To update, the speed limit on the Gasparilla Island Bridge Authority swing bridge and its two fixed bridges has been lowered to 10 mph. Speed bumps have been installed on the aprons of all three bridges. Supposedly rated at 10 mph, the speed bumps tend to bring traffic to a halt rather than cause it to slow down. As you turn onto the Boca Grande Causeway, look for Charlotte County Sheriff's Office cars in the boat ramp parking lots to your right as you approach the toll plaza. Police also tend to park near the southern apron of the swing bridge, on the north and south aprons of the twin fixed bridges and on the curve in the area of Marina Village to the south of the southernmost fixed bridge. The causeway speed limit is 35 mph. NOTE: The 35 mph speed limit has not been approved by the Florida Department of Transportation as required by state statute. The bridge authority has taken a legal position that approval is not required. FDOT says it is. This is not an issue to argue with the officer at the time you are stopped, however, as the average CCSO deputy would have trouble spelling FDOT let alone understand its regulatory authority. Additionally, a fairly recent traffic study conducted by CCSO showed the speed driven by 87 percent of the vehicles clocked on the causeway was 47 mph. This means the speed limit, if challenged in court, should legally be no lower than 45 mph under FDOT regulations.
