Zion-Mount Carmel Highway, Co-op Creek Bridge, Spanning Co-op Creek, Springdale, Washington County, UT

Significance: The Co-op Creek Bridge was constructed by the Bureau of Public Roads as part of the Zion-Mt. Carmel Highway. The development of the Zion-Mt. Carmel Highway is significant to the development of the National Parks in Utah and Arizona. Access to the four parks in this area, Bryce Canyon, Grand Canyon, Cedar Breaks, and Zion National Park was greatly improved with the building of the highway. Each component of the highway system is important as it relates to the development of this area and tourism as a major industry in Utah and Arizona. Due to the rugged terrain in Zion National Park, each bridge and tunnel was integral to the highway's completion.
