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.

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
