Some Delays Expected as Safety Project Continues on Eastbound State Route 131, Trestle Glen Boulevard as Caltrans Relocates Traffic Pole

Published:

Marin County — Caltrans is scheduled to relocate a traffic pole as part of a safety project at State Route 131 (Tiburon Boulevard) and Trestle Glen Boulevard in April and May.

Map of State Route 131, Trestle Glen Boulevard where Caltrans Relocates Traffic Pole.

Crews will work to relocate the pole on Monday, April 28 and Tuesday, April 29 as well as Monday, May 5 and Tuesday, May 6 between 8 a.m. and 3 p.m. Traffic may need to stop intermittently on Eastbound SR-131 to allow equipment to get to the shoulder or material to be installed at the site.

This work is part of a bigger safety project that included a no right-turn-on-red sign at SR-131 and Trestle Glen Boulevard in February 2025.

The sign is a LED Blank-Out Sign. It only illuminates when a right turn is not allowed during a red signal for the Westbound Trestle Glen flow of traffic into the intersection.

All work depends on weather.

Motorists are encouraged to allow extra time and plan their routes ahead of time.
