The Phase 2 Total Project Length Roadway and Bridge is 3.3 Miles consisting of a 2-lane roadway.

Bridge Information
The total bridge length is 2.3 miles.  The western bridge approach of bridge 1 is located east of the Osceola Camp and the eastern bridge approach of bridge 2 is located west of the Airboat Association/Frog City. The bridges will create conveyance openings by removing sections of the existing highway corresponding to the locations of the new bridge spans. The bridges were constructed on a centerline approximately 50 feet south of the centerline of the existing roadway in order to maintain motor vehicle traffic during bridge construction. The project also includes the construction of the approaching roadways, drainage and retention systems, utility coordination and canal excavation.
