SR 114 @ chattooga river tributary, row

This is a $170,000 federal Formula Grant award from the Federal Highway Administration's Highway Planning and Construction Program (CFDA 20.205) to the Georgia Department of Transportation's Division of Intermodal. The grant funding will be used to replace a deficient 1940-constructed bridge culvert on State Route 114 over the Chattooga River Tributary in Georgia. The existing 3-barrel corrugated metal pipe culvert is below current design standards and has significant structural damage, necessitating its replacement to ensure traffic safety. This resilience improvement project will involve the replacement of the aging culvert structure to address the identified transportation infrastructure need.

Project description

Resilience improvement project. Eligible to be fully funded using protect funds. Replacement of a deficient bridge culvert to ensure traffic safety. The structure on SR 114 over chattooga river tributary, structure ID 055-0016-0, the existing bridge culvert was constructed in 1940. IT is a 3-barrel corrugated metal pipe culvert with concrete head walls and dirt aprons. IT is assumed to be an H-15 design, which is below current standards. The concrete headers have large cracks up to 1½" wide and the walls have separated from the steel pipes. The protective coating has worn away from the bottom half of the metal pipes allowing the exposed steel to corrode. Due to the age and condition of these culverts and the design load carrying capacity below current standards, replacement of this structure is necessary.
