Will it float? Wis. builds bridge on Web

When the Wisconsin Transportation Department floated a 2.8-million-pound steel arch down the Mississippi River and hoisted it on top of the Cass Street Bridge, they wanted to be sure nobody missed it.

The department webcast the Dec. 17 event at (click to link) using Mediasite Live Web communication tools from Sonic Foundry Inc. of Madison, Wis.

The webcast, available on demand, has more than five hours of video of the bridge installation as well as engineering diagrams, Microsoft PowerPoint presentations, and live interviews with engineers, project managers and elected officials.

Engineers from the Wisconsin DOT, Lunda Construction of Black River Falls, Wis., and other project team members floated the arch on barges and connected it to permanent bridge piers.

When completed, the new bridge will be 2,573 feet long and have four lanes, a bike path and a sidewalk. The bridge is one of two that span the Mississippi River at La Crosse, Wis. Officials said it will ease traffic congestion and improve the area's economic vitality.

Wisconsin DOT spent $40 million on the bridge, 80 percent from federal grants.
