I-77 Widening and Rehabilitation Project in Richland County

The South Carolina Department of Transportation (SCDOT) announces the start of construction on the Interstate 77 Widening and Rehabilitation Project in Richland County. The project begins on I-77 between the I-20 and Percival Road interchanges and extends to Blythewood Road.  The purpose of this project is to improve safety, rehabilitate the aging interstate, bridges, and reduce traffic congestion.

The $88 million design-build contract was awarded to Archer Western, A Member of the Walsh Group, who has proposed an aggressive work schedule. Construction will begin on June 20, 2016, and is estimated to be substantially complete in July 2018.

During construction, Northbound and Southbound I-77 will be widened to add an additional travel lane in each direction beginning between SC 12 (Percival Road) and ending at the Killian Road Interchange.  The additional lanes will be constructed within the existing interstate median.

All of the I-77 bridges within this area will also be widened toward the median to support the new lanes, including I-77 northbound/southbound bridges over I-20 mainline, I-77 northbound/southbound bridges over I-20 westbound ramp to I-77 southbound, I-77 northbound/southbound bridges over Windsor Lake Boulevard, I-77 northbound/ southbound bridges over Windsor Lake and Jackson Creek, and I-77 northbound/southbound bridges over Edgewater Drive and Little Jackson Creek. 

Traffic will be staged in this area during construction, utilizing temporary concrete barriers to separate the work zone from interstate traffic. All I-77 travel lanes will remain open during daytime hours to minimize impacts to motorists.  Any lane closures needed for construction will be performed at night, when the volume of traffic is reduced.

The project also includes the rehabilitation of the existing I-77 Southbound pavement from just north of Killian Road to Blythewood Road.  This work is scheduled to begin June 20, 2016, and will consist of repairing and then overlaying the concrete pavement with a new asphalt pavement. The majority of work in this area will be performed under nightly lane closures to minimize traffic impacts. Drivers traveling through the construction zone are asked to be aware of equipment and crews working adjacent to traffic at all times.
