Cayce, SC 04/03/2023 - The SCDOT will start the southbound portion of the Interstate 77 Bridge Rehabilitation Project on Friday, April 14 at 9 p.m. with the closure of access to I-77 southbound from Bluff Road to I-26.
The northbound portion of the I-77 Bridge Rehabilitation Project began March 24 and is on schedule to be completed by April 2.
SCDOT is rehabilitating a total of 17 bridges on both sides of I-77 between the I-26 interchange (mile marker 0) and Bluff Road (mile marker 5). To minimize traffic disruption, work is being completed under two separate close and detour operations.
Nine northbound bridges and eight southbound bridges are being rehabilitated. Construction activities include the removal of old concrete, pouring new concrete spans, and grinding new concrete to create a smooth driving surface.
SCDOT is repairing and replacing hundreds of deficient bridges across South Carolina as part of the agency's Strategic 10-Year Plan to improve the state's roads and bridges.
