The Florida Department of Transportation (FDOT) is replacing the NASA Causeway Bridge over the Indian River to support future growth and improve public and commercial mobility. The current NASA Causeway consists of twin bascule bridges constructed in 1964, which are being replaced with new twin high-level bridges that will provide improved movement for oversized vehicles to launch sites. 

The NASA Causeway Bridge is being reconstructed under a partnership between the FDOT, NASA, and Space Florida. The State of Florida secured a $90 million Infrastructure For Rebuilding America (INFRA) Grant from USDOT. The grant will help to provide part of the funding needs for this bridge project as well as the widening of Space Commerce Way. 

With a taller and wider fixed bridge, spanning 4,025 feet over the Indian River Lagoon and rising 65 feet above the water, the new NASA Causeway Bridge will enhance the accessibility of this corridor, which includes Kennedy Space Center and the Cape Canaveral Spaceport.

In June 2023, the eastbound bridge was opened to the public. In March 2025, the new westbound bridge was opened to the public, marking the completion of both bridges. The project is marked completion March 2025.
