Construction work will begin Monday on a $132 million project to widen I-95 Southbound in the Fredericksburg area.

The Virginia Department of Transportation said it will add three new lanes to the highway.

Initially, drivers will see temporary concrete barriers along the left shoulders of the road. Later in August, VDOT will clear trees from the median.

Drivers should be aware of a work zone stretching from just north of the Exit 133 interchange at Route 17 in Stafford County and ending near Exit 130 interchange at Route 3 in Fredericksburg and Spotsylvania County.

The widening project involves turning the existing I-95 lanes into “collector-distribution” lanes serving local traffic in the Fredericksburg area. In addition, a new bridge over the Rappahannock River will be constructed parallel to the existing bridge.
