Georgia DOT will begin demolition today on the old State Route 20/Cumming Highway Bridge over the Chattahoochee River in Buford.

The bridge deck, or driving surface, will be removed in 10 feet long sections beginning on the Gwinnett side of the bridge. Work will move towards Forsyth County in 10 feet long sections. The next phase of demolition will remove the horizontal bridge beams and, with the vertical bridge columns to be the last to come down.

This is a systematic demolition to capture and contain all debris out of the River. Demolition is expected to finish by Dec. 31.

The S.R. 20 corridor from Samples Road in Cumming across the Chattahoochee River to Peachtree Industrial Boulevard in Sugar Hill is under construction to be widened to a four lane divided highway in 3 separate projects totaling 7.53 miles. The original bridge over the Chattahoochee River was built in 1947 and does not meet current design standards.
