Single lane closures will continue where Brown Bridge Road (Ga. 369) crosses its namesake bridge on Lake Lanier, as crews pour concrete columns for a new span to replace the existing one.

The closures are scheduled between 9 a.m. and 2:30 p.m. daily through Friday, according to the Georgia Department of Transportation.

“Be advised that this work will be done weather-permitting,” GDOT said. “Please drive alert and slow down when driving through the work zone.”

Browns Bridge carries Ga. 369 over the main channel of the Chattahoochee River in Lake Lanier. A new bridge, with two 12-foot lanes and shoulders eight feet wide, is to be completed next April.
