The I-4 Ultimate Improvement Project is a planned makeover of Interstate 4 in Central Florida. The $2.3 billion construction project spans 21 miles, from west of Kirkman Road in Orlando to east of State Road 434 in Longwood.
The project officially got underway on Feb. 1, 2015, and is expected to be completed by 2021. Updates include widening I-4 to up to 10 lanes in some areas, including 4 express toll lanes.
