The Clark Avenue Railroad Underpass, also known as the Bonanza Underpass, is a bridge and underpass in Las Vegas, Nevada, United States that is listed on the National Register of Historic Places. The bridge is so named since at the time of construction it crossed Clark Avenue which was later renamed to Bonanza Road.[1] The underpass is currently part of Nevada State Route 579.
The bridge was constructed in 1937 by the Works Progress Administration.[1][4] The structure has changed over time, primarily due to a widening project on Bonanza Road.[1]
