The famous one-block section, claimed to be "the crookedest street in the world", is located along the eastern segment in the Russian Hill neighborhood.

The design, first suggested by property owner Carl Henry[4] and built in 1922,[5] was intended to reduce the hill's natural 27 percent grade,[6] which was too steep for most vehicles.

[1] During peak times, vehicles have to wait up to 20 minutes to enter the Crooked Street segment, in a queue that can reach Van Ness Avenue.

[1] To reduce habitual congestion and delays, future visitors may be required to reserve a time and pay a fee to drive down the crooked street.

[11] Past residents of Lombard Street include Rowena Meeks Abdy,[12] an early California painter who worked in the style of Impressionism.
