Analysis and Design for Replacement of the Burns Bridge

The paper describes analysis and design for the replacement of the Kenneth F. Burns Memorial Bridge (Route 9 over Lake Quinsigamond) in Shrewsbury and Worcester, Massachusetts. The replacement is actually two bridges, each consisting of five-span, post-tensioned, steel deck arches. The discussion includes the design approach, the construction sequence, the staged-construction analysis, the perched-pier foundation design, the approach for aesthetic design and detailing, and 3D modeling and visualization. The project uses the design-build project delivery method. The scope included fast-tracking of analysis and design to meet challenging project schedule milestones.
