Rehabilitations of Worthington Road Bridge
Plumstead Township, Bucks County, PA
In 2016, W.J. Castle, P.E. & Associates, P.C. completed the in-depth inspection and analysis of the bridge structure to determine the existing conditions and what structural repairs would be required to rehabilitate the stone arch bridge. Based upon the findings during the inspection, structural plans and specifications were finalized in 2017 for the bridge rehabilitation. Included in the analysis was the load rating calculations for the existing and proposed structural components.
The deteriorated stone arch was reinforced with a Contech Structural Plate Liner installed along the arch. Additional rebar and non-shrink grout filled the area behind the custom designed liner. Partial failures of the stone retaining walls/wingwalls were rebuilt using reinforced concrete moment slabs. The roadway in this area was rebuilt. Also, the bearing seats were rebuilt, new guiderail was installed, and stone riprap slope protection was added to the east end of the structure. Upon completion of the structural repairs, the bridge load rating can be removed. W.J. Castle provided construction inspection services. Final construction was completed November 2017.
