California’s State Route 1 is one of the most scenic routes in the world. However, the Big Sur coastline along this highway also is geologically active and unstable. Broken and weak rocks are covered with eroded soils that are highly prone to landslides. As a result of ground water, surface water infiltration, erosion and storms, this area – and particularly Pitkins Curve – has been in constant need of repairs since 1937. Extensive studies revealed that landslides and resulting highway damage would continue to occur indefinitely without a comprehensive solution. Therefore, Caltrans determined that the safest and most cost-effective solution would be to bridge Pitkins Curve, and build a rock shed at Rainrocks, a neighboring area of roadway instability. Golden State Bridge Inc., based in Martinez, Calif., won the $29.4-million contract, and has been on the job since December 2009.
