Klingner was hired by the City of Burlington, IA, after one side of a double barrel stone arch storm sewer (circa 1878) collapsed beneath the Burlington Junction Railroad. A temporary realignment of the track was designed with coordination from Burlington Junction Railroad and the City to reestablish rail service in a timely manner. This included excavation near the railroad and the design and building of a temporary structure to support the track. The City of Burlington provided historical site records and timely input regarding budgets, timelines, and procurement requirements.
For the final design, Klingner’s engineers developed a new cast-in-place reinforced concrete three sided structure that tied into the existing sewer. Sheet piling was installed to retain the railroad embankment for the track during construction. Once construction was completed, the rail line was returned to its original alignment.
