FDOT SR 15 at SR 16 intersection and access improvements

Project Summary

Hanson provided final design for improvements to safety, traffic flow and access to a gas station at the intersection of state roads 15 and 16 in Green Cove Springs, Florida. The upgrades involved dual southbound left-turn lanes on State Road 15, widening SR 16 to four lanes, installing traffic separators, updating yellow and red clearance intervals, rebuilding traffic signal assemblies and upgrading pedestrian features.

Hanson’s drainage engineering services involved ditch reconstruction, minor storm collection system design, cross drain extensions and permitting. Proposed design included implementation of Biosorption Activated Media strips adjacent to the state road 16 shoulders, which provided stormwater treatment through nutrient removal.

The team also provided public involvement to support the project design and created several exhibits for public meetings.
