Interstate 4 Ultimate Improvement Project

Public-Private Partnership, Design-Build-Operate-Finance-Maintain Model

Highlights

Priced at roughly $2.3 billion, the I-4 Ultimate project will reconstruct 21 miles of roadway through Florida’s Orange and Seminole counties, installing four dynamic-toll express lanes in the median and rebuilding general use lanes the length of the corridor. Fifteen major interchanges will be reconstructed; 13 bridges will be widened; 74 bridges will be replaced; and 53 bridges will be added. Construction began in 2015 and is scheduled for completion in 2021.

When the project was awarded in April 2014, it was the largest public-private partnership in the country. Florida Department of Transportation selected I-4 Mobility Partners (I4MP) as the P3 concessionaire. Several industry leaders formed the I4MP team to design, build, operate, finance and maintain the project through a 40-year P3 concession agreement.

Members of the I4MP team include: Skanska Infrastructure Development (equity member); John Laing Investments Limited (equity member); SGL Constructors, which is a construction joint venture comprised of Skanska as the lead JV partner, Granite Construction Company and the Lane Construction Corporation; and with operations and maintenance being led by Infrastructure Corporation of America (HDR|ICA).

HDR oversees design as the lead partner in a joint venture with Jacobs Engineering Group. Our team is delivering all roadway engineering and design for traffic control, drainage, structures, intelligent traffic systems (ITS), signing, signalization, lighting, landscaping, aesthetics and utility relocations. Florida DOT selected I4MP as the concessionaire based in part on alternative technical concepts developed by our design team.

The department had planned for years to overhaul the corridor to relieve traffic congestion, enhance safety and create better connections. We are helping the department advance its plan while incorporating alternative modes of transportation, sustainability, resiliency and low impact design—all with extensive stakeholder input so facilities have wide community support.

This portion of I-4 in central Florida provides a crucial link between Tampa to the west and Daytona Beach to the east. It also brings travelers to some of the state’s most popular destinations, including SeaWorld, Walt Disney World and Universal Orlando Resort. When complete, the project will provide a signature corridor that boasts bold landscaping, accent lighting, illuminated fountains and enhanced aesthetics. Location-specific features such as murals and sculptures will reflect the surrounding communities.

Innovative design combined with innovative delivery is yielding a visually appealing, modern and multimodal facility with much greater capacity, on an accelerated schedule.

Connect Communities, Improve Economies and Enhance Livability

The goal is to create a signature corridor that connects communities, improves economies and enhances livability. Our design team is making this possible through collaboration with the construction joint venture.

Among our 25 accepted ATCs is a pedestrian bridge across Kirkman Road, which improves non-motorized transportation access between the entrance to Universal Studios Resort and many nearby hotels. It thereby reduces automobile traffic at a busy intersection while attracting tourism and enhancing safety for pedestrians and motorists — contributing to all three objectives.

“In a design-build project, ATCs are very important because they help bring innovation,” said Larry Low, HDR Principal Project Manager. “Our team identified this additional bridge early on as an important infrastructure piece to connect the pedestrian community, which is a significant theme for sustainable transportation infrastructure.”

Florida DOT adopted many additional, sustainable elements, emphasizing the deployment of multimodal facilities in concert with resilient, modern roadway infrastructure. For example, noncontiguous bikeways that existed in patches along the 21-mile corridor will be lengthened through this project and linked by new trails and designated bike routes. The project will also promote use of existing mass transit by allowing LYNX bus service to travel toll-free on the new express lanes.

Among the project’s most innovative and unique features is the so-called bridge district, a community gathering area proposed beneath the I-4 overpass at Church Street in Orlando. The proposed name is “Under I” park. It will be a front yard for the community, a place for connection and a source of enhanced livability that is fully ADA accessible. “By incorporating public space for community social events into a transportation corridor, the I-4 Ultimate Improvement Project is able to increase the value and usage of the property,” said John Lazzara, HDR Transportation Engineer and Sustainability Lead.

Our design innovations contributed to the project being certified in January 2017 with an Envision Platinum rating from the Institute for Sustainable Infrastructure, becoming HDR’s sixth Envision-verified project and reaffirming its leadership in sustainable transportation design.

Operations, Maintenance and Safety Patrols

HDR also helps protect the project throughout construction.

HDR|ICA is providing operations and maintenance services for routine roadway maintenance, emergency management, bridge inspection and service patrols, with a focus on maximizing safety, reliability and roadway availability within the project area. Our services include daily safety service patrols (branded “Road Rangers” by FDOT) for the length of the corridor to aid stranded motorists and keep travel lanes clear of potential hazards.

Our asset maintenance team also manages maintenance programs for services within the corridor right of way, including: mowing services; sign repair; impact attenuator repair; graffiti removal and guardrail repair.
