New road and bridge projects, including a new bridge on Thompson Bridge Road/Ga. 60 over the Chattahoochee River, took a step toward approval on Wednesday. A technical committee of state, county and city road officials recommended the $12.8 million bridge replacement over the Chattahoochee in North Hall for adoption into the Hall County area’s 25-year regional transportation plan. Only the northbound lane of the bridge would be replaced during construction, which is expected to begin in 2024 using mostly federal transportation cash.
