Despite being a city street, the avenue between Junipero Serra Boulevard and Golden Gate Park is designated as part of the State Highway 1.

State Senator Leland Yee authored a bill designating 19th Avenue as a double-penalty zone for speeding, illegally overtaking, driving under the influence, driving recklessly, seat belt violations, and other traffic offences enforced by California Highway Patrol San Francisco Division, which took effect on 1 January 2009.
