Construction continues on the $74.5 million project to convert the busy diamond interchange linking Interstate 75 with University Parkway in Sarasota, Florida to a large diverging diamond (DDI). Work runs through fall 2017 on what is touted as the state’s first DDI.
In addition to building new overpasses for Interstate 75 above University Parkway, the extended ramps to the east-west arterial, and the ten-lane wide DDI, construction also adds auxiliary lanes to the freeway south to Florida 780 (Fruitville Road). We drove through the project area over the weekend:
Upon completion, two-lane off-ramps will take motorists from the freeway to a five-lane separation for the parkway west to Sarasota and east to Lakewood Ranch.
The new spans will accommodate 12 overall lanes between the respective on and off ramps below.
The construction zone is a regular location of traffic back-ups due to the S-curves currently in place.
The freeway will accommodate eight overall lanes between Exits 210 and 213 upon completion of the project.
Displayed as County Road 610 along I-75, University Parkway is unnumbered along its route between the suburban Lakewood Ranch community to the east and by The Mall at University Town Center and Sarasota-Bradenton International Airport (SRQ) to the west.
Two lanes will separate from the mainline ahead of a five-lane partition for the DDI.
University Parkway straddles the Manatee and Sarasota County line west to U.S. 301.
