Building a Bridge Across the St. Croix River in under Three Minutes

Although the project is a year behind schedule, this time lapse video of the 3,200-foot bridge over the St. Croix River can be watched in 2.24 minutes.  The project includes placement of pre-cast bridge segments and a truss scaffold section for the pier tables that can be lowered intact for disassembly.

The Minnesota Department of Transportation (MnDOT) has an excellent website with progress photos that explains the design and construction of the various components of the bridge that connects Minnesota and Wisconsin.  Click here to visit the MnDOT site.
