Trunk Line Replacement on Coldwater Canyon Will Reduce Lanes Into Evening Hours Starting Thursday

Traffic impacts will continue as LADWP crews working to replace an aging trunkline along Coldwater Canyon move the major area of construction to a section of the roadway between Hacienda Drive and Avenida Del Sol.

Starting Nov. 15, construction hours will be extended from 9 a.m. to 8 p.m. Monday through Friday and 8 a.m. to 3:30 p.m. on Saturday.

Crews will work into the evening hours in an effort to expedite the replacement of the 100-year old trunk line in order to meet the timeline for completion for this portion of the project by March 2013.

Flaggers will be on site to coordinate traffic along this popular north-south route from Metro Los Angeles to the San Fernando Valley. Motorists are strongly urged to use alternate routes. LADWP has scheduled the lane reduction outside of heavy traffic hours.

Informational signage has been posted along Coldwater Canyon alerting drivers and area residents of this upcoming lane reduction. In addition, outreach has been done to inform area residents, local schools, and project stakeholders of the project's progress and construction impacts through monthly e-mails.

The construction along Coldwarer Canyon 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 and is required for compliance with federally-mandated water quality regulations. 

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 are of the city to another as needed.  Construction on CTLS-5 began in June 2011 and is expected to be completed in September 2015.

As construction progresses, and when conditions change, additional community updates will be provided.
