The St. Croix Crossing 4 lane bridge project connects Oak Park Heights, MN and St. Joseph, WI. The extradosed bridge system, a hybrid combining concrete box girder and cable-stayed bridge designs, is only the second extradosed bridge constructed in the United States. This major project will reduce severe traffic congestion by diverting traffic from the historical Stillwater Lift Bridge constructed in 1931 to a four-lane bridge that will connect expressways on both sides of the St. Croix River. At over 5000 feet in length, the bridge consists of approx. 60,000 cubic yards of concrete for the 650 precast main bridge girder segments. In total there are approximately 1000 precast concrete segments.
