West Portal Soundwall Painting Completed

Caltrans has completed painting the temporary soundwall at the west portal of the tunnel. Workers began planting 77 fast growing evergreen Leyland Cypress trees between the soundwall and the curb. Near the conclusion of the project in late 2013 or early 2014, the soundwall will be demolished and the trees will be removed. The area between Caldecott Lane and the freeway – an area now being used as a construction staging area – will be covered with an earthen berm, 20 feet high at the crest, and landscaped with grass and trees.
