The Structural Engineers Association of Illinois is pleased to announce our first Movable Bridge Workshop! The event provides an opportunity for structural engineers to learn best practices in the design, operations, and maintenance of movable bridges, lessons learned, and the interdisciplinary coordination required on these heavy movable structures.  Chicago has the most movable bridges of any city in the world and several of them are scheduled for significant rehabilitations.  This workshop will provide an excellent opportunity to hear from both local and national specialists in movable bridges.
