St. Croix River Crossing Load Tests Move Forward
The Wisconsin and Minnesota Departments of Transportation recently provided a tour of the load tests currently being conducted in the St. Croix River south of the current Stillwater lift bridge.  The purpose of the load tests is to gather data for the design of the new bridge’s foundations. 
Drilled shafts are being installed over 100 feet beneath the water’s surface to reach sandstone that will serve as the base for the foundations.  The load testing will cost $3.5 million, but is expected to reduce project costs by $10-15 million.  To find out more about the load testing and the St. Croix River Crossing project, visit
