Clients / San Joaquin Regional Rail Commission (SJRRC)

Project Dates: April 2012 –August 2013
Construction Cost: $4,350,000

San Joaquin Regional Rail Commission (SJRRC) has retained the services of the Hanna Group for construction of a railroad bridge over Miner Avenue in Stockton, California. The proposed undercrossing is located directly north of the Robert J. Cabral Station and west of the existing Union Pacific Railroad undercrossing (bridge) for both Fresno Subdivision mainlines.

Miner Avenue is a major four lane arterial road through Stockton and traffic control and pedestrian protection will be important. Once complete this portion of the Miner Avenue Bridge will be owned and maintained by SJRRC. The Project Miner Avenue Undercrossing Project generally consists of but is not limited to: Removal of portions of the existing Structure (retaining walls, wingwalls, sidewalk, planter), Installation of 4’ diameter CIDH piles with permanent steel casing, construction of steel superstructure, Prestressed Concrete Fascia Girders, Decorative Wall and Jack & Bore underneath the railroad tracks. Due to the unique features of this project, THG was selected to its specialized construction expertise in successfully managing the completion of the project. This project requires expertise on particular construction techniques such as steel fabrication and construction, familiarity with camber geometry for fabrication, experience with technical construction stages and extensive coordination with Union Pacific Railroad.
