Tucked at the end of its long, narrow channel, it handles primarily agricultural products -- rice, wheat, and other bulk goods that the Sacramento Valley produces in abundance -- rather than the shipping contai...

The channel has found a second act as part of the California Green Trade Corridor, a project linking the ports of Oakland, Stockton, and West Sacramento into a marine highway intended to reduce truck traffic on Northern California's congested freeways. The concept is straightforw...
