SH-10 Over Little Green Leaf Creek Bridge Replacement

Project Details

Schemmer provided preliminary and final design services for the replacement of the SH-10 bridge over Little Green Leaf Creek and approximately 0.75 miles of roadway reconstruction. The existing bridge was replaced with a three-span structure with five beams and approximately 250 feet in length. The roadway was constructed on a new causeway on an offset alignment requiring new rock fill to be placed in the lake. Special fill material was investigated for placement by Schemmer's geotechnical partner Terracon. The profile of the roadway and bridge was investigated to potentially raise the profile three to five feet, to allow height for small water craft to pass under the new bridge. Environmental impacts were mitigated by several best management practices including new fish habitat and floating silt curtains, amongst others. Due to the long detour and the high level of tourist travel along the highway, the project was constructed in several phases, under traffic to always allow two-way traffic.
