The New I-70 Mississippi River Bridge-Design Issues and Solutions

St. Louis, Missouri's new cable-stayed Mississippi River Bridge will carry 8 lanes of traffic on a main channel span of 610 m (2,000 ft) with 4 full shoulders resulting, in each direction, in a 21.9 m (72 ft) wide roadway. When completed it will be the western hemisphere's longest bridge of its type due to its main span length, and one of the world's widest cable stayed bridges. Extensive public involvement, owner participation, and engineer-architect design team integration resulted in the bridge's major appearance features and bridge type. Design and detailing features were significantly affected by several owner requirements intended for long-term durability promotion, including a 150 year service life, future deck replacement design, fatigue design, two-level seismic design use with a 2,500-year event high level design and an associated "Service Immediate" performance level. The authors examine a deck erection sequence and other resulting unique features.
