Summer 2025 Construction Update For Miami's 325' Tall Signature Bridge As The Arches Take Form On 'The Fountain'

Miami’s Signature Bridge, known as The Fountain, is entering a new phase of construction as the project’s iconic arches begin to rise above I-395, offering a first glimpse of the monumental structure set to redefine the city’s skyline. The six-arch bridge, designed as both a transportation link and architectural statement, is progressing steadily according to the Florida Department of Transportation. Once complete, it will improve traffic flow between I-95, I-395, and SR 836 while creating an iconic new visual gateway into downtown with six sweeping arches. Set to span 1,025’ over NE 2nd ave. and Biscayne Boulevard, the largest of the six-arches will reach 325’ tall and 650’ wide. Several key segments of the arches are now being installed, with full vertical completion anticipated in 2027.

The Signature Bridge is the centerpiece of a larger infrastructure initiative that includes reimagining the space beneath it. Known as The Underdeck, this 55-acre public park will stretch from Overtown to downtown, reconnecting neighborhoods long divided by highway infrastructure. Planned amenities include green space, pedestrian paths, public art, and event areas. The broader design-build effort is being led by the Archer Western–de Moya Joint Venture in collaboration with FDOT and the City of Miami. More than just a road project, the Signature Bridge aims to blend mobility, urban design, and community revitalization into a single, transformative vision for Miami.

The Signature Bridge project has had its fair share of drama. In July 2018 the bridge was awarded a Notice to Proceed following an April 2018 hearing where the State of Florida Division of Administration Hearing ruled in favor of FDOT after bridge advocate and former Miami City Commissioner Marc Sarnoff filed a lawsuit alleging that FDOT violated their 2013 settlement agreement via their handling of bids to design and build the bridge by manipulating scoring to allow the Archer Western and The de Moya Group's proposal to win. In May 2018 a Judge ruled in favor of FDOT to allow them proceed with the winning design.

Judge Rules Florida Department of Transportation Can Proceed With "The Fountain" Signature Bridge

A judge has ruled to allow the Florida Department of Transportation (FDOT) to proceed with the winning design for Downtown Miami's proposed $802 million Signature Bridge. The winning design is known as "The Fountain" designed by Archer Western and The de Moya Group. In an April hearing, the State of Florida Division of Administration Hearing ruled in favor of FDOT after bridge advocate and former Miami City Commissioner Marc Sarnoff filed a lawsuit alleging that FDOT violated their 2013 settlement agreement via their handling of bids to design and build the bridge by manipulating scoring to allow the Archer Western and The de Moya Group's proposal to win. Another design by contractors Fluor, Astaldi and MCM, which finished in second, was allegedly the favorite design by community representatives. The court ruled that Fluor-Astaldi-MCM failed to prove that "The Fountain" was chosen due to corruption. The legal action delayed the groundbreaking which was supposed to commence in 2017 and be completed in 2022. The Signature Bridge is expected to cost $802 million with $626 million in funds provided via the State of Florida including state motor fuels tax, vehicle license fee, and documentary stamp collections; and $186 million being funded via MDX toll revenue bond proceeds.
