Flooding Forces More Road Closures As Problems Persist In Mill Valley

MILL VALLEY, CA — Flooding forced the closure of two busy Mill Valley roads again Friday, continuing a weeks-long pattern of disruptions that has repeatedly sent drivers searching for alternate routes.

The Mill Valley Police Department issued an advisory at 12:01 p.m. Friday, warning motorists to avoid the following areas:

• Miller Avenue between Camino Alto and Almonte Boulevard.
• The west side of Redwood Highway Frontage Road between Hamilton Drive and the southbound Highway 101 off- and on-ramp.

Both roads will remain closed until floodwaters recede, police said. Drivers should follow detours and avoid the affected areas.

The latest closures come just one day after tidal flooding shut down the same roads Thursday.

The recurring flooding has become a persistent problem for motorists in southern Marin County.

On Nov. 9, both roads were closed due to tidal flooding, following a series of similar closures in late October.

During the last week of October, flooding repeatedly disrupted roads across Mill Valley, Larkspur and Corte Madera, as exceptionally high tides pushed water into low-lying coastal areas.

On Oct. 26, both Mill Valley roads reopened after floodwaters receded, only to close again the following day.

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. The extent of future flooding will depend on ocean conditions and whether high tides coincide with storms or large waves.

Police urged drivers to avoid the flooded roadways and use alternate routes until conditions improve.
