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 teamed with Keller Engineers on several design-build projects for PennDOT. When selecting a designer, the more critical factors are trust and competence, more so than a low price. If your designer makes a mistake in quantities it can cost you a lot of money. We have stayed with Keller Engineers because we trust them to provide competent service at a competitive price. S.
