Navigating Miami's Toll Roads: A Complete Guide

Miami-Dade County operates an extensive network of toll roads and expressways managed primarily by the Florida Department of Transportation (FDOT) and the Miami-Dade Expressway Authority (MDX). Most tolls are collected electronically via SunPass or Toll-By-Plate (where a bill is mailed to the registered owner), as cash booths have been largely phased out.

Major Toll Facilities

1. Florida's Turnpike (SR 91) / Homestead Extension (SR 821): The backbone of the system, running north-south through the county. The Homestead Extension continues south toward the Florida Keys.
2. Dolphin Expressway (SR 836): Critical east-west artery linking Miami International Airport, downtown, and the Turnpike.
3. Palmetto Expressway (SR 826): While the main lanes are free, the SR 826 Express Lanes are dynamically tolled.
4. Don Shula Expressway (SR 874): Connects the Turnpike to the Palmetto in southwest Kendall.
5. Snapper Creek Expressway (SR 878): Short east-west link between SR 874 and US 1 in South Miami/Kendall.
6. Gratigny Parkway (SR 924): East-west connector in north Miami-Dade between I-75 and the Palmetto.
7. Port of Miami Tunnel: Fixed toll for access to the seaport from Watson Island/MacArthur Causeway.
8. I-95 Express Lanes & I-75 Express Lanes: Dynamically priced lanes on the interstates.

Tips for Drivers

• Get a SunPass Mini (sticker transponder) for the lowest rates; it works statewide.
• Rental cars often have toll programs with daily convenience fees—check your agreement.
• Unpaid Toll-By-Plate invoices incur significant administrative fees; pay promptly online.
