Help plan the future of SR 37!

Caltrans, the Metropolitan Transportation Commission
and transportation agencies for Marin, Napa, Solano and Sonoma counties are seeking your input on the Future of Highway 37. These agencies will be participating in an upcoming online public Townhall meeting hosted by Senators McGuire and Dodd.

At this meeting the agencies will discuss three coordinated planning efforts to develop solutions for improving SR 37. These planning efforts include:

• An Ultimate Resilient Sea Level Rise Design Alternatives Assessment focused on Highway 37 within Marin and Sonoma counties between U.S. 101 and Highway 121
• A Comprehensive Multimodal Corridor Plan to identify goals, corridor needs and challenges, and project priorities for various modes of travel to inform decision-making and future funding.
• A corridor-wide effort known as the Planning and Environmental Linkage to identify and narrow the range of alternatives to be advanced for environmental review and construction
The public is invited to attend this Townhall to learn more and find out how to become involved in the planning for the future of this critical transportation corridor.

Please review the attached flyer to learn how to become involved and make your ideas heard!

UPDATE in : Police cars revolving lightState Route 160 CLOSED Construction sign @ West Sherman Island Rd. due to traffic collision. Expect delays. Caltrans District 4 CHP - South Sacramento
* * * HIGH VISUAL HORIZON * * *

What is it? It's something we should all practice from the time get our driving permit...something that could save your life.

But what does it mean? It means to look way ahead while driving rather than directly in front of your vehicle. By maintaining a "High Visual Horizon" you could avoid being involved in a traffic collision since you'll be able to see vehicles' break lights up ahead and traffic slowing down way before you get there. It will give you time to gradually slow down allowing vehicles behind you to also slow down gradually and therefore avoid crashing into your vehicle.

So...have you ever wondered why Caltrans has these yellow crash pads on their trucks? This crash happened on SR-92. The driver of this vehicle failed to change lanes in time and avoid the closure up ahead causing their vehicle to collide with the attenuator truck.

These trucks are placed inside a closure protecting workers that are typically walking on the road within the closure and separated from fast moving traffic only by orange traffic cones. Without this truck in place, this vehicle could have possibly ran over a worker inside the closure. Which is why we urge you to and pay attention.

As you make your way out of town for the holiday, don't leave in a hurry, use a rest area if tired and simply enjoy the drive.
