About the construction project


Construction of Florida’s first Diverging Diamond Interchange (DDI) begins in August, 2015 at I-75 and University Parkway in Sarasota/Bradenton. This innovative design offers a proven solution for improving overall traffic operations and safety for motorists, cyclists and pedestrians. In addition, studies of existing DDIs show a significant reduction of major crashes, an overall reduction in delay times, and an increase in overall capacity.


Improvements being made as part of this project consist of constructing a diverging diamond interchange, adding an auxiliary lane on northbound and southbound I-75, constructing new bridges on I-75 over University Parkway, widening of University Parkway, widening of I-75 bridges over Errie Creek and Foley Creek, realignment of on-ramps and off-ramps at I-75/University Parkway, addition of ponds, drainage improvements, new lighting and signalization, construction of a noise wall on the west side of I-75, sidewalks, bike lanes, and pedestrian walkways.
