About

As of April 4, 2023, all work was completed and this project was final-accepted from the contractor.

This project reconfigured the I-75 / SR 56 interchange between CR 54 and Cypress Ridge Boulevard in Pasco County. The former diamond interchange was modified and converted to a diverging diamond interchange (DDI). The main change was to diverge (cross) SR 56 traffic to the left side of the road through the interchange, and then cross vehicles back over to the right side of the road on the opposite side of the interchange. The improvements help alleviate traffic congestion at the interchange to reduce travel time for motorists in this rapidly growing area.

  • Construction cost includes original construction contract amount plus approved contract changes. It does not include inspection oversite.
