The Alabama Department of Transportation is planning to close a portion of Highway 77 in Chambers County to replace piping.

According to a news release from ALDOT, starting at 6 p.m., on July 12 through 5 a.m. on July 15, it will perform an emergency culvert pipe replacement on Highway 77 at milepost 7.149.

The following weekend, starting at 6 p.m., on Friday, July 19 through 5 a.m. on Monday, July 22, the same construction will take place on Highway 77 at milepost 7.209.
