Cherry Creek Bridge, Concrete arch bridge in Franktown, Colorado.

Cherry Creek Bridge carries State Highway 83 over Cherry Creek near Franktown, Colorado, inside Castlewood Canyon State Park. The 1948 concrete arch structure was designed and built by the Colorado Department of Highways with J.H. & N.M. Monaghan & Associates, and it is listed on the National Register of Historic Places.

The structure was built after World War II and represents the concrete construction methods developed during that era in Colorado. Its recognition as a historic place came decades later, marking its importance in the region's engineering history.

The bridge represents post-war engineering practices in Colorado, departing from the standard lighter concrete designs common during that period.

The bridge can be seen from the main highway passing through the area, making it easy to observe during a drive through the valley. Best viewing comes from crossing it directly or from nearby park access points along the route.

The bridge carries State Highway 83 over Cherry Creek inside Castlewood Canyon State Park, so drivers cross it without noticing. Its 1948 design by the Colorado Department of Highways and J.H. & N.M.
