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 teamed with Keller Engineers on several design-build projects for PennDOT. When selecting a designer, the more critical factors are trust and competence, more so than a low price. If your designer makes a mistake in quantities it can cost you a lot of money. We have stayed with Keller Engineers because we trust them to provide competent service at a competitive price.  S. Scott Grannas, Vice President Grannas Bros. Stone & Asphalt Co., Inc.
