Residents of La Crosse, Wis., will be crossing the Mississippi River on a modern bridge in 2017, when the new twin post-tensioned concrete segmental bridges are completed. The existing bridge is fracture-critical in addition to having shoulders and approach geometry that are not up to modern standards. The new bridge is being constructed from above with form travelers in balanced cantilever using eco-conscious construction methods with a focus on minimizing disruption to wetlands and fishing holes of the nearby wildlife and fish refuge.
