Cracked Ferndale Bridge
The California Highway Patrol (CHP) and local police responded to a bridge in Ferndale, California, where the earthquake on Tuesday morning caused cracks in the structure.
The bridge is the connection to Ferndale, population 1,387: “State Route 211 in Fernbridge, Humboldt County is CLOSED. The bridge is closed while we conduct safety inspections due to potential seismic damage,” Caltrans District 1 tweeted.
According to the CHP incident information page, the bridge cracked in four places, there is debris on the road, and law enforcement is on scene to facilitate the road closure.
According to the Humboldt County Sheriff’s Office, if the crack in the bridge “gets bigger,” the roadway could slip, the CHP said.
California State Senator Mike McGuire, representing the quake-hit area, tweeted about the bridge’s closure, assuring residents that “CalTrans will remain on site to assess the structure,” his tweet said.
