Spillway detour to open May 24

Caltrans announced today that the spillway detour near Lake Almanor will open May 24.

The California Department of Transportation and its contractor Q&D Construction Inc. continue building a new Lake Almanor spillway bridge on Highway 89 in Plumas County, with the old bridge scheduled to be demolished by Memorial Day weekend.

A new, temporary detour adjacent to the project has been built and is projected to open May 24. Motorists will be able to drive through on Highway 89 to the Lake Almanor West Shore and/or the Highway 89/Highway 36 junction.

Drivers can expect one-way traffic control with a signal on Highway 89. The speed limit on the detour is 25 mph, so slow down. Anticipate delays up to seven minutes.

The new, temporary detour is for all vehicles including bicycles. Large, heavy trucks must follow rules for California rural highways.

The $9 million project is slated for completion by mid-November 2018. Construction may occur on weekends. Night work is not anticipated.

Caltrans thanks the public for their cooperation. For more information, call 225-3426 during business hours.

    I’ve read the existing spillway would not hold up if actually used. (ex. Oroville Dam spillway) What good is a new bridge if the spillway itself is inadequate as I understand it is currently.
