Caltrans has completed a Final Environmental Impact Statement and a Final Environmental Impact Report for the Eureka-Arcata Corridor Improvement Project. These documents can be found here. Caltrans is planning on certifying these documents and approving this project in January 2017. Permits will then need to be obtained and a final design will need to be approved.
Caltrans and the Federal Highways Administration (FHWA) are proposing safety and operational improvements on U.S. Highway 101 between Eureka and Arcata in Humboldt County, including a grade separated interchange at Indianola Road, a half signal at Airport Road, and a bridge replacement. The primary purpose of the proposed project is to improve safety at uncontrolled left turns on and off the highway.
