Eureka-Arcata U.S. 101 Corridor Improvement
Caltrans has been making improvements to U.S. 101 between Eureka and Arcata. These safety and operational improvements include an undercrossing at Indianola Road, a northbound traffic signal at Airport Road, acceleration and deceleration lane improvements, the installation of cable median barrier, bridge and rail replacements at Jacoby Creek and Gannon Slough, and tide gate replacements.
This undercrossing project at Indianola Cutoff is intended to enhance safety. Caltrans does not anticipate significant traffic impacts for this project, but travelers are advised to remain alert and slow for the cone zone as traffic conditions can change quickly.
While subject to change with conditions, this project is currently estimated to be complete by the end of 2025.
