Timber-Based System Shows Promise for Replacing Structurally Deficient Bridges on Low-Volume Roads

Posted: Jun 21, 2023

Research at South Dakota State University shows that a new bridge system made with cross-laminated timber (CLT), which exhibits desirable design strength and low environmental impacts, offers a suitable replacement for bridges on low-volume roads. CLT is an 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 for replacing structurally deficient bridges that will expand the use of wood products and create new markets that will stimulate rural economic development.
