Expect traffic delays and detours around Hacienda Avenue in Campbell from now through Aug. 16.

Parts of the avenue and nearby streets will be closed to everyone except construction and emergency vehicles between 8 a.m. and 5 p.m. The Hacienda Avenue Green Street Improvement Project is scheduled for completion in September.

Residents will be allowed to use Hacienda Avenue from 5 p.m. to 8 a.m.

The Valley Transit Authority will temporarily provide alternate bus routes during the road closures. Garbage pick-ups will continue as scheduled.

The city is working with Los Gatos to coordinate detoured traffic to Winchester Boulevard, Knowles Drive, Pollard Road and Burrows Road. Closures will alternate between Burrows Road to Virginia Avenue and Virginia Avenue to Winchester Boulevard.

“Residents were notified a week before it started, and more than 700 notices went out,” said Fred Ho, the project’s manager.

He said 35 residents attended a June 1 community meeting on the project, but the city is continuing to reach out to residents on Hacienda Avenue.

According to city staff, parts of Hacienda Avenue have to be closed to ensure public safety and reduce costs. In addition, a large machine will be used to crush rocks so the pebbles can be used to fill the streets before asphalt is poured.

Ho said the contractor is working diligently to finish the project before school starts.

“It’s a good coincidence the contractor came up with this schedule,” Ho said. “We also did talk with the nearby school.”

Residents who need certain accommodations should contact Alan Hom, the city’s senior inspector, at 408.866.2168 or 408.425.4703, and Andrew Kellen, Ghilotti Construction’s project engineer, at 707.208.7688.

Updates on the projects and road closure will appear on the city’s website and message boards as information is added.
