Connected communities. Improved economies. Enhanced livability.

These benefits are embodied by Central Florida's most extensive transportation project to date: the Interstate 4 (I-4) Ultimate Project. At $2.3 billion, it is the largest public-private partnership (P3) in Florida Department of Transportation (FDOT) history. Construction on the project began in 2015 and is scheduled to be completed by 2021.

Known as the backbone of Central Florida's surface transportation, the I-4 corridor provides a crucial link between Tampa on the west coast and Daytona Beach on the east coast, passing through the Orlando metro area. It connects some of the state's most popular travel destinations including SeaWorld, Universal Orlando Resort and Walt Disney World.

With increasing resident and visitor populations, FDOT has planned for years to overhaul I-4 in order to relieve congestion and create better connections and accessibility for the traveling public.

This project consists of approximately 21 miles of reconstruction on mainline I-4 in Orange and Seminole counties. It includes reconstructing 15 major interchanges, adding 85 extra lane-miles of mainline roadway, increasing capacity with additional auxiliary and turn lanes, and constructing more than 145 bridges (56 new, 68 replacement and 13 modified). One key element to reducing congestion is adding four express lanes in the median of the existing facility, while general-use lanes are being redone along the outside.

In April 2014, FDOT selected I-4 Mobility Partners to design, construct and maintain the I-4 Ultimate project. The team is comprised of an engineering joint venture and a separate construction joint venture. HDR and Jacobs Engineering Group comprise the engineering side while the construction side includes Skanska Infrastructure Development and John Laing Group.

Our team took a unique, multi-faceted approach to this project, starting with a proposal-compliance matrix that led to developing alternative designs and co-locating with the construction joint venture to improve collaboration. A task force was created to consider the owners' potential technical enhancements and an in-house economist was asked to build a cost-benefit model. In the end, the I-4 Mobility Partners team was selected as the best-value proposer for design of the I-4 Ultimate.

Our design joint venture is responsible for final I-4 Ultimate project designs, including roadway and traffic controls, drainage, structures, intelligent traffic systems, signing and signalization, lighting and landscaping/aesthetics. HDR | ICA is providing operations and maintenance services during the construction phases of the project and will continue through the 40-year concession period and beyond.

By utilizing variable tolls throughout the day, and including direct connections to State Route 408, a major east-west toll facility in downtown Orlando, these new, managed lanes will help facilitate better traffic flow throughout the region.

The I-4 Ultimate project will also incorporate the highest level of sustainability, attained through application of the Envision® rating tool. This system is being used to incorporate sustainable solutions during project development. In following this process, our team provides a holistic approach, accounting for environmental and economic benefits to the community and delivering a facility that will be sustainable through the 40-year concession and after. The I-4 Ultimate anticipates being America's first-ever Envision®-certified platinum highway.

Going above and beyond the improvements to I-4, FDOT desired a way to showcase the area and its vibrant culture. I-4 will be a premier, one-of-a-kind, signature corridor that will exemplify the Central Florida experience through its reflection of the region's history, landscape and unique community character. Furthering the benefits, this project embodies artwork from local artists, which are included in the design. Works range from monuments to murals to sculptures. Pedestrian bridges are also being constructed to accommodate foot traffic and provide a path over I-4, south of Maitland Boulevard and Kirkman Road, which creates a connection to Universal Orlando Resort.

Once finished, the I-4 Ultimate Project will significantly improve congestion, safety and accessibility in the region while simultaneously enhancing the lives of residents throughout Central Florida.
