The entire connector, completed in 1993, is 2.2 miles (3.5 km) long and includes seven bridges. [2] [8]

The Arroyo Seco Parkway, also known as the Pasadena Freeway, is the first freeway in the Western United States. It connects Los Angeles with Pasadena alongside the Arroyo Seco seasonal river. It is notable not only for being the first, mostly opened in 1940, but for representing the transitional phase between early parkways and modern freeways. It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway. A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system.

The north three tunnels opened in 1931 as a bypass to a section of North Broadway; the southernmost opened in 1935, connecting to Figueroa Street downtown. In 1937, a viaduct, known as the Figueroa Street Viaduct, was constructed to the north of the tunnels, dedicating the tunnels to 4 lanes of eastward traffic and the viaduct to 4 lanes of westward traffic once the viaduct was opened in 1943. Ever since the opening of the tunnels, connections have been added to the street, most notably in 1940 to the Arroyo Seco Parkway and in 1953 to the Four Level Interchange.
