Florida’s First Diverging Diamond Interchange

America’s Largest Diverging Diamond Interchange

On Thursday, July 23, District One held a preconstruction open house for the I-75/University Parkway Diverging Diamond Interchange (DDI). This project is the first DDI in Florida. Over 250 people and numerous media outlets attended the two-hour event. Attendees were able to watch a video presentation, view designs, and have their questions answered by FDOT staff, consultants, and the contractor.

In addition to the DDI, the project includes:

  • Adding an auxiliary lane to the existing three lanes each way for regular northbound and southbound traffic on I-75. The new auxiliary lanes will only be between Fruitville Road and University Parkway and are intended for traffic only intending to go from one exit to the next.
  • Construction of new overpasses at University Parkway.
  • Widening University Parkway from Cattlemen Road/Cooper Creek Boulevard west of the interchange to Market Street/Lake Osprey Drive in Lakewood Ranch.
  • Widening the I-75 bridges over Errie Creek and Foley Creek.
  • Realignment of the on- and off-ramps at the interchange.
  • Construction of a noise-buffering wall on the west side of I-75 between Fruitville Road and Nathan Benderson Park.
  • Pond and drainage improvements.
  • New sidewalks, bike lanes and pedestrian walkways.
  • New lighting and traffic signals.

The $74.5 million project begins August 3, 2015 with completion mid-September 2017, just in time for the World Rowing Championships held at Benderson Park in Sarasota. The contractor for this project is Prince Construction.
