About
The Florida Department of Transportation (FDOT) is conducting a Project Development and Environment (PD&E) Study for the Card Sound Road Bridge located on County Road (CR) 905A/Card Sound Road, connecting Monroe County to Miami-Dade County between Florida City and North Key Largo.
This project involves evaluating the potential replacement of Card Sound Bridge (Bridge Identification Number 904990), a high-level fixed bridge crossing over the Atlantic Intracoastal Waterway (ICW). CR 905A serves as an alternate principal route into and out of the Florida Keys from the mainland and serves as an emergency evacuation route.
The project limits extend from south of Milepost 5 to Milepost 6.242 (Miami-Dade/Monroe County Line), for a total distance of 1.242 miles (including the bridge).

The purpose of this project is to evaluate alternatives that will address the structural degradation and substandard design elements of the existing Card Sound Bridge. The alternatives will also evaluate improving emergency evacuation/response times and providing enhanced or new bicycle and pedestrian facilities

A PD&E Study is FDOT’s process to evaluate the social, cultural, natural, and physical resource impacts associated with a planned transportation improvement project. Community engagement is a core component of the study. There will be many opportunities for the community to learn about the project and share feedback to inform the Study. See below for upcoming public meetings.
Note: Schedule is subject to change.

The environmental review, consultation, and other actions required by applicable federal environmental laws for this project are being, or have been, carried-out by FDOT pursuant to 23 U.S.C. § 327 and a Memorandum of Understanding dated May 26, 2022, and executed by the Florida Highway Administration (FHWA) and FDOT.
Public participation is solicited without regard to race, color, national origin, age, sex, religion, disability, or family status.
