According to the 2017 ASCE Infrastructure Report Card (ASCE 2017), 9.1% of the U.S. bridges are structurally deficient. The majority of deficient bridges are in service on low-traffic volume roads, and these bridges should be replaced or repaired for public safety in a timely manner. As an alternative to the deficient bridges, a new bridge system made with cross-laminated timber (CLT), which exhibits desirable design strength and low environmental impacts, can replace them properly (APA 2016). CLT is the most advanced wood panel system comprising several sawn lumber layers oriented in alternating directions and bonded holistically with adhesive. The CLT bridge system can be a sustainable solution to expand the use of wood products and create new pertinent markets for rural economic development.
