Replacement of Bridges Nearly Completed on I-77 in Chester County, Traffic to Shift back to Mainline on Wednesday, June 30, Weather Permitting

The South Carolina Department of Transportation (SCDOT) reports that work to replace two bridges over Interstate 77 in Chester County has progressed to the point where traffic will be shifted back to the mainline of the highway by Wednesday morning, June 30, weather permitting.

Earlier this month, traffic was shifted from the two lanes of northbound and southbound I-77 onto the exit ramps, crossing S-12-56 (Old Richburg Road) uninterrupted, and then resuming travel on I-77.  

Both bridges are being replaced following the discovery of cracks in some of the steel beams on these two bridges during a routine inspection on April 29.

Following an order by Transportation Secretary H.B. Limehouse Jr. to issue an emergency contract, work began on June 7 to replace the 12 steel girders in both bridges.

Final touches on the bridge work will be done leading up to Tuesday evening, when crews will begin to re-establish the traffic pattern back on the interstate mainline. This will require the left lane of I-77 in both directions to be closed beginning at 7 p.m. Tuesday.

The mainline traffic shift will be re-established by Wednesday morning, weather permitting.

Ramps and S-12-56 will remain closed for approximately 3-4 weeks as crews complete the project.

Secretary Limehouse praised the work of the SCDOT staff and its partner, United Contractors. 

“Any project that involves the safety of the public is important no matter how large or small. Replacing two bridges on an interstate highway with high traffic volumes is both a major safety priority, and needs to be completed as quickly as possible to keep traffic moving. That’s what’s taking place on I-77 in Chester County,” said Limehouse.
