when was the first freeway built in los angeles
Arroyo Seco Parkway The Arroyo Seco Parkway, formerly 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 It conformed to modern standards when it was built, but is now regarded as a narrow, outdated roadway.[4] A 1953 extension brought the south end to the Four Level Interchange in downtown Los Angeles and a connection with the rest of the freeway system.
Mitchell Freeway The Mitchell Freeway is planned to continue north to the Metropolitan Region Scheme's boundary, beyond Yanchep and Two Rocks.[45] The state government announced in March 2012 the formation of the Mitchell Freeway Extension Community Working Group.[46] The group worked with Main Roads Western Australia to investigate options for relieving congestion, with a focus on the next freeway extension.[47] Several options were considered,[48] before the group released a strategic business case in November 2012.[49] The report recommends a staged approach, starting with intersection improvements between 2013 and 2015. This was followed by a freeway extension to Hester Avenue in 2017. An expressway standard extension to Romeo Road, Alkimos is proposed to be completed by 2021.[49]
