Las Vegas

Clark Avenue Railroad Underpass

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.

Historic Significance:
It is significant as the underpass allowed for access between Las Vegas and the settlements west of the city. Previously, it was a dangerous undertaking to cross the Union Pacific Railroad (ex-San Pedro, Los Angeles and Salt Lake Railroad) tracks.
