The Milbridge Bridge Print E-mail

The Milbridge Bridge ConstructionThe Milbridge bridge is a stress-laminated deck post-tensioned with Glass-Fiber-Reinforced-Polymer (GFRP) tendons. It is the first stress-laminated bridge in the world constructed using GFRP tendons. GFRP tendons reduce prestress losses and eliminate the need to retension the bridge in service. A field-monitoring program demonstrated the advantage of GFRP tendons over steel threadbars in maintaining prestress levels. A report is available from AEWC.
