The city Miami is going through one of the urban transformations the most ambitious in its recent history. The Signature Bridge, a monumental structure, rises in the heart of the city center This will not only change the landscape of the southern metropolis Floridabut also aims to solve a structural problem: the traffic congestion caused by decades of outdated highways.
The initiative is integrated into the modernization of the I-395/SR 836/I-95 corridor and aims to improve mobility, traffic safety and connectivity between historically separate neighborhoods.
The work includes a bridge with six arches and a maximum height of 330 feet (over 100 meters)what will redefine this Skyline from Miamias Connecting Miami, the official name of the megaproject, describes in detail.
As of December 2025two of these arches are already finished and the tallest one has its 86 prefabricated segments.
The development is part of a larger plan that includes a double-decker elevated highway across the city SR836designed to order the streams in between I-395, I-95 and the MacArthur Causeway.
As part of this, all foundations of the new I-395 main road were completed and the prefabricated road segments were laidEven on sensitive sections such as railway tracks. Parallel to that Work on SR 836 is progressing. with large cranes assembling columns, beams and slabs for the double-story structure.
The project is the result of an alliance between the Florida Department of Transportation (FDOT)the Greater Miami Highway Agency and the construction consortium Archer Western–de Moya Group Joint Venture, responsible for coordinating the work.
Beyond the visual impact, The intervention aims to address historical bottlenecks. According to the authorities responsible for the major project, these improvements will allow for smoother traffic, redesigned ramps and safer access routes This would benefit more than 100,000 vehicles per day traveling through the corridor.
Add to that new drainage systems and road elevation to control high tide flooding, an important point in a coastal city like Miami.
One of the most innovative aspects of the megaproject is what will happen under the elevated highway. Over there The Underdeck/Heritage Trail program will develop approximately 55 acres of public space.
The plan includes Pedestrian and cycle paths, green spaces and recreational areas that will connect neighborhoods like Overtown to Biscayne Bay.
The extent of Miami’s great work is also reflected in the cost. The investment already exceeds $866 million and completion is scheduled for the end of 2029.
While the work continues, Authorities warn of nighttime closures and temporary diversionsInformation constantly updated through official project maps.
