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:

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

SunPass customers that incur a minimum of $250 per transponder in tolls on MDX's Expressways during the time frame of July 1st through June 30th are able to receive a cash back of 15% up to $300 per year on SunPass tolls paid.
