FINAL HEIGHT OF MIAMI’S ‘BRIDGE FOR THE AGES’ HAS BEEN APPROVED, & CRANES WILL NOW BE INSTALLED





Quote:
The final height for Miami’s Signature Bridge was approved by the Federal Aviation Administration this week.

Miami-Dade Mayor Carlos Gimenez has called the project “a bridge for the ages” in a 2017 memo.

A total of six arches are planned, with the tallest at 330 feet above ground:

Arch 1 – 180 feet above ground, 186 feet above sea level
Arch 2 – 230 feet above ground, 237 feet above sea level
Arch 3 – 180 feet above ground, 187 feet above sea level
Arch 4 – 250 feet above ground, 253 feet above sea level
Arch 5 – 330 feet above ground, 332 feet above sea level
Arch 6 – 250 feet above ground, 252 feet above sea level
All of the arches had their heights approved by the FAA last week, with review taking about ten months following a November 2018 application.

A total of four boom cranes were also approved for installation. Each crane will be installed this month at a height of 420 feet above ground, and will stay in place until February 2021.


[...]

Completion is expected in 2023, but contractors say that traffic relief for motorists will begin much earlier. Within 12 months of the start of construction, newly added lanes and ramps will already start to improve the flow of vehicles, they say.
