The I-74 Mississippi River Bridge officially opened for eastbound traffic yesterday with a ribbon-cutting ceremony.
The new bridge features dual basket-handle arches with main channel spans of 800' and includes a multi-use path along the downstream of the bridge. Aldridge’s scope of work included streetlights, LED architectural fixtures, miles of suspended conduit under the bridge for future expansion, a network of power necessary to ventilate and illuminate the arches, and electronic sensor equipment to constantly monitor the structural health of the bridge. Aldridge planned and executed an innovative approach to the work by installing conduit within the arches prior to delivery on-site. Leveraging prefabrication in an off-site location helped streamline efficiencies and provided a safer work environment by decreasing work time spent over the river.
