T-536 Over Little Fishing Creek

Columbia County County Bridge #89 is a single span steel through pony truss located in a rural area of Greenwood Township, Columbia County. The structure was closed to traffic during a routine bridge inspection due to section loss on several steel stringers. Columbia County Commissioners retained Professional Design Services from Larson Design Group to design and administer the rehabilitation of the truss. LDG was scoped to complete repairs to the structure to carry minimal vehicle loads due to the overall condition of the structure and limited funding. Services performed by LDG included: design of replacement stringers, floorbeam strengthening, load rating analyses of the structure, DEP Permit submission and approval, construction drawings, bid document preparation, bid advertising and letting, and construction administration and observation of the project.

The project was completed on schedule and under the construction budget.
