St. Johns River Crossing NEPA Analysis

The Florida Department of Transportation’s (FDOT) First Coast Expressway project aims to provide a multi-lane limited access toll facility to connect Interstate 95 (I-95) in St. Johns County and Interstate 10 (I-10) in Duval County. This project has proposed 46.5 miles of roadway, including a new bridge over the St. Johns River. In the 2013 Final Environmental Impact Statement (FEIS) for the St. Johns River Crossing, FDOT and the Federal Highway Administration (FHWA) analyzed the proposed bridge for climate change impacts related to sea level rise and storm surge. They evaluated projected sea level and storm surge elevations against the vertical clearance and approach elevations for each proposed alternative. The analysis found that storm surge impacts could increase slightly due to continued sea level rise. However, the projected increases in sea level and associated storm surge through 2100 are not expected to render any of the proposed bridge Build Alternatives dysfunctional.
