Westbound Chanate Road Traffic Detour April 26 – April 30, 2021

A traffic detour is scheduled for westbound traffic on Chanate Road, between Belvedere Way and Mendocino Avenue, to be in effect from Monday April 26 through Friday, April 30 from 7:30 am to 5:30 pm. The detour will allow for the excavation and installation of a large sewer pipeline under Chanate Road (schedule subject to change due to weather or unforeseen circumstances). Travel in the eastbound direction will remain open.

Westbound traffic on Chanate Road will be detoured south onto Humboldt Street continuing to Franklin Avenue, then west onto Lewis Road, to reach Mendocino Avenue (see map below). Local traffic entering Chanate Road between Belvedere Way and Mendocino Avenue from side streets and residences will be directed to turn in the eastbound direction on Chanate Road. Please avoid this area, if possible, during the detour, and observe all traffic control signs and measures. Do not enter areas that are coned or fenced off.

Single Lane Traffic Control on Upper Chanate Road from May 3 – May 7, 2021

Single lane traffic control will be implemented on Chanate Road from Humboldt Street to approximately 2755 Chanate Road (about 200 feet west of Terra Linda Drive), to allow for sewer line installation. This traffic control will be in place from Monday, May 3 through Friday, May 7 from 7:30 am to 5:30 pm. After those hours both lanes of the roadway will be open to traffic.

Flaggers will be stationed on-site to coordinate the safe movement of each direction of traffic through the traffic control area. Please be aware of all signage, follow direction of flaggers, and use extra caution. Expect traffic delays – consider an alternate route if possible.

Water and Sewer Line Work Continuing on Lower Chanate Road – April 19 – April 23, 2021

Team Ghilotti will be working on water and sewer lines on Chanate Road from Mendocino Avenue to Lomitas Avenue through April 23. This work is weather dependent. You may see No Parking signs on Chanate Road. These temporary parking restrictions allow the contractor access to perform work on sewer lines within the parking areas. Hours posted are between 7:30 am – 5:30 pm Monday–Friday. These signs are temporary and will be removed once activity is complete. Please drive with care and caution through the construction areas.
