PennDOT District 2-0, Potter County
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.
Penn Cambria School District has collaborated the last 4 years with the Keller Engineer’s team to complete a multi-phased paving and drainage project on our HS campus. I have personally worked with Adam Long, Brian Smith and Shawn Ritchey throughout the entire project and they made Penn Cambria feel like we were their only client. The personal attention to our needs and specific details of this project were second to none. The communication aspect of the Keller Engineer Team was outstanding. We trust their process, their design and their commitment to a quality project that when completed, we are all very proud of. Bill Marshall, Superintendent Penn Cambria School District
