Navy Drive Underpass at BNSF Railroad
Stockton, California

Geocon is the geotechnical engineer-of-record for the design and construction of the new Navy Drive underpass on the southern side of the Port of Stockton.  The Port of Stockton and the City of Stockton have planned to upgrade Navy Drive to a 4-lane roadway that will function as the main ground access to the Port.  The existing BNSF bridge that spans over Navy Drive will be replaced by two single-track structures, the second of which will service a second (shoofly) track parallel to the existing BNSF mainline.  An accelerated project schedule required a quick mobilization for our field exploration and close interaction with the structural engineer and team members during project design.  Geocon’s design-level geotechnical investigation evaluated liquefaction potential, settlement and a variety of deep foundation types for this critical transportation project.

Geocon’s design-level geotechnical investigation evaluated liquefaction potential, settlement and a variety of deep foundation types for this critical transportation project. Foundation recommendations were provided for driven H-piles and 30-inch diameter pipe piles and seismic design criteria was developed in accordance with the latest AREMA guidelines.  Our investigation report also included recommendations for embankment grading, flexible and rigid pavements, and temporary shoring. An accelerated project schedule required a quick mobilization for our field exploration and close interaction with the structural engineer and team members during project design.

Interesting Fact: The Port of Stockton is an inland Port accepting ship up to 900 feet long and weighting 60,000 tons but is more than 70 miles from the ocean.
