WASHINGTON D.C. , January 7, 2016 – The newly built Amish Sawmill Bridge located at 1358 Dillon Avenue in Fairbank, Iowa will be dedicated with a ribbon-cutting ceremony featuring several government and transportation officials on Friday, January 8, 2016 at 11:00 a.m. The bridge is the first in the U.S. to be designed with the new press brake-formed tub girder technology, which is constructed with full-width steel plate that has been cold-formed using a press brake and supported by geosynthetic reinforced soil (GRS).
The ribbon-cutting ceremony will be followed by a reception at the Buchanan County Maintenance Shop at 831 Douglas Street in Jesup, Iowa. The reception will include remarks by:
- Ellen Gaffney, Buchanan County Supervisor
- Krista Taylor, Vice President, Taylor Construction Inc.
- Kevin Irving, Central Sales and Marketing Manager, AZZ Galvanizing
- David Stoddard, Chairman, Short Span Steel Bridge Alliance and Applications Engineer, SSAB Americas, Muscatine, Iowa
- Bob Hahn, Regional Sales Manager, U.S. Bridge
- Chris Cromwell, Bridge Engineer, Federal Highway Administration (FHWA)
- State Representative Bruce Bearinger (D) from Iowa
- Robert Wills, Vice President of Construction Market, Steel Market Development Institute, a business unit of the American Iron and Steel Institute
Buchanan County Engineer Brian P. Keierleber, P.E., oversaw all aspects of the construction and installation of the new bridge. The design was a collaborative effort between the Short Span Steel Bridge Alliance, the Iowa Department of Transportation and Buchanan County. It was constructed by Taylor Construction Inc. of New Vienna, Iowa. The bridge was partially funded through the FHWA’s Innovative Bridge Research and Deployment (IBRD) program with the assistance of the Iowa Department of Transportation and the Iowa Highway Research Board.
The press brake-formed tub girder technology was developed through the efforts of members of the Short Span Steel Bridge Alliance, led through the research efforts of Dr. Karl Barth (West Virginia University), Dr. Michael Barker (University of Wyoming), and Dr. Greg Michaelson (Marshall University). Its advantages include:
- A steel solution for new and replacement bridges with modular/prefabricated components that are economical and help accelerate construction.
- A reduction in additional details such as stiffeners and cross frames.
- The ability to be used for both tangent and skewed configurations on simple or continuous spans.
County engineers in other states have expressed interest in using this technology for their new and replacement bridge construction needs.
