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.


[Brian Moore] has kept me informed every step of the way on the front lines of this project. With this being my first project and me still being on a huge learning curve, that speaks volumes about Keller Engineers and Brian’s commitment to your customers.
