110 Freeway N. Figueroa Street Tunnels 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. A new alignment for southbound traffic, passing through a cut to the west of the tunnels, opened in 1943.
