Virginia Department of Transportation officials said contractors plan to start repairing a bumpy stretch of Interstate 81 on May 15.
Dips in the pavement were caused by concrete underneath being raised up as part of rehabilitation process to stabilize concrete slabs.
VDOT said the slab jacking process involved drilling holes in the ends of the slabs and injecting a chemical grout to stabilize and fill any voids.
Uretek USA is the company that is behind the project; the company has been used to rehabilitate concrete below other stretches of I-81 in Botetourt County.
Adams Construction will oversee the work which is slated to start on May 15.
VDOT said the project will include saw cutting the concrete slabs, removing them and then the stretch will be repaved.
Work will be done between milemarker 147 and 149 between 8 p.m. to 8 a.m.
Drivers are asked to use caution in the area when crews are working on repairs.
