Happy Valley Road Bridge

Larson Design Group (LDG) provided bridge inspection and design services for the Happy Valley Road Bridge in Columbia and Northumberland Counties, Pennsylvania. The bridge is important to Knoebels Amusement Park and is used daily by employees and campers going to and from the campground at the park. The bridge’s concrete deck was deteriorating, as were the concrete curbs and bridge railings. The construction was to be completed before the Independence Day holiday to meet the traffic demands of the amusement park. The Independence Day holiday is the busiest time of the year for the park.

The rehabilitation included replacing the curbs and railings, the concrete end diaphragms, the concrete wing caps, and the bridge deck, which was replaced with a composite reinforced concrete deck. Grouted rock scour protection was constructed around the pier and the entire steel superstructure was blast cleaned and painted. The project also included improvements to the approach roadway and the installation of guide rails.
