For approximately a month and for 6 days a week – from 8:30 a.m. to 7 p.m.  Coldwater Canyon will be closed.

Coldwater Canyon – Uh oh, bad news bears if you need to use the canyon roads between Los Angeles and the San Fernando Valley.
Starting this weekend the L.A. Department of Water and Power (DWP), will be shutting down Coldwater Canyon to replace a 100-year-old water main.

Residents will be provided special passes allowing them access to and from their home. (What if they want to entertain guests, or have a party?)
Because of it being a high residential area with peeps living right along the roadside and due to the  loud construction noise, working overnight is not an option.

Coldwater Canyon will be closed from Ventura Boulevard to Mulholland Drive, from 8:30 a.m. to 7 p.m. Mondays through Fridays and 8:30 a.m. to 6 p.m. on Saturdays.

The closure begins this Saturday morning and is expected to last until April 26 – ish.

Overnight when construction is halted and on Sundays there will be one lane open in each direction.

Alternates –  If you drive between the Valley and Beverly Hills here are some alternates:
Cross over routes include Laurel Canyon Boulevard, Beverly Glen Boulevard, Sepulveda Boulevard, Cahuenga Boulevard/ Highland Avenue
and the I-405. Maybe you have a secret alternate that you can share with us?
The good news, no major closures are scheduled to take place on the 405 through the Sepulveda Pass at the same time as the Coldwater closing.

The Dailey News reports,
“This project is part of a major improvement project to upgrade the city’s water infrastructure. Due to the narrow road conditions of Coldwater Canyon Avenue and the need to use heavy equipment to excavate the road, remove and replace pipe, the thoroughfare must be completely closed to traffic to ensure the safety of the crew and the public.
“The route, one of several key ways into the Valley and the Los Angeles Basin, has some 1,300 cars per hour that will need to find alternative routes while the work is underway. “Coldwater Canyon Avenue is one of our key trans-mountain routes, and there’s no question its month-long closure will be a hardship to residents and commuters,” Los Angeles County Supervisor Zev Yaroslavsky said. “But the water trunk-line replacement work’s got to be done.”

Steps to mitigate traffic problems include electronic signage, traffic control officers and new striping of streets to guide motorists through the area.”

Why oh Why? Because of the narrow road conditions and the amount of heavy equipment needed to excavate the road, remove and replace the 60-inch pipe.
The shutdown of the street is necessary, officials from DWP said.
In 2009 while  Zach Behrens was in charge at LAist, the water main at Coldwater Canyon and Ventura Boulevard ruptured. The result was extensive flooding for the residents and businesses. Repairs costing more than $700,000 and claims of more than $8 million were filed against the city. In addition, it was estimated more than 4 million gallons of water spilled. Behrens took a picture.

The missing link? The City Trunk Line, known at the time as the “San Fernando Syphon,” an underground water pipe stretching from Sylmar across the Valley (not yet part Los Angeles) through a tunnel in the Santa Monica Mountains to the Franklin Reservoir above Beverly Hills.

With the trunk line’s completion on June 6, 1914, and connecting pipes finished the following year, Mulholland’s aqueduct at last had a direct connection to the city whose growth it would fuel so explosively in the decades to come.
