I-4 Ultimate Improvement Project

Interstate 4 (I-4) Design Build

I-4 Ultimate Improvement Project

Priced at roughly $2.3 billion, the I-4 Ultimate project will reconstruct 34 kilometers (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 (PPP) in the country. Florida Department of Transportation (FDOT) selected I-4 Mobility Partners (I4MP) as the PPP concessionaire. Several industry leaders formed the I4MP team to design, build, operate, finance and maintain the project through a 40-year PPP concession agreement.

Members of the I4MP team include: Skanska Infrastructure Development (equity member); John Laing Investments Limited (equity member); SGL Constructors (SGL), 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 is the lead design partner in a joint venture with Jacobs Engineering Group. Our team is delivering all roadway engineering and design for traffic control, drainage, bridges, structures, intelligent traffic systems (ITS), signing, signalisation, lighting, landscaping, aesthetics and utility relocations. The Australian-based bridge design team worked closely with the US -based bridge team to produce the bridge designs, with the difference in time zones ensuring the client received  24/7 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 travellers to some of the Florida’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. The goal is to create a signature corridor that connects communities, improves economies and enhances livability. 

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.
