Construction continues to advance on the westbound I-395 Signature Bridge superstructure, with crews installing reinforcing steel, formwork, and post-tensioning ducts and placing concrete for the massive box-girder deck. The post-tensioning system will add strength as the deck is constructed and work with the bridge’s arches and stay cables to support the completed superstructure. Recent concrete operations have included pours for the deck, webs, and diaphragms that make up the box girder. The video shows one of the largest concrete pumps in the country in action during a recent pour on the westbound Signature Bridge superstructure. As work progresses, these sections are coming together to form the new westbound I-395 roadway.
