MARIN COUNTY (KRON) — Highway 37 has been notorious for its constant closures during this winter’s storms.

This time around is no different.

Tuesday’s mighty downpour leaves the highway flooded and shut down once again.

California Highway Patrol says the overflow comes from Novato Creek.

Both directions of Hwy 37 are closed between Atherton Ave. and Hwy 101, according to the Novato Fire District, and California Highway Patrol.

Caltrans crews are currently on scene and attempting to pump water out of the roadway, California Highway Patrol officials said.

The highway, which has proven vulnerable to flooding, has already been closed twice for days at a time this year alone following heavy rain.

There is no estimation for reopening at this time.

Also in Marin County, Caltrans has closed state Highway 1 in both directions between the Panoramic Highway and Muir Woods Road. Caltrans officials estimated the highway wouldn’t reopen until March or early April.

In Sonoma County, state Highway 12 at state Highway 121 has been closed. No estimated time for when the highway would reopen was given by Caltrans officials.

Also in Sonoma County, one-way traffic control is in effect on Highway 1 four miles north of Jenner.
