The North Yarmouth Bridge Print E-mail

The North Yarmouth Bridge ConstructionThe North Yarmouth Bridge is a stress laminated deck. It consists of longitudinal parallel-chord Metal- Plate-Connected (MPC) trusses that are transversely post-tensioned. As in the Byron bridge, the MPC trusses extend the span of solid stresslam decks and provide for exceptional stiffness. Deflections under HS25-equivalent dump trucks was less than L/1600. A 5-year monitoring report is available.
