MIAMI (AP) - The Homestead Extension of Florida's Turnpike is going cashless.

Starting Feb. 19, drivers who don't have a SunPass will receive a monthly bill with a service charge tacked on. Turnpike officials say the new system will help speed traffic and improve road safety.

 There are 37 toll plazas on the 47-mile roadway, which stretches from Miramar to Florida City.

Officials say motorists may encounter a mixture of cash booths and electronic toll booths as the roadway is converted to the cashless system.

Billing for non-SunPass users is done through a Toll-by-Plate system in which cameras snap pictures of license plates as vehicles pass by.

Turnpike officials say about 80 percent of toll transactions on Turnpike Extension are done via SunPass.
