbound exit 300 acceleration lane from the Interstate 66 westbound ramp. The purpose of this project is to to safely accommodate merging traffic and growing truck volumes on Interstate 81 at the south end of the exit 300 interchange.
The project extends the existing southbound 1,400-foot acceleration lane and 250-foot taper to a 2,030-foot acceleration lane with a 300-foot taper. The 128-foot long southbound bridge over Route 840 (Water Plant Road) will be widened from 42 feet to 54 feet to accommodate the extended lane. A small drainage structures may need to be extended.
During construction temporary closures will occur on Route 840 to place beams for the I-81 bridge over Route 840. In 2020 the daily average traffic count was estimated at 557 vehicles per day. For the design year of 2042 the estimated average daily traffic volume is 672 vehicles per day.
All interstate work will be performed in the median and the project will not have any right-of-way impacts.
The purpose of this project is to improve mainline operations and improve safety at the high-speed merge of traffic onto southbound I-81 from I-66 westbound.
