The Theatre Drive/Hwy 46 Realignment was funded by the American Recovery and Reinvestment Act of 2009 and was a Caltrans Local Assistance project. It is located in the Paso Robles area of San Luis Obispo County and involved the construction of a new intersection at Theater Drive and Highway 46 West. Traffic signals supported by caisson or spread footing foundations were constructed at the intersection. Theater Drive was realigned between an existing Orchard Supply Hardware and an existing Hampton Inn.

Earth Systems’ services included a materials report for the new intersection and Theater Drive realignment, and foundation recommendations for the traffic signals. During construction, Earth Systems provided field materials testing and special inspection services in accordance with Caltrans requirements.
