📍 Help Shape the Future of Point Reyes Station

The Marin County Department of Public Works is kicking off a Transportation Planning study — and we want to hear from you!

Join us for a community workshop to share your thoughts on parking, walking and biking circulation, wayfinding, and the overall look and feel of potential improvements in Point Reyes Station.

We’ll share a brief presentation and examples of potential design concepts, followed by an interactive activity to hear what works, what doesn’t, and what you’d like to see considered.

📅 Monday, October 26
⏰ 6–8 PM
📍 West Marin School – Small Gym
11550 Shoreline Hwy, Point Reyes Station

This is the first phase of the study, and community input will help identify needs, opportunities, and design preferences as concepts are developed.

Come share your ideas and help shape what comes next!

HAWK Signals: Know Before You Go

Have you used the HAWK signal at Sir Francis Drake and Ash Avenue? Whether you’re driving, walking or biking, understanding how the HAWK works helps everyone cross safely.

The HAWK signal is different from a traditional traffic light. It stays dark until activated by a pedestrian and then uses a series of yellow and red signals to stop traffic for the crossing.

One important reminder: Drivers should not stop for people waiting to cross when they have the right of way. While stopping may feel courteous, it can create confusion if a pedestrian sees one vehicle stop while traffic in another lane is still moving.

🚗 Drivers: Follow the HAWK signal and avoid unexpected stops when you have the right-of-way.

🚶 Pedestrians: Wait for the walk signal before entering each portion of the roadway.

A predictable crossing is a safer crossing. Knowing the signal and following the signal helps keep everyone moving safely.

The Mill Valley–Sausalito Multi-Use Pathway just north of the McGlashan Path intersection is currently under construction. The path remains open; however, travel across the bridges is currently limited to a single lane. The narrowed crossing is designed to safely accommodate two-way pedestrian traffic and cyclists walking their bikes, with ample room for both.

Cyclists using the path this weekend must dismount and walk their bikes across the bridges while passing through the work zone. With the long holiday weekend expected to bring heavier-than-usual trail traffic, we ask everyone to slow down, follow posted directions, and be courteous to fellow path users.

To help keep everyone safe and traffic moving smoothly, Marin County Sheriff's deputies will be on site this weekend to observe conditions, assist with traffic flow, and help ensure the work zone remains safe for all users.

Thank you for your patience, attention, and cooperation as crews complete this work safely.
