The I-4 Ultimate Improvement Project is a P3 effort involving reconstruction and expansion of a 21-mile stretch of I-4 that moves into the heart of Orlando, Fla. Work on the project began in 2015, and the project limits run between Orange County and Seminole County. Due to the scope of the project, crews had to follow a strict traffic management and safety protocol policy in order to keep both traffic flowing during construction and minimize traffic- and work-related incidents. At the time of Roads & Bridges' visit to the I-4 worksite, the Grand National Drive Overpass was open to traffic and crews were preparing to close up the summer season.
