Columbia, S.C. (September 13, 2023) - SCDOT will close the westbound off-ramp from I-20 onto U.S. 1 (Exit 58) overnight on Thursday, Sept. 14. The closure will start at 9 p.m. on Thursday, Sept. 14 and continue through 7 a.m. on Friday, Sept. 15.
The closure will allow for road work that is part of the I-20 Interchange Improvement Project in Lexington County.
Motorists planning to use the I-20 westbound off-ramp to U.S. 1 at Exit 58 should instead follow this detour route: Continue to Exit 55B and change directions at S.C. 6 to enter I-20 eastbound toward Columbia. Continue on I-20 eastbound to U.S. 1 (Exit 58).
Message boards and signs along the route will display detour directions. Motorists are advised to use caution and plan accordingly in case of delays. Motorists may check road conditions at
511sc.org.
With completion expected in spring 2024, the U.S. 1 over I-20 Interchange Improvement Project in Lexington County will fully replace the existing interchange to improve overall traffic through the area.
