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.
We are very proud of our new office addition. Keller Engineers provided excellent guidance and support throughout our building project, which included key elements such as: structural recommendations, land development, environmental planning, and a beautiful rain garden. We knew we could trust the expertise of Adam Long, RLA and Brian Smith, PE in helping us create a practical and beautiful building and streetscape that enhances our neighborhood and the community.
