Eureka – Caltrans today celebrated the opening of the new Roger M. Rodoni Memorial Interchange at the junction of State Route 36 and U.S. Route 101 in Alton. The $14.5 million project was completed one year ahead of schedule and was entirely funded by Proposition 1B, a $19.9 billion transportation bond championed by Governor Arnold Schwarzenegger and approved by voters in 2006.

The new interchange was named in honor of former Humboldt County Supervisor Roger M. Rodoni, a strong supporter of transportation improvements in the North Coast for many years. Mr. Rodoni, who was born in Scotia in 1940, passed away in 2008. The new interchange will help reduce collisions, make it easier for vehicles to merge, and reduce waiting time for turning. The interchange combines ramps, local road extensions, and a grade separation to provide a transportation facility constructed to current standards.  

Caltrans, the Humboldt County Association of Governments, and the Federal Highway Administration worked together to plan the interchange near the communities of Fortuna, Rio Dell, and Hydesville.

"Caltrans is proud of this interchange project, which will make the roadway safer for North Coast residents and visitors alike. We also appreciate this opportunity to recognize Supervisor Roger Rodoni for his professional and personal achievements,” said Caltrans Director Cindy McKim. 

To date, nearly $6 billion in Proposition 1B funding has been allocated by the California Transportation Commission and Caltrans.
