Frazier Covered Bridge

For this project, Larson Design Group provided preliminary and final design services and construction inspection for the rehabilitation of a 78 food long timber burr arch truss timber covered bridge. The project consisted of a complete dismantling and re-erection of the existing timber superstructure and designing new reinforced concrete substructures with an aesthetically pleasing architectural surface treatment. The truss was rehabilitated to accommodate a 3-ton live load vehicle, its own dead load, wind loads, and snow loads. Approximately 67% of the existing deteriorated timber members were replaces with new full sawn timber members.

LDG coordinated with Pennsylvania Department of Transportation (PennDOT) Engineering District 3-0, Lycoming County Commissioners, and Pennsylvania Historical and Museum Commission (PHMC) to discuss the proposed rehabilitation project and receive concurrence of the proposed work from PHMC, since the existing structure is listed on the National Register of Historic Places.
