JMA designed a new rail yard at the Port of Stockton to support expanded interchange capabilities and capacities between the Port, BNSF Railway and Union Pacific Railroad. The yard is also served by Central California Traction Company, which interchanges with BNSF and UPRR. The project consisted of approximately 20,000 ft of new ballasted track for storing and handling BNSF cars at the Port’s 700 Yard facility, including two new lead tracks, 18 new turnouts, and 9 new yard tracks. The design included grading and drainage, utility encasement, access roads and associated demolition and the accommodation for Caltrans’ adjacent widening of SR-4 and the resulting modifications to the grade separation with the yard tracks and tie-in to BNSF’s mainline at the east of the yard. Several temporary track phases were designed to accommodate the bridge construction while maintaining BNSF operations.
