Work Gets Underway in Iowa for Short Span Steel Demonstration Bridge Using eSPAN140

espan-button

An innovative, first-of-its-kind, bridge-building demonstration sponsored by the Short Span Steel Bridge Alliance is now underway in Buchanan County, Iowa. The design for the replacement bridge was created using eSPAN140, the free web-based design tool developed by the SSSBA to provide a more cost-effective manner to quickly design short span steel bridges. (See www.eSPAN140.com to learn more about the design tool). Click here to see the video from the live construction camera that was placed on the job site.

Old Buchanan County Short Span Bridge before Demoltion

This is the old bridge located outside Jesup, Iowa that is being replaced with a new short span steel bridge. This bridge was demolished August 20 by a Buchanan County Secondary Roads crew.

The bridge to be replaced is located on V-65 south of Jesup, Iowa.

The old bridge was demolished on August 20, 2013. Built in 1947, it had a sufficiency rating of less than 5 and was only 22 ft. wide. In its place will be a modern 40 ft. wide bridge with galvanized steel rolled-beams and galvanized rebar. The bridge construction and replacement is scheduled for completion in late October.

For old Bridges proper inspection and rehabilitation should be done. A proper bridge needs to be implanted so as for the feasibility of the people and safety as well. Soon the work gets done with a strong and life long bridge.
