County and Local Drawbridge Systems

Status: Existing

Description: Includes Bridge of Lions on SR A1A over Matanzas River in St. Augustine, Crescent Beach Bridge on SR 206 over Matanzas River in Crescent Beach, and St. Mary's River Bridge on US 17 over St. Mary's River in Nassau County. Miami–based US Coast Guard determines schedule for bridge openings and closings based on marine traffic and weather conditions. Marine traffic receives information from the Coast Guard on bridge schedules. Bridge tenders working for FDOT actually control the raising and lowering of the bridges. Transponders that provide bridge status information (none currently implemented) would provide this information directly to the county and local operating agencies.
