By car, from Miami International Airport, follow signs to Coral Gables and Key West, which puts you on LeJeune Road, then Route 836 west. Take the Homestead Extension of Florida's Turnpike south (toll road), which ends at Florida City and connects to the Overseas Highway (U.S. 1). Tolls from the airport run approximately $3. Payment is collected via SunPass, a prepaid toll program, or with Toll-By-Plate, a system that photographs each vehicle's license plate and mails a monthly bill for tolls, plus a $2.50 administrative fee, to the vehicle's registered owner.
Vacationers traveling in their own cars can obtain a mini-SunPass sticker via mail before their trip for $4.99 and receive the cost back in toll credits and discounts. The pass also is available at many major Florida retailers and turnpike service plazas. It works on all Florida toll roads and many bridges. For details on purchasing a mini-SunPass, call or visit the website.
For visitors renting cars in Florida, most major rental companies have programs allowing customers to use the Toll-By-Plate system. Tolls, plus varying service fees, are automatically charged to the credit card used to rent the vehicle (along with a hefty service charge in most cases). For details, including pricing options at participating rental-car agencies, check the program website. Under no circumstances should motorists attempt to stop in high-speed electronic tolling lanes. Travelers can contact Florida's Turnpike Enterprise for more information about the all-electronic tolling on Florida's Turnpike.
The alternative from Florida City is Card Sound Road (Route 905A), which has a (cash-only) bridge toll of $1. SunPass isn’t accepted. Continue to the only stop sign and turn right on Route 905, which rejoins the Overseas Highway 31 miles south of Florida City.
Except in Key West, a car is essential for visiting the Keys.
