Work begins tonight to replace the 20-year-old driving surface on Browns Bridge at the Hall and Forsyth County lines. The material has a lifespan of 10 years.

A single lane will be closed at about 7 p.m. today through 5 a.m. Saturday, according to Katie Strickland, spokeswoman for the Georgia Department of Transportation’s District 1. Those closures will continue every night through the end of the month, Strickland said.

However, the bridge will be completely closed the weekends of Oct. 21-24 and Oct. 28-31 beginning at 9 p.m. that Friday and continuing until 5 a.m. that Monday.

Detour signs will be placed at the intersections of McEver Road/Ga. 53 and Browns Bridge Road/Ga. 369 as well as Keiths Bridge Road/Ga. 306 and Browns Bridge Road/Ga. 369.

Strickland said the project should be completed before the new year, weather permitting.

As of April, Browns Bridge was set to be replaced beginning in 2017. Strickland did not immediately respond to requests for an update on that project.
