Cultural Resource Survey, HAER Documentation, Historical Study, and Public Outreach, Gillespie Dam Bridge Project, MCDOT

From October 2005 to May 2006, ACS conducted a Class III cultural resource survey of over 445 acres at and surrounding the historic Gillespie Dam Bridge on old US 80. The project was conducted on behalf of the Maricopa Department of Transportation (MCDOT) through ACS’ on-call contract. This multidisciplinary project also included writing a historical context for the project area (Thomas Jones, ACS), completing a Historic American Engineering Record (HAER) for the bridge (Clay Fraser of Fraser Design, Colorado), and a public outreach list of opportunities for MCDOT to use for interpretative and recreational use of the area (Dr. Susan Shaffer Nahmias). Gillespie Dam Bridge is an 80-year-old nine-span steel truss bridge–one of the oldest such structures in the state–that is slated for rehabilitation by MCDOT. This venerable central Arizona landmark sits in a unique environmental and cultural location between Gila Bend and Arlington that has remained largely untouched by development since the 1920s. It has been deemed worthy of preservation by MCDOT for the benefit of current and future Arizonans and advance preparation for rehabilitation work is underway.
