MDX Related Questions
Who is MDX?
The Miami-Dade Expressway Authority (MDX) is a State of Florida public agency created in 1994 by the Florida Legislature and the Miami-Dade County Commission. MDX has the responsibility to operate, maintain, improve and expand five expressways in Miami-Dade County: SR 924 (Gratigny Parkway), SR 112 (Airport Expressway), SR 836 (Dolphin Expressway), SR 874 (Don Shula Expressway), and SR 878 (Snapper Creek Expressway).
Why was MDX created?
MDX was created to ensure that tolls collected on its system would remain in the county and be reinvested on the MDX system. Prior to MDX, tolls collected would be sent to Tallahassee and then redistributed throughout Florida. Improvements on MDX roads are funded by the very users that experience them.
Who makes up MDX?
MDX is governed by a 9-member volunteer board appointed by the Governor and the Miami-Dade County Commission. There is a professional staff which establish near term and long term work programs.
How are MDX and its projects funded?
MDX is entirely funded by toll revenues collected on its system. No funding is received from gas, property nor the half-penny sales tax. It is a user-funded system, and revenue collected is reinvested on system-wide improvements in the form of expressway extensions, new lanes and ramps, roadway maintenance, providing greater mobility and connectivity in the South Florida area.

Will I get one consolidated invoice for all my toll trips in the State of Florida?
In June of 2108, MDX consolidated back-office operations with the Florida Turnpike (FTE) and the Tampa Hillsborough Expressway Authority (THEA). As such, you will receive a consolidated Toll-by-Plate invoice for transactions from MDX FTE, and THEA.
