South Carolina Department of Transportation—I-77 Southbound Deck Replacement over the Catawba River

South Carolina DOT improved safety and the driving experience for motorists with its $13.6 million I-77 Southbound Deck Replacement over the Catawba River project. The 4-lane southbound bridge of I-77 in York County sees more than 50,000 vehicles a day and was rated in poor condition.  The deck required on-going full depth repairs to mitigate the rapid deterioration, exposing SCDOT’s work force to a high-risk environment and causing significant traffic delays due to lane closures. SCDOT decided to fully close the bridge deck for 17 days—an aggressive timeline for all the work to be done, but a small price to pay instead of constant short-term closures it had been experiencing due to the poor state of the bridge deck. SCDOT and completed the new bridge deck and motorists now enjoy a smooth riding surface over the bridge.  Additionally, this project eliminated those frequent traffic delays due to lane closures for deck repairs, giving drivers more consistency and reliability.

Concrete bridge deck pouring continues on the I-77 Catawba River Bridge project site in York County on May 17, 2021. Crews are pouring the final section, measuring 68 feet in length.
