The concrete invert was dry in all the cells during this investigation. All <br />visible elements were fully inspected. A complete routine initial inspection of the visible elements was performed. <br />NUMBERING CONVENTION <br />The forward direction of Hansen Road is from south to north. The beginning of the structure is located on the south end. <br />HISTORY <br />The year of construction of 29C0485 is unknown. The year was estimated from the year of construction of 29C0475 located on Hanson <br />Road, south of this bridge. <br />The large percentage of truck traffic is due to trucks accessing major industrial warehouses located south of both Bridges 29C0485 and <br />29C0475. <br />The southern portion of Hansen Road located on the south side of the near by railroad tracks originally provided private access. <br />However, in 1993, under pressure by petitions for changes in land use by industrial developers, San Joaquin County rezoned the <br />southern portion of Hansen Road from private to general industrial. <br />MISCELLANEOUS <br />New routine photos were taken and a new routine map view photo was added during this investigation. See Photos 1 to 4. <br />DECK AND ROADWAY <br />The bridge identification was not visible. <br />SAFE LOAD CAPACITY <br />The load rating for this structure is being reviewed by SM&I Ratings Branch under Work Request 13210.
