Card Sound Toll Authority


The Card Sound Toll Authority is primarily responsible for operating the Card Sound Bridge toll booth in North Key Largo. The department also maintains the toll facilities and grounds and mows and cuts brush on the right of way along Card Sound Road.

Tollbooth Being Converted to All-Electronic Tolling System

The last hand-collected toll was Thursday, Aug. 31, 2017, at midnight. The tollbooth has been demolished.

During construction of the All-Electronic Tolling System, no tolls will be collected.

Construction was delayed due to Hurricane Irma. The new electronic system is scheduled to begin operation June 2, 2018. The new toll only will accept SunPass or drivers will receive a bill in the mail by TOLL-BY-PLATE.

The new toll rates have not been set yet. This will be done at the upcoming March 21, 2018 Monroe County Board of County Commissioners meeting at the Murray Nelson Government Center in Key Largo. There will be discounted rates for frequent commuters through the toll.
