East Blithedale Rehabilitation Project

East Blithedale Project Banner

The April 21st Virtual Community Meeting Recording is available here.

Project Overview:

The City of Mill Valley recognizes East Blithedale Avenue as a vital corridor between downtown Mill Valley and Highway 101 as it serves as the northern gateway into the City’s residential, school and business areas.

The East Blithedale Avenue Rehabilitation Project is currently divided into 3 phases and the goal is to rehabilitate aging pavement conditions, install new bike lanes, upgrade existing traffic signals, and improve access. 

The project will interrupt the normal course of business and residential living in the projeast_blithedale_streetviewect area. The City is working to address key issues to minimize, where possible, construction-related impacts such as traffic congestion, noise, debris, parking, business operations, deliveries, and accessibility for residents, employees, and customers.

Project Update (February 2023)

Thank you for your continued patience as work continues to progress! East Blithedale Avenue is open to through traffic between Camino Alto and Downtown Mill Valley. Motorists may experience localized closures or flagged one-way traffic control until May 2023. Travel on Miller Avenue for easier access to Downtown Mill Valley.

Crews continue working on East Blithedale Avenue between Sunnyside Avenue and Amicita Avenue to make ongoing improvements. Roadway maintenance of East Blithedale Avenue will continue while Pacific Gas & Electric is working. We recommend motorists follow the posted speed limits and proceed with caution as East Blithedale Ave remains an active work zone.
