Background

Fernbridge is a concrete arch bridge on Highway 211 in Humboldt County, California. The bridge crosses the Eel River and is a beloved local landmark. Engineers built Fernbridge in 1911 and named it the “Queen of Bridges” due to its size. Fernbridge is the longest working poured concrete bridge in the world. It is on the National Register of Historic Places.  

The City of Ferndale depends on Fernbridge for direct access into town. Dairy, ranching, and tourism form the basis of Ferndale’s economy. The only alternate route is a time-consuming detour along Blue Slide Road.  

On December 20, 2022, there was a 6.4 magnitude earthquake 8 miles west/southwest of Ferndale. The earthquake caused widespread damage throughout Humboldt County. Fernbridge sustained major damage and closures. A second earthquake occurred on January 1, 2023. The earthquake increased pressure on the bridge. It highlighted the need for the Ferndale Access project. Caltrans completed safety repairs to allow two-way traffic by March 2023.   

Caltrans has scheduled one final element of emergency repairs. It will install a seismic gate system. If an earthquake occurs, the system will automatically close Fernbridge. The closure will prevent travel across the bridge. Caltrans will then complete a safety inspection before reopening to the public.  

Purpose

The purpose of this project is to restore reliable access to and from the city of Ferndale for all roadway users, which includes providing a structurally resilient bridge that meets current bridge design standards, reducing risk of damage from future events. 

Need

Fernbridge is the main route to and from Ferndale. On December 20, 2022, a 6.4 magnitude earthquake hit near Ferndale, damaging the bridge and road. Sensors showed shifts in the bridge's structure and widening cracks. Emergency repairs followed, aiming to reopen traffic and limit damage. However, a permanent fix is essential to strengthen the bridge against future earthquakes.

Benefits

Ferndale's economy depends on dairy, ranching, and tourism. Drivers must use Blue Slide Road for detours, which is long, time-consuming, and not suitable for increase in traffic. A safe, efficient route is vital. Fernbridge updates help the economy, residents, and tourists. It also ensures that emergency responders and goods and service providers have access to Ferndale.
