The intent of the roadway speed study, performed by Johnson Engineering with support from city staff, is to analyze existing conditions (city-wide speed limit signage and passing zones along Sanibel Captiva Road) and, as necessary, traffic data to determine appropriate posted speed limits within select locations in the City of Sanibel. City-wide speed limit signage and passing zones along Sanibel-Captiva Road are also addressed.
This is a city-funded project; no grant funds are being used.
Specific tasks include data collection and analysis over a seven-day, 24-hour traffic period at six locations within the city, spanning 20 consecutive days from November 19, 2025, to December 9, 2025. Those locations include four on Sanibel-Captiva Road, one on Periwinkle Way east of the Periwinkle Way bridge, and one on Rabbit Road.
Here are some highlights from the preliminary draft report showing just some of the data collected:
Sanibel Captiva Road, east of Pine Avenue, 37,908 cars driving 30-35 mph, 5,842 cars driving 40-45 mph, 21 cars driving over 60 mph.
Sanibel Captiva Road, west of Buckthorn Lane, 43,036 cars driving 40-45 mph, 10,604 cars driving 45-50 mph, 1,924 cars driving over 55 mph, with 20 of those driving over 70 mph.
Sanibel Captiva Road, east of Gulf Pines, 61,519 cars driving 35-40 mph, 10,037 cars driving 45-50 mph, 39 cars driving over 70 mph.

Rabbit Road, 5,248 cars driving 35-40 mph, 1,746 cars driving 35-40 mph, 18 cars driving over 50 mph.
A draft report from city staff and Johnson Engineering will be forthcoming soon. It will also look at passing lanes.
