The award recognized an article they authored to assist the Minnesota Department of Transportation with mitigation measures under Section 106 of the National Historic Preservation Act.

Under contract to MnDOT, Bob and Rick researched and authored an article on the history, development and widespread use of pre-stressed concrete within Minnesota. The article, Constructing Suburbia: The Hidden Role of Prestressed Concrete, was published in Minnesota History Magazine (Winter 2014-2015).

This is a great example of how historic preservation informs the public by mitigating adverse effects to historic properties, in this case Minnesota’s first prestressed concrete state highway bridge, completed in 1957. The award coincides with 50th anniversary of the National Historic Preservation Act, highlighting one of the many it provides public benefit.

The MNSAH bestows the David Stanley Gebhard Award to authors of outstanding articles and books that focus on a historical aspect of the Minnesota built environment. The award honors David Gebhard, the late Minnesota-born SAH president and nationally renowned writer.
