The Figueroa Street Tunnels are a set of four four-lane tunnels that carry northbound traffic on State Route 110 (the Arroyo Seco Parkway) through Elysian Park in Los Angeles, California, United States. From south to north, the four tunnels measure 755, 461, 130, and 405 feet (230, 141, 40, and 123 m) in length, 46.5 feet (14 m) in width, and 28.3 ft (8.6 m) in height. The north three tunnels opened in 1931 as a bypass to a section of North Broadway; the southernmost (and longest) opened in 1935, connecting to Figueroa Street downtown. Connections were added in 1937 to the Figueroa Street Viaduct, 1940 to the Arroyo Seco Parkway (known until 2010 as the Pasadena Freeway), and 1953 to the Four Level Interchange.
