The rebuilding of 21 miles of Interstate 4 in Florida has received the prestigious Envision Platinum recognition from the Institute for Sustainable Infrastructure (ISI) for its sustainability efforts of environmental, social and economic impact on the community.
The I-4 Ultimate Project involves the reconstruction of 21 miles of roadway infrastructure from west of Kirkman Road in Orange County. It involves the addition of four new variable toll express lanes and the reconstruction of 15 major interchanges, which includes widening 13 bridges, replacing 74 bridges and adding 53 new bridges.
When complete, the project will provide a visually appealing signature corridor with bold landscaping, accent lighting, enhanced bridge architecture and other aesthetic features. The project is expected to transform the region by better connecting communities, improving the local economy and enhancing livability for residents.
Envision sustainable infrastructure rating system.
This is the first project in Florida to receive recognition from ISI’s Envision sustainable infrastructure rating system. It recogniises the efforts of the entire I-4 Ultimate Improvement team to protect the environment from water to wildlife to air quality, while creating a signature corridor for the entire region.
The I-4 Mobility Partners (I-4MP), the public-private partnership (P3) rebuilding Interstate 4 through Central Florida, earned the Envision Platinum award for its ongoing programs to minimise environmental impacts, including relocating protected wildlife, using efficient machinery, controlling stormwater runoff, planting non-invasive vegetation, and recycling 99% of the concrete and steel removed from roads and bridges. The project also facilitates the use of alternative transportation by integrating rail projects and improving pedestrian crossings and connections with bike trails.
Several industry leaders formed the I-4MP team to design, build, finance and operate the project through a 40-year P3 concession agreement with a total design and construction cost of $2.32 billion dollars.
The members of the I-4MP team include:
Created in 2012 through collaboration between ISI and the Zofnass Program for Sustainable Infrastructure at Harvard University Graduate School of Design, the Envision system rates the impact of sustainable infrastructure projects as a whole.
The system measures sustainability in five categories: Quality of Life, Leadership, Natural World, Resource Allocation, and Climate and Risk. These key areas contribute to the positive social, economic and environmental impacts on a community.
The I-4 Ultimate Project received high scores in the Quality of Life, Leadership, and Natural World categories.
