170th Anniversary of the First Cast Iron Bridge in the United States.

Hi everyone,

Here is a newspaper article about the first cast iron bridge in the United States. Located in Brownsville PA, the Dunlap Creek Bridge is a marvel of early 19th century architecture. I was interviewed by the Observer Reporter newspaper out of Washington, PA. Read about its history, and examine the photograph attached to this posting! I will be a guest expert speaker at the celebration occurring July 4th, 2009 so if you're in the Brownsville/Pittsburgh area, stop by and enjoy the celebration!
