Maybe you’ve noticed trees being cleared near a bridge over Little River, a body of water that makes up part of the Cherokee and Fulton county line.

Well, here’s the reason: the Georgia Department of Transportation is clearing the site in order to replace the bridge on Arnold Mill Road, which is also Ga. 140.

The two-lane bridge, built in 1952, is being replaced due to its structural integrity. The bridge’s surface has been repaired numerous times, there is some corrosion and deterioration, and it was designed using a truck configuration that weighs less than the current state legal truck weights, according to GDOT.

The site needs to be cleared by the end of the month because of a seasonal environmental prohibition; bats live under the existing bridge and cannot be disturbed between March 31 and June 30, a GDOT spokeswoman said.

Construction will take two years and the completion date is anticipated for December 2018.

After the new two-lane bridge is constructed, the existing one will be torn down.
