Description

The iROX project involved the expansion of I-75 through Collier and Lee counties in Florida. The project had several components:

  • Resurfacing and widening of 30 miles of I-75 from four lanes to six lanes from Golden Gate Parkway in Collier County to Colonial Blvd. in Lee County; addition of 12-foot travel lane and 10-foot paved shoulders
  • Reconstructing the Immokalee Road interchange in Collier County
  • Coordination with adjacent projects in the corridor including the Regional Traffic Management Center/ITS project, Lee County Estero Parkway extension bridge, I-75/Bonita Beach Rd interchange and I-75 from Colonial Blvd. to SR 82 widening

The six lanes opened one year ahead of schedule, and the I-75/Immokalee Road Interchange opened nine months ahead of schedule.

Financial Status

Closed. The joint venture began receiving payments from FDOT in October 2007, at first on a monthly basis and then on a quarterly basis after August 2008 when the initial funding ran out. Approximately $380 million was paid out during the project's construction period and $78 million after completion. The last payment to the contractor occurred in October 2011.

Innovations

  • Project would have been procured as nine separate design-bid-build projects when originally conceived, but when Florida's P3 law was amended in 2004, relaxing legislative approvals, a DBF approach was pursued.
  • First DBF project in the state.
