Bridge Conditions

In recent safety inspections, Georgia DOT has identified structural deficiencies within the existing bridge on Ponce de Leon over Lullwater Creek. 

Safety Inpections

The Federal–Aid Highway Act of 1970 requires each state to conduct safety inspections for bridges in excess of 20 feet in total length located on public roads. The primary purpose is to verify the safety of the principal components of the bridge: deck, superstructure, and substructure. Standards have also been established for bridge classification.

Bridge Elements

Sufficiency Rating

The sufficiency rating of a bridge is indicative of its capability to remain in service. It compares an existing bridge to a new bridge designed to current engineering standards on a scale of 1 to 100.

Ponce de Leon Bridge over Lullwater Creek Sufficiency Rating: 43.69

With a sufficiency rating of 43.69, GDOT is initiating the concept plan for the bridge's replacement.

Bridge Condition Classifications

Structurally Deficient

Bridges with significant deterioration in load carrying elements. Each element of a bridge is given a rating on a scale of 0 (out of service, beyond corrective action) to 9 (excellent). A condition rating of 4 or less on any of the three elements will result in a designation of structurally deficient.

Functionally Obsolete

Bridges with design issues that no longer meet the criteria for the roadway.
