The Koehn and Big Pine Shores Roadway and Drainage Improvements project on Big Pine Key is underway. It includes culvert drainage installation, milling, overlaying existing road surfaces with asphalt concrete pavement, regrading roadway shoulders as drainage swales, pavement markings, and signage.
The design included sea-level rise data and County-provided LiDAR elevation data. The project is partially funded by a Florida Department of Transportation Small County Outreach Program Grant and was complete in July 2022.
