I-95 SOUTHBOUND REPAIR WORK CONTINUES
Right lane will be closed Monday-Thursday during daytime hours at mile marker 147 in Stafford County
FREDERICKSBURG – Work to stabilize an embankment along Interstate 95 southbound in Stafford County will continue for several weeks to halt erosion near the travel lanes.
The right lane of I-95 southbound will be closed at mile marker 147 from 8 a.m. to 2:30 p.m. Monday-Thursday, just south of Exit 148/Quantico Marine Corps Base. Lane closures will be lifted whenever congestion surpasses 3 miles. No lane closures will occur Friday-Sunday.
“Closing a travel lane of Interstate 95 is always our last resort,” said Marcie Parker, P.E., VDOT Assistant District Administrator for Maintenance and Operations. “However, without immediate action, this erosion was likely to spread beyond the shoulder, which would lead to even greater disruption for motorists. Completing this work now will allow us to finish it ahead of the spring and summer travel season, and protect the public infrastructure.”
Repairs are estimated to take a minimum of four additional weeks.
To restore the shoulder and protect the travel lanes, the Virginia Department of Transportation (VDOT) has hauled away 2,494 tons of unsuitable soil from the slope.
VDOT and its contractors have replaced the unsuitable soil with stone and built a 12-foot retaining wall to stabilize the area.
Specialized equipment, a soil nail launcher, was hired to work on the steep terrain. The soil nail launcher creates a retaining wall by drilling holes beneath the roadway, and inserting steel rods into the ground. The rods are covered with a mesh wire net and anchored with bolts. The entire surface is then covered with shotcrete, a concrete material.
After an assessment by VDOT geotechnical staff this week, it was determined that an additional 12 feet must be added to the retaining wall, doubling its size. Also, larger stone will be used to support the slope in the retaining wall.
Work must be performed during daytime hours, when temperatures are warm enough for the concrete substance to properly set, holding the retaining wall in place.
