The spider-like arches of downtown Miami’s Signature Bridge are now beginning to come out of the ground.
Contractors have begun vertical construction on the “legs” at the center pier where all six arches will eventually rise from, according to a new presentation from the Florida Department of Transportation. The first concrete pour of the legs is expected in late September or early October.
At the other end of the first arch, a concrete pour for a footing is expected within a few weeks, the presentation stated.
Once complete, contractors will begin installing precast segments of the arch bit by bit, supported by temporary towers that will hold the structure in place.
Only a small final segment of each arch will be cast in place.
Last month, a spokesperson for FDOT told The Next Miami that the precast segment installation was expected by late 2021 or early 2022 at the latest.
In total, there will be six arches built for the Signature Bridge, ranging in height from 180 to 330 feet above ground, and spanning 1,025 feet.

Each segment will be a precast installation, except for the final segment (seen in purple) poured in place. Temporary towers will support the structure during the work:
