As the the Department of Water and Power faces a second water main break of the week—this latest one sucked in a fire truck—the first one from Saturday night continues to leave Coldwater Canyon Boulevard closed to rush hour commuters as they return from the holiday weekend. The popular over-the-hill cut through to Beverly Hills is closed between Ventura Boulevard and Halkirk Street and between Moorpark and Ventura Boulevard (see a map below).

Officials last night said they could not estimate when work would be completed, but the street is expected to closed through at least today.

Additionally, inspectors yesterday found that a portion of the bridge over the L.A. River may have been destabilized. Authorities recommend avoiding trying to use Coldwater Canyon between Ventura Boulevard and Mulholland Drive.
