One-month road closure/detour begins May 7
Caltrans and its contractor Q&D Construction Inc. will be replacing the existing Lake Almanor Spillway bridge on Highway 89 due to severe deterioration and other deficiencies.
Preliminary construction work has already taken place without affecting traffic, but to demolish the existing bridge and construct a detour on the spillway while building the new structure, it is necessary to divert traffic onto Highway 147 for approximately one month. Caltrans asks drivers to note Highway 147 will be under one-way traffic control beginning April 30 through July 1.
Beginning Monday, May 7, traffic on Highway 89 coming from Canyon Dam and Greenville will be temporarily diverted onto Highway 147. Residents and visitors to Lake Almanor’s West Shore on Highway 89 will be allowed through up to 12 miles from the Highway 89/36 junction.
Motorists coming from Chester or Red Bluff on Highway 36 are advised to avoid Highway 89 and stay on Highway 36 to Highway 147.
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 in advance for their patience and understanding.
