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.
For over 20 years I have had the privilege of working with Keller Engineers and their staff of surveyors, and civil and structural engineers on over $150 million worth of work. During these project relationships and partnering opportunities, my architectural teams have received nothing but premium professional services and courtesy towards my own staff, clients and prospective clients with stellar attention given to building and site details, client responsiveness and peer respect. I look forward to many more teaming opportunities and urge any other architectural firms, municipalities or clients who have not worked with Keller Engineers to do so. You will be pleasantly surprised! Richard L. Karcher, AIA, NCARB
