Flooding Disrupts Major Mill Valley Routes As High Tides Return: Police

MILL VALLEY, CA — Tidal flooding has once again forced the closure of a busy Mill Valley roadway Thursday, with no estimated time for reopening, police said.

Miller Avenue was closed between Almonte Boulevard and Camino Alto, and Redwood Highway Frontage Road was closed at Hamilton Drive due to tidal flooding, authorities said around 1 p.m. on Thursday.

Police did not provide an estimated reopening time.

Drivers should avoid the closed section of Miller Avenue and use alternate routes until the roadway reopens, police said.

The closure follows a series of similar incidents in recent weeks.

On Nov. 9, tidal flooding closed both Miller Avenue and Redwood Highway Frontage Road. The same roads were repeatedly affected in late October, when unusually high tides caused flooding across southern Marin County.

The National Weather Service has warned that elevated water levels can flood low-lying coastal roads, with additional high tides expected around Thanksgiving and Christmas.
