Miami’s Signature Bridge has been one of the hardest civil jobs in the Southeast, and it’s finally taking its intended shape over downtown. The design-build reconstruction of I-395, SR 836 and I-95 carries a price tag near $840 million and now targets completion in late 2027, years past the original schedule.
Project Scope
The centerpiece is a set of soaring, spider-like arches springing from a single foundation over Northeast Second Avenue and Biscayne Boulevard. The work also stacks an upper deck of traffic over State Road 836 and the Miami River and adds a lane to the northbound entrance of I-95. FDOT and the Greater Miami Expressway Agency own the project; an Archer Western and de Moya Group joint venture is building it. Fabricating and erecting the arches has been the schedule’s pinch point, a painstaking sequence of segment casting and post-tensioning.
Why It Matters
The old I-395 viaduct walled off Overtown from downtown for decades. The new span opens the ground plane underneath for a park while moving more traffic overhead. It’s also a case study in how aggressive an urban signature bridge can get before constructability catches up with the renderings, a lesson other cities chasing iconic infrastructure are watching closely.
