County of Humboldt press release:

Heavy equipment will be used early on Sunday morning to install two new air handler units on top of the Humboldt County Courthouse and the public is advised to stay out of the area until construction is complete, expected to be later in the day.

The air handler installation is part of a larger project to remodel the fifth floor of the building and move the District Attorney-Victim Witness Program to the top floor.

The courthouse is scheduled to be vacated by 6:30 a.m. and movement of heavy equipment will begin shortly thereafter. Streets around the courthouse will be blocked until roughly 8 a.m. California Highway Patrol will block 4th and 5th streets, and Humboldt County Public Works will barricade 3rd and 6th Street, and I Street.

The public is advised to stay out of the area until construction is complete to ensure proper social distancing in light of the COVID-19 pandemic.
