The Marin County Department of Public Works will hold an online public meeting later this month to review proposed design improvements for a heavily used intersection on Mount Tamalpais known as Four Corners.
At the virtual meeting on Oct. 30 at 6 p.m., county officials will provide a progress update on the short-term design and discuss the proposed changes to the intersection layout and signage modifications to improve traffic circulation and safety.
Since a prior public meeting in December 2022, a design team has been working on a detailed short-term solution including lane realignment and signage plan, which is targeting construction for 2024.
The intersection of Panoramic Highway, Sequoia Valley Road and Muir Woods Road provides access between U.S. Highway 101, Shoreline Highway, Mill Valley and Tam Valley to Muir Woods, Mount Tamalpais, Stinson Beach and other West Marin destinations frequented by locals and visitors alike.

The Four Corners intersection typically has a daily traffic volume of around 4,100 vehicles on weekdays. That number can swell to over 7,000 vehicles per day on weekends with nice weather, county public works officials said.
The Four Corners project aims to improve visibility and functionality for all users, including tourists who may need to become more familiar with the area. The project will improve the configuration of the intersection, including skewed approaches of the roadways and lane alignments.
Initial analysis of the intersection led to two design concepts, which were presented at the December 2022 meeting. The short-term concept was to redesign the existing lane layout approaching and through the intersection, which could be accomplished by repainting lane lines and improving signage.
The long-term alternative would replace the intersection with a roundabout. In addition to needing funding for construction, implementation of a roundabout would involve extensive engineering and design work, community outreach, and coordination with surrounding landowners, the Marin County Department of Public Works said.
