I-4 at SR 408

UPDATED: NOVEMBER 16, 2015 1:36 PM — Contractors are getting more deeply into construction of the I-4 Ultimate project, which began in February and will take six years. The project involves total reconstruction and widening of 21 miles from Kirkman Road in Orange County to just east of State Road 434 in Seminole County.

The majority of construction is currently in the right-of-way to allow for utility relocations, drainage improvements and creating safe areas for work, a Florida Department of Transportation spokesman said.


Two major long-term traffic shifts occurred in October on westbound I-4. The first major traffic shift opened near Lake Ivanhoe and the second long-term traffic shift opened near the Formosa Avenue overpass.

As precursors to larger changes, both traffic shifts involved constructing temporary westbound travel lanes. In the next several months, the eastbound lanes in these two areas will shift to the old westbound lanes. These future traffic shifts will create work zones on the east side of the interstate. In these work zones, workers will begin constructing the new eastbound general use lanes.

The FDOT says it is committed to getting drivers where they need to go by maintaining the same number of lanes during peak travel times that were available prior to construction. Lane closures will be limited mostly to nighttime hours, beginning as early as 8:30 p.m. and ending as late as 7 a.m. The contract does allow the contractor to request additional closures. Each request will be evaluated on a case-by-case basis, says the FDOT, which has final approval on all requests.

Construction will add two toll express lanes in each direction, while maintaining free general use lanes as a way of easing traffic flow, transportation officials say.

More than 140 bridges will be replaced and widened and 15 major interchanges reconfigured.

Once the project is done, the FDOT promises a much smoother run for a corridor whose average traffic ranges from 134,000 to 194,000 vehicles a day.
