Miami’s Signature Bridge: With Final Height Approved, Cranes Will Now be Installed

The Federal Aviation Administration approved this week the final height of Miami’s Signature Bridge. The tallest of the six arches planned will rise 330 feet above the ground. The length of the bridge will be 1,025 feet. See below each of them:

• Arch 1 – 180 feet above the ground, 186 feet above sea level
• Arch 2 – 230 feet above the ground, 237 feet above sea level
• Arch 3 – 180 feet above the ground, 187 feet above sea level
• Arch 4 – 250 feet above the ground, 253 feet above sea level
• Arch 5 – 330 feet above the ground, 332 feet above sea level
• Arch 6 – 250 feet above the ground, 252 feet above sea level

The four boom cranes also receive authorization to be installed, each at the height of 420 feet above the ground. They are planned to stay put until February 2021.

The bridge’s design will be unique, says the contractor Archer Western de Moya. The “Miami Fountain of Light” design as even a LED lighting system at night.

While the project completion is expected only for 2023, traffic relief should come much sooner, explained the contractors. That’s because, within 12 months of the start of construction, new lanes and ramps will start to enhance the flow of vehicles.
