Locations of bridge crossings over navigable waters do not always allow high level crossings. Approaches may be in an urban area, where street level crossings are desirable, or there are insufficient approach lengths to allow the elevation for a high level crossing. Movable bridges provide a solution. ASCE's new webinar, Movable Bridges, will introduce the three common types of movable bridges used today -- bascule, vertical lift and swing bridges. You'll learn the advantages and disadvantages of each from an expert, 2013 ASCE Past President Andrew W. Herrmann, P.E., SECB, Pres.12.ASCE, principal with Hardesty & Hanover Consulting Engineers of Pittsburgh, Pa. Co-sponsored by ASCE's Structural Engineering Institute and ASCE Continuing Education, the webinar is set for Thursday, Nov. 15, from noon to 1 p.m. ET. Register today!
