Project Details

This project involved replacement of the existing bridge carrying Old Mill Road over North Spring Creek. Improvements consisted of replacing the existing structurally deficient single lane bridge with a new single lane P/S Concrete Spread Box Beam structure. With minor profile adjustments, the new structure was constructed on the existing horizontal roadway alignment. Drainage work, including new inlets, was included to better control drainage adjacent to the historic Hudson Grist Mill property.

Safety improvements were made to the approach roadway and at the intersection of SR 0655 where site distance was a challenge. This project also required improvements that met design criteria to fit into the community context while limiting impacts to the historic mill, the East Broad Top Railroad (a National Historic Landmark) right-of-way, and area wetlands. The mill race drainage structure was required to be extended to accommodate the widened roadway near the mill and a new reinforced concrete headwall was constructed and faced with the masonry stonework from the original headwall.

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
