The Florida Department of Transportation has been given approval by Gov. Rick Scott and the state Legislature to begin the procurement process for the $2.1 billion Interstate 4 Ultimate Project. The 21-mile rebuild of the interstate involves building 56 new bridges, replacing 68 bridges and reconstructing 15 interchanges. It would take 26 years to finish the 21 miles of I-4 improvements if the state tried to do the work using a traditional pay-as-you-go approach, but it's expected to take five to six years to complete with a private-public partnership. FDOT hopes to have funding close by the summer of 2014.
