Crane Offers 'Concrete' Advantage at St. Croix Crossing

摘要

The new St. Croix River Crossing bridge will be the fourth extradosed bridge in the country-a hybrid of concrete box girder and cable-stay design that minimizes environmental impact. It will replace the Stillwater vertical lift bridge, connecting cities in Minnesota and Wisconsin in a multiyear project to be completed in 2017. In 2015, contractor Lunda Construction partnered with Dawes in Wisconsin, a member of the ALL Family of Companies, for a crane to lift massive precast concrete segments for the bridge's driving surface. The 180-ton segments-each 48 ft wide, 18 ft tall and 10 ft deep-will arrive pnsite by barge.
