Complex stakeholder coordination and innovative use of technology for a major bridge crossing
Built in 1931, the existing US 60 Bridge over the Cumberland River needed to be replaced. At first glance, replacing the bridge seemed straightforward—the new bridge needed to be functional, safe, and economical. However, multiple stakeholders, navigation constraints, archaeological impacts, and a history of riverbank stability problems led to a complex interrelated design process.
We partnered with Seaman’s Church Institute to perform navigation simulation modeling of alignment and pier placement options. The innovative study, done in collaboration with the maritime industry and Coast Guard, resulted in early buy-in on required clearances. A subsequent bridge type and span arrangement study resulted in a span that met the design objectives and owner preference.
The modified warren truss features a modern design approach that improves efficiency and aesthetics while reducing life-cycle costs by eliminating verticals and sway bracing.
The project included environmental studies and permitting, public involvement, surveying, bridge and roadway design, geotechnical engineering, utility coordination, and construction phase support. The US 60 Cumberland bridge design met the varied needs of all stakeholders and will successfully replace its nearly century-old predecessor.
