HDR will be the lead designer for the Florida Department of Transportation’s contract to construct a signature bridge and reconstruct 1.4 miles of interstate near Downtown Miami. The bridge is destined to become an icon and the largest precast concrete segmental arch bridge in North America. The cost for the entire project is $803 million, and it is being procured through a public-private partnership (P3) between FDOT and the Miami-Dade Expressway Authority (MDX).

Florida DOT awarded the contract to the joint venture Connecting Miami, which is comprised of Archer-Western and the de Moya Group. HDR is the JV’s engineer of record for the signature bridge, roadway and drainage design for the I-395 viaduct, and for 13 conventional bridges along the corridor. The design scope of work for the entire project also involves major improvements to the SR-836/I-395/I-95 interchange. Design will take 24 months, with construction commencing in late 2018. The bridge is expected to open in 2022.

Located near the eastern boundary of the project, the signature bridge will be named The Fountain, and it will span 1,025 feet across two busy roadways. Its largest arch will soar 325 feet above the ground and span 650 feet across, making it the third largest precast concrete segmental arch in the world, behind bridges in France and Australia.  The bridge’s sustainable design contributes to unlocking 55 acres beneath I-395, allowing for the creation of a linear park called the Heritage Trail, which will feature historic figures, fountains, parks and mixed-use areas.

Inclusion of the Heritage Trail reflects Miami’s desire to reconnect the Overtown community, which was divided some 60 years ago by the interstate’s construction. Additional sustainability features will foster a safer environment for pedestrians, cyclists and vehicular traffic.  Roadway improvements will solve mobility challenges that have inhibited traffic flow for many years. For example, the project is expected to reduce user delays by 81 percent system-wide. Both the community enhancements below I-395 and the highway-capacity improvements will benefit residents and visitors far beyond the project limits.

 “This presents an extraordinary opportunity to transform Miami, not only its skyline with the soaring arches of a signature bridge, but also by reconnecting communities divided half a century ago,” said HDR’s Bridges & Structures Director Pat Hickox. “We are extremely pleased to be part of the Connecting Miami team to make this great project possible.”
