The CSVT River Bridge is a key component to a new 13-mile stretch of highway near Selinsgrove and Northumberland, Pennsylvania. The bridge is a six-lane, 15-span, 7/8-mile-long multi-girder structure comprised of three independent 5-span steel superstructure units with a maximum span length of 350'. The bridge substructure consists of hammerhead piers ranging from 70'to 180'above the footings. The height of the piers and the proposed pier stem cross-section places the piers outside AASHTO slenderness limits, which required advanced analyses of second-order effects in lieu of the typical approximate method used for estimating second-order effects. This presentation covers the challenges of designing and optimizing long spansteel multi-girders, lateral bracing, diaphragms, and slender piers, as well as the consideration of substructure system interaction. Construction challenges and issues will be discussed as well.
