The Superior Construction–MasTec Civil Joint Venture was selected as the lead Contractor, with KCA serving as the lead Designer, for this $367 million project. This will be FDOT’s first MPDB project delivery. The project reconstructs the I-4 (SR 400) mainline and improves the SR 417 and US 192 interchanges to increase capacity, enhance mobility, and support long-term corridor performance.

Major elements include new express lane direct-connect ramps; construction of new bridges and retaining walls; reconstruction and widening of ramps and the collector-distributor system; and milling and resurfacing of SR 417. The scope also expands stormwater ponds, installs new drainage systems, and rehabilitates cross drains, while preserving the I-4 median for future high-speed rail.

Additional corridor-wide improvements include new lighting, signing and pavement markings (S&PM), Intelligent Transportation Systems (ITS) and Connected and Automated Vehicle (CAV) infrastructure, noise walls, and permanent tolling facilities. The project also includes construction of a new All-Electronic Tolling (AET) facility and demolition of the existing Celebration Plaza toll plaza. Aesthetic enhancements, landscape opportunity planning, and replacement of deficient elements complete the work, positioning the corridor for future operations and growth.
