Black Squirrel Creek Bridge, Parker truss bridge near Colorado Springs, United States

The Black Squirrel Creek Bridge is a steel truss bridge that crosses a creek using a skeletal frame design and concrete supports at each end. The structure displays the typical grid-like pattern characteristic of truss construction from that era.

The bridge was contracted to Charles B. Owen and A. S. Horner, with the truss built by the Minneapolis-Moline Power Implement Company; construction was complete in 1935. It carried U.S. 24 until a replacement project began in November 2011, traffic moved to a detour in January 2012, and the old span was dismantled. The new bridge, finished in August 2012 at about $3.5 million, incorporated the 1934 plaque from the original structure.

Locals called the 1935 truss the "green bridge" or "old green bridge" before its 2012 removal. The barred windows in its hollow concrete abutments gave rise to stories, of uncertain authenticity, that a chain gang or German prisoners of war were locked inside them.

The 1935 truss was dismantled in 2012 and replaced by a low-profile span on the same alignment; the original structure is no longer standing. The replacement incorporated the 1934 plaque from the old bridge, which can be seen on the new span. The site is on U.S. 24 in El Paso County, Colorado.

The concrete supports contain hollow chambers with barred windows that sparked local speculation about their original purpose. These unusual architectural features have made the bridge a subject of local stories and folklore over the decades.
