Standard Plans for Southern Pine Bridges
The development of standardized timber bridge plans and specifications is a key element in improving design and construction practices. The bridge plans presented were developed as a cooperative effort between the USDA, Forest Service, Forest Product Laboratory (FPL), the University of Alabama, and Southern Pine Council....designing loads for AASHTO HS 20-44 and HS 25-44 vehicles, and two options for live-load deflection criteria.
