Project Details

This project involved replacement of the existing Steel I-Beam Bridge carrying SR 872 over First Fork of the Sinnemahoning Creek. The structure was replaced with a two-span P/S Concrete Spread Box Beam Bridge. While each span is 62’-6”, the overall project length is 740’-0” including approach roadway and drainage facilities.

Construction of the new downstream wingwalls was staged using shoring to accommodate the temporary road and bridge and to minimize impact to surrounding homes. Hydraulic modeling of the existing and proposed conditions was complicated by the fact that Freeman Run parallels SR 872 in this area and empties into First Fork directly upstream of the bridge.

A temporary one-lane road and bridge were used to route traffic around the construction area utilizing temporary traffic signals.

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.
