The Florida Department of Transportation (FDOT) has awarded a contract to WSP | Parsons Brinckerhoff to design the reconstruction and widening of a nine-mile segment of I-4 in Seminole County.

The project, which extends from one mile east of SR 434 to east of US 17/92, involves reconstruction and widening of I-4 from the existing six-lane divided interstate to a 10-lane divided interstate. The concept design proposes the addition of two new barrier-separated express lanes in each direction, for a total of 10 lanes. The scope also includes reconstruction of several interchanges and arterial roads at those interchanges in order to relieve the traffic that backs up all the way to the interchanges.

The project is part of FDOT’s I-4 Ultimate and Beyond the Ultimate widening projects that the agency expects will transform the region by connecting communities, improving the economy and enhancing livability in the Orlando metropolitan area.

Under its contract, WSP | Parsons Brinckerhoff will be the prime designer responsible for overall project management; design of the roadway, drainage and structures; ITS and traffic design; public involvement; utility coordination; and express lane design. The firm will advance the design to approximately 50 percent completion in order to obtain all necessary permits and establish right–of-way requirements.
