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
, 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. Traffic through the tunnels is heavy at almost all times of Day
. At the north end of the tunnels is an interchange with Interstate 5 (Golden State Freeway), in which the leftmost lane makes a hard left turn onto the offramp. There are also sharp exit and entrance ramps on the right side at Solano Avenue
after the first tunnel.
Since the tunnels' incorporation into Arroyo Seco Parkway (now SR 110), Figueroa Street has been discontinuous. It merges into SR 110 at Alpine
Street in Chinatown, south of the tunnels, and splits in Highland
Park, north of the Figueroa Street Viaduct over the Los Angeles River
