1940: A geological report concerning the North Figueroa corridor in advance of the proposed “Southerly Extension” of the Arroyo Seco Parkway.
The recently opened Parkway terminates at Avenue 22, attracting “so large a volume of traffic…that the adjoining sections of this highway which have not already been adequately improved become badly overtaxed.”
Recommendations are made to use the four existing tunnels, roadway and bridge over the Los Angeles River between Castelar Street and Avenue 22 for northbound traffic only. Additionally, a four-lane bridge is proposed above Riverside Drive, as well as a four-lane roadway to complete the Arroyo Seco Parkway’s connection to downtown.
