TRAFFIC ADVISORY: LADWP Water System Improvement Project to Reduce Coldwater Canyon to One Lane of Traffic

TRAFFIC ADVISORY:  LADWP Water System Improvement Project to Reduce Coldwater Canyon to One Lane of Traffic

Drivers are encouraged take alternate routes from December 19 – 30
LOS ANGELES — As part of construction on a major trunk line replacement project, LADWP crews will temporarily reduce Coldwater Canyon Avenue to one lane of traffic in an area just south of Ventura Boulevard, beginning on December 19 and lasting until approximately December 30. During the hours of 8:00 a.m. to 3:30 p.m., Monday through Friday, flaggers will be on-site to coordinate traffic along Coldwater Canyon Avenue, between Van Noord Avenue and Hacienda Drive, allowing one direction of traffic to pass at a time.  Each day, after work is completed, LADWP crews will restore Coldwater Canyon Avenue to two lanes of traffic with a single lane in each direction.

Drivers should expect significant delays due to the reduced traffic flow and are strongly encouraged to take alternate routes. In an effort to minimize traffic impacts, LADWP has scheduled the lane reduction to coincide with the reduced traffic flows during Harvard Westlake Upper School’s winter break schedule.

Informational signage has been posted along Coldwater Canyon Avenue for two weeks alerting drivers and area residents of this upcoming lane reduction. In addition, outreach has been done to inform area residents and project stakeholders of the project’s progress and construction impacts through monthly e-mail updates.

During this period of construction, Halkirk Street will remain closed to through traffic at Coldwater Canyon Avenue. Halkirk Street will be accessible to residents from Alcove Avenue, Goodland Avenue and Goodland Place. Harvard Westlake Upper School’s driveway on Coldwater Canyon Avenue will remain accessible to campus visitors during the winter break.

The construction along Coldwater Canyon Avenue is part of the City Trunk Line South – Unit 5 (CTLS-5) Project, which will replace an aging trunk line built in 1914. The new trunk line, consisting of 54-inch and 60-inch diameter pipe and approximately 1.3 miles in length, will improve the reliability and flexibility of LADWP’s water distribution system.

LADWP’s water system includes approximately 500 miles of trunk lines, which are large-diameter pipes that allow large amounts of water to be transported from one area of the city to another as needed. Construction on CTLS-5 began in June 2011 and is expected to be completed in May 2015.  Trunk lines are in addition to the over 7,000 miles of water mainline and other pipes that run under the city and provide water 24/7 to Los Angeles.
