When the $646 million St. Croix Crossing Bridge project was finished in 2017, it replaced the Stillwater Bridge about a mile away and doubled the traffic capacity to four lanes. It is a mile long. On the Wisconsin riverbank, the platform is 150 feet above the water. About 14,000 trucks of concrete (140,000 cubic yards) were used during construction. The bridge’s design is called extradosed. This is a blend of box-girder and cable-stayed features.
