Electronic tolling will be introduced in six expressways in South Florida starting with Gratigny Parkway and followed by Don Shula, Snapper Creek, Dolphin, Airport and Homestead Extension.

The open-road tolling involves collection of tolls electronically using either SunPass transponders or video-billing systems, which take photographs of vehicles and send bills to the owners.

The electronic tolling for all the expressways will be complete by 2013.
