I-4 and Florida’s Turnpike Mainline (Direct Connect) Design-Build

I-4 and Florida’s Turnpike Mainline (Direct Connect) Design-Build Overview

Orange County, FL

In partnership with Superior Construction, GAI is providing design services for this $85 million project that adds express lanes to a portion of Florida’s Turnpike mainline, as well as introduces new all-electronic tolling to the I-4/Florida’s Turnpike interchange—a vital access point to Central Florida’s tourist attractions. The centerpiece of the project is the design-build of a 2,000-ft, 13-span, prestressed concrete flyover ramp that directly connects I-4 Ultimate and Turnpike Express Lane systems (i.e., “I-4 Direct Connect”). The project also included milling and resurfacing, miscellaneous roadside improvements to the Turnpike Mainline between the Beachline Expressway (SR 528) and I-4, as well as the installation of all-electronic tolling. The project opened to traffic in early 2022.
