Specifications include, but are not limited to: This project includes the replacement of the existing culvert and pedestrian bridge at Alligator Lake on CR30A between CR83 and CR283. The existing culvert and bridge shall be demolished and removed during clearing and grubbing. A new, precast concrete bridge and supporting components will be installed, the roadway and multiuse path realigned, and new drainage facilities constructed. Precast concrete bridge components and concrete pilings will be provided by Walton County at the Walton County Maintenance Yard located at 1002 Co Hwy 83, Santa Rosa Beach, FL, approximately two miles from the project site. The contractor will be responsible for retrieving these components from stockpile, delivery to site, and installation. The construction area will require complete closure of the road and a detour installed. The contractor will be responsible for providing detour signage and advanced message boards throughout the duration of the construction. Extreme caution is required in the construction area to avoid impacts to existing underground utilities and drainage structures to remain.
