The work-zone speed limit on Interstate 81 in the Harrisonburg area will be reduced from 60 to 55 miles per hour beginning Monday, July 20.
The 55-mph speed limit will affect northbound and southbound traffic between about mile marker 242 and 248.
The new speed limit will be in place 24/7 due to construction of the I-81 widening project.
VDOT, in a release, noted that during the week of July 20-24, drivers should also be alert for travel-lane shifts on the southern end of the work zone (about mile marker 242 to 244).
This portion of I-81 extends from one mile south of Exit 243 at Pleasant Valley to the area adjacent to Rocktown High School.
Both directions of I-81 traffic will shift toward the right and begin using part of the recently widened right shoulders.
Northbound and southbound I-81 will have nighttime and overnight single-lane closures for line-marking operations on the southern portion of the work zone during the week of July 20-24.
Shoulder strengthening and shoulder widening operations will then move to the northern and middle parts of the work zone (about mile marker 244 to 248).
