Input: Passage: The Downtown District is the home of the Third Street Promenade, a major outdoor pedestrian-only shopping district that stretches for three blocks between Wilshire Blvd. and Broadway (not the same Broadway in downtown and south Los Angeles). Third Street is closed to vehicles for those three blocks to allow people to stroll, congregate, shop and enjoy street performers. Santa Monica Place, featuring Bloomingdale's and Nordstrom in a three-level outdoor environment, is located at the south end of the Promenade. After a period of redevelopment, the mall reopened in the fall of 2010 as a modern shopping, entertainment and dining complex with more outdoor space.
Output:
How long is Wilshire Blvd.?
