Terms and Conditions

The Miami-Dade Expressway Authority (MDX) is a user funded transportation agency dedicated to improving the mobility of people, goods and the economy in Miami-Dade County. The agency does not receive money from gasoline taxes or other tax revenue to maintain, operate and enhance its expressways. The not-for-profit agency was created in 1994 by the Miami-Dade County Commission to establish local control of toll revenues collected on the five Miami-Dade County expressways, and to ensure that the toll revenue collected would be reinvested to improve transportation locally. The MDX expressway system consists of five of the most heavily traveled expressways in Miami-Dade County:

  • SR 112/Airport Expressway
  • SR 836/Dolphin Expressway
  • SR 874/Don Shula Expressway
  • SR 878/Snapper Creek Expressway
  • SR 924/Gratigny Parkway

Frequent Driver Rewards Program

The "Frequent Driver Rewards Program" (FDRP) was established by the Board of Directors of MDX to make possible for MDX to give back directly to the frequent users of our 5 expressways. This will translate into paying a lower toll. MDX created the Frequent Driver Reward Program to provide relief to those frequent commuters that drive the MDX expressways.

MDX customers that pay $100 on tolls on the MDX’s Expressways during the period of July 1st through June 30th and meet eligibility requirements of the program, can receive a refund on the tolls paid for the use of MDX’s Expressways. In the Fall of every year, the MDX Board of Directors of MDX decides as to what percentage will be refunded to the customer. To register you must have a SunPass® account up to date and in good standing and customers must register each transponder into the program. In order to obtain a reward, each transponder must meet the MDX FDRP eligibility requirements.

MDX Frequent Drive Reward Program participants, who have previously registered, will automatically be enrolled but are encouraged to log in to their account to ensure the information, especially the mailing address, is current.
