Lindbergh Viaduct Historical Rehabilitation

Pennsylvania DOT - District 5

Project Summary

Lindbergh Viaduct, built in 1927 and located in Pendora Park in Reading is National Register listed. The 800'-long viaduct was composed of 13, open spandrel arch spans. The roadway is on a horizontal curve and is supported by tangent arch ribs and variable-width piers. The original railings were removed in the 1960s, but otherwise the viaduct was complete but deteriorated. PennDOT’s goal was to preserve the viaduct if possible rather than replace it. TranSystems performed an in-depth inspection and structural analysis and rating using STAAD III for the finite element computer program. Rehabilitation and replacement alternates for the severely deteriorated approach spans and reinforced concrete repairs to the main spans were developed. Through interagency consultation, it was determined that the approach spans, a poor original design that accelerated deterioration, could be eliminated and that the main spans could be rehabilitated in accordance with The Secretary of the Interior’s Standards. Deteriorated material was replaced with sound material to duplicate the original architectonic detailing. TranSystems’ historians and engineers collaborated on developing the design to preserve the viaduct and to complete the Section 106 and 4(f) evaluation processes successfully.
