I-75 Roadway Expansion (iROX)
The $430.5 million Interstate 75 Roadway Expansion (iROX) project is the largest roadway project in the history of the Florida Department of Transportation (FDOT). When the FDOT selected ACCI/API as the design-build-finance contractor, it marked the first time the FDOT entered into a public-private partnership (P3). The project involves widening 30 miles of I-75 from four lanes to six, reconstructing 20 bridges, building four new bridges, creating 23 stormwater lakes and installing six noise barriers. We are providing design and construction phase services.
The design-build approach is credited with making an aggressive design and construction schedule possible. Our design engineers served as on-site construction engineers in order to advance decision making, make changes to the design and expedite changes without interrupting construction. Our construction phase services team provided independent verification of plans and managed requests for additional information, design concerns and construction. This approach proved particularly useful when completing one of the most challenging aspects of the project – securing environmental clearances and obtaining stormwater permits within nine months of contract execution.
The result is a quality project with savings in cost, time and administration. Six lanes opened in December 2009, one year ahead of schedule, and the I-75/Immokalee Road Interchange opened in May 2010, nine months early.
