This project included the replacement of the existing structurally deficient single-span concrete encased T-beam bridge supported on reinforced concrete abutments and wingwalls. The bridge, located over Chest Creek in East Carroll/Clearfield Townships, was posted for a six-ton weight limit.
The new structure is a single span, prestressed spread box beam bridge having a total structure length of approximately 60’ and a clear span of approximately 55’. The new structure carries two-way traffic and has a 22’ curb-to-curb width.
Additional improvements included placement of rock protection along both footings of the proposed structure and 400’ of approach roadway work with new guide rail on the approaches to the bridge.
We have worked with Keller Engineers for structural and civil engineering support on six projects over the past five years and have been very pleased with the results. Our projects tend to be complicated phased renovation/ addition projects calling for creativity in planning and construction. I have been particularity pleased with their responsiveness to issues that arise during construction which is of particular importance to us and our clients. Vern L.
