Caltrans press release:

Caltrans maintenance crews will be trimming eucalyptus trees from June 1 to roughly June 18 along the U.S. Highway 101 safety corridor. During this time, Caltrans is advising cyclists traveling southbound from Arcata to Eureka to utilize Route 255 as an alternative. This work is a safety precaution to reduce the chance of limbs falling onto the roadway and shoulder.

Cyclists will still be able to travel northbound on the corridor from Eureka to Arcata.

Work hours will be 9 AM to 4 PM Monday through Thursday. Southbound traffic will be reduced to one lane and motorists should expect minor slowdowns.

The completion date depends on the weather and the amount of trimming necessary for the effort. The public can “like” Caltrans District 1 on Facebook for updates at
