DOWNTOWN LOS ANGELES — Navigating Downtown can be tricky enough without running into an unexpected street closure. We'll try to help you out, posting notices from film shoots that include full street closures.

You have to admire Columbia Pictures' moxie in scheduling an exterior shoot for 'Bad Teacher' at City Hall on the day in which the LA Marathon brings 25,000 runners past two sides of the building. Still, perhaps with traffic already so disrupted citywide, one block of Spring just won't matter.

The shoot will have Spring street shut down between 1st and Temple from 5am on Sunday, March 21 to 5am on Monday, March 22.

The film stars Justin Timberlake, Cameron Diaz and Jason Segel.

DESCRIPTION OF SCENE: Driving scenes. Equipment on property, sidewalk, in curb lane & across street. Interior dialogue. Intermittent traffic and pedestrian control. Wetting down of the street. Extras holding in Board of Public Works Room, hanging banner in archway of forecourt, placing set dressing on property. 20 x 20 frames on the sidewalk. Class field trip scene. Generator. Picture vehicles. Scissor lifts.
