CALTRANS REACHES MAJOR MILESTONE IN ALTON INTERCHANGE PROJECT

SACRAMENTO – The California Department of Transportation (Caltrans) announced today that the Environmental Document for the preferred alternative for the Alton Interchange project was completed June 29, 2005. The preferred alternative is the Spread Diamond Interchange that will replace the existing at-grade intersection of Routes 101 and 36.

“We are pleased to announce that a major milestone in the development of this project has been met,” said Project Manager Richard Mullen. “This is a major regional project that will provide a safer highway facility and improve operations. Completing this milestone allows Caltrans to move forward into the Design phase when detailed plans and specifications will be developed for this preferred alternative.”

Reaching this milestone was a team effort and would not have been possible without the partnership and cooperation of the Humboldt County Association of Governments. Other key team members include: the City of Fortuna, Humboldt County Public Works Department, Humboldt County Community Development Department, California Highway Patrol, Department of Fish and Game, and the California Coastal Commission.

The construction cost of this project is currently estimated at $11,174,000 and will be funded through the State Transportation Improvement Program.

Construction is scheduled to begin in the summer of 2007 and it is anticipated the interchange will be open by spring 2009.
