I-70 Stan Musial Veterans Memorial Bridge, St. Louis, Missouri

A Massman led joint venture constructed this award-winning cable-stayed bridge across the Mississippi river in St. Louis, Missouri. This project was completed for Missouri Department of Transportation on budget and schedule.

The cable-stayed portion of the project consists of a 1,500 foot long main span (the third longest in the US) with two 636 foot long end spans. Each of the two main (river) piers are founded on six 11’-6” diameter drilled shafts with 11’ diameter rock sockets. The 400 foot tall delta shaped piers support the superstructure with 34 pairs of stay cables. When completed, the new bridge will carry two lanes of Interstate 70 traffic each way between downtown St. Louis and the Metro-East. (Rendering courtesy of MoDOT)
