Start of Dodge County Highway 230 bridge upgrade delayed a week The project was originally supposed to start March 15 but has been pushed back a week to March 22 Author: 13WMAZ Staff Updated: 10:38 AM EDT March 15, 2021 RHINE, Ga. — The start of a significant detour for drivers on Highway 230 has been postponed a week to March 22. Crews will be rebuilding the bridge at 230 and Old Daniels Church Road, just northwest of Rhine. The bridge upgrades will cost around $2.4 million and GDOT says the project will require a 120-day long detour. It was built in the 1960s and doesn’t meet current design standards, but the new construction will make the bridge longer and wider with six-foot shoulders.
