Miller Avenue road reconstruction work is on schedule and moving at a strong pace. The next few weeks of the project will include paving work in every section of the roadway, from Sunnyside to Almonte.
The majority of the road reconstruction and paving work will occur this summer so you can expect to see a new, smooth uniform surface on Miller Avenue soon.
Thank you for your continued patience during construction.

Paving continues in the Passage, Parkway, Gateway and Marsh. The City is using an innovative pavement recycling approach called “Cold In-place Recycling” (CIR). CIR-FA is considered the most environmental-friendly and cost-effective method among the various in-place pavement recycling techniques. In the CIR process, a portion of the existing asphalt is milled off, and the reclaimed material is mixed with foamed asphalt and cement then spread and compacted to produce a base layer for the final new pavement. The environmental benefits of CIR over traditional paving includes an estimated 62% savings in aggregate consumption, and a net savings in gas emissions, including 52% less carbon dioxide, 54% less nitric oxide/nitrogen dioxide, and 61% less sulfur dioxide.
Benefits of CIR Technology:
The use of CIR technology in pavement rehabilitation and reconstruction has been on the rise in the last two decades because it offers many advantages that include:

City Council Receives Report - Supports Work Plan
At their City Council meeting on Monday night the City Council received a report and presentation regarding the upcoming paving work on Miller Avenue, slated to begin in mid-June and early July. Repaving of the roadway is anticipated to cause disruptions and impacts to the community in regards to traffic congestion, limited vehicle access, detours and noise. As such, the project team is working to minimize impacts on residents, businesses, and commuters. One key recommendation is to conduct the paving work at night.
The City Council received an informational presentation and discussed the proposed work plan. Along with their general support of the paving work plan, Councilmembers encouraged staff to continue to outreach to the residents and businesses on Miller Avenue to inform them of the next phase of the project and anticipated schedule.
Description of Upcoming Paving Work
The roadway in the Passage, Parkway, and Gateway will receive a paving treatment that involves only the top asphalt layers, called Cold In-place Recycling (CIR). Following the completion of the two processes, the entire street will be paved with a 2 inch final layer of asphalt to provide a uniform surface.
The Main Street area (from Willow to Reed and Valley Circle) involves a more detailed paving process, known as “Full Depth Reclamation” (FDR). Basically, FDR pulverizes up to 18 inches of the underlying roadway, reuses existing ground materials and then overlays with new asphalt. FDR is 50% less expensive than traditional road repair methods, reducing excavation as well as the import and export of materials. The final road will be uniform, have a consistent cross slope, and offer a 20-year design life with regular maintenance. This section of roadway requires such a detailed paving process in order to address elevation changes to improve safety and overcome difficult soil conditions.
Paving Work Plan
Paving will occur on one side of the median at a time (inbound and then outbound), requiring traffic detours around paving work. The project team proposes to safely construct the roadway as quickly as possible to minimize impacts to the community. To accomplish this, FDR repaving work is recommended to take place at night, cutting the work time by 2-3 weeks, minimizing disruption to the community and businesses, and maximizing driveway access. Nighttime paving work is anticipated to take 3-4 weeks to complete. If the paving project is limited to daytime work only, it will take approximately 5-7 weeks.
The City will begin paving work this summer, when school is out and traffic is generally lower in Mill Valley. The proposed night work hours for the FDR paving in Main Street are from 7 pm to 9 am, with the work week beginning Sunday night at 7 pm and extend to Friday morning at 9 am. Other construction work, such as sidewalk repairs and possibly roadway paving in other areas of Miller Avenue will continue on Miller Avenue from 7 am to 7 pm, Monday through Friday. The FDR paving process will create noise mainly generated by the sound of the equipment's engine and milling teeth as they pulverize the asphalt.
