Transportation Projects

This project involved the complete reconstruction of I-4, including the construction of 144 new bridges, major upgrades to 15 urban interchanges, new Intelligent Transportation Systems (ITS) within the FDOT right-of-way, and 21 miles of new tolled express lanes, two eastbound and two westbound.


Central 70 is one of the most impactful projects of our generation, projected to result in $18 billion of new economic activity in Colorado by 2040. Consisting of reconstructing 10 miles of I-70, this $1.2 billion project was initiated to address local and regional congestion and to revitalize the local economy.


RS&H's team provides complete expertise for all aspects of San Antonio’s mobility goals, from urban planning and design to placemaking to preliminary engineering and final design. Our approach identified various unique approaches and enhancements to this study.


RS&H was tasked by environmental agencies to design the ends of the bridge to minimize impacts to coastal wetlands in order for the project to be permitted. We had the challenge of designing bridge bent locations to avoid a submerged aquatic vegetation area under part of the bridge.


The new six-lane divided highway and bridge now serves as a critical hurricane evacuation route, a multi-modal transportation alternative including automobile, bicycle, pedestrian, and public transit accommodations, and includes an ADA-accessible canoe launch area.
