*Media availability March 21, 2023 – Details to follow*
Columbia, S.C. (March 10, 2023) – SCDOT will start the Interstate 77 Bridge Deck Rehabilitation Project on Friday, March 24. Weather permitting, the project will begin March 24 at 9 p.m. with the closure of access to I-77 northbound from I-26 to Bluff Road.
The project will rehabilitate a total of 17 bridge decks on both sides of I-77 between the I-26 interchange (mile marker 0) to Bluff Road (mile marker 5).
To minimize traffic disruption, work will be completed under two separate close and detour operations. The northbound closure will begin March 24, and the southbound closure will take place in late April 2023.
Nine northbound bridges and eight southbound bridges will be rehabilitated. Having assessed the condition of all 17 bridge decks, SCDOT will rehabilitate each bridge deck as needed. Some of the construction activity will 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.
