SIGNATURE BRIDGE DECK CONCRETE POURS COMPLETED
Construction continues on the westbound Signature Bridge superstructure with the successful completion of another concrete deck pour. Once complete, this section of the bridge will be suspended above NE 2 Avenue and Biscayne Boulevard, supported by the bridge’s iconic arches and suspension cables.
In addition to the deck, crews previously placed concrete for the web walls and diaphragms, key structural components that provide strength and stability to the bridge superstructure.
The operation required approximately 530 cubic yards of concrete for the deck, delivered by 55 concrete trucks and placed using two concrete pump trucks. An additional 390 cubic yards of concrete were placed for the web walls and diaphragms, bringing the total concrete placed during these two operations to approximately 920 cubic yards.
Photos below highlight this phase of construction.
