This drone video offers an aerial view of ongoing construction on the I-395 Signature Bridge. Arches 1, 2, 4, and 5 are closed, while crews continue work on the first of three cast-in-place structural elements for each of the two remaining arches, 3 and 6. Other work shown includes the installation of falsework, formwork, and reinforcing steel, along with concrete pours for the westbound Signature Bridge superstructure, which will ultimately be supported by the arches and stay cables.
