In episode 009 of the Civil Engineering Podcast, we take a closer look at Stan Musial Veterans Memorial Bridge in St. Louis, Missouri and provide project management advice from Jeff Church, PE and Gwen Lageman, PE, the engineers who worked on the project. Christian will break down the project and I will summarizes 6 challenges the project engineers encountered during the design and construction of the bridge and how communication plays an important role in the success of the project.
What You Can Learn From the Stan Musial Veterans Memorial Bridge Project:
How to help multiple people or organizations agree on one thing.
How to have good workflow communication when dealing with different organizations and government agencies on one project.
How to work with project specialists like archaeologists and keep the project moving along on schedule.
How to get buy-in from the community and ensure minority participation in the workforce is achieved.
How to know forecast the risks on your civil engineering project.
How to maximize your time if you’re managing multiple projects.

The story and design challenges behind the Stan Musial Veterans Bridge. #TCEPodcast Ep 009
Project Name: Stan Musial Veterans Memorial Bridge
The Stan Musial Veterans Memorial Bridge is also known locally as “The Stan Span,” it spans the Mississippi river just north of downtown St. Louis. Stan Musial was a 22-year veteran of the Cardinals, a first baseman, and widely considered to be one of the greatest and most consistent hitters in baseball history. He missed the 1945 season to serve in the Navy, hence the tie-in to “Veteran” in the bridge’s name.
Project Location: St. Louis, MO in the USA
Project Size:
The main span of the cable-stayed bridge is 1,500 feet (460 m) in length, part of a total span of 2,803 feet. It is 86 feet (26 m) wide. Cables stretch from the bridge deck to the tops of two A-shaped towers, which reach 435 feet (133 m) above I-70. The new bridge’s main span is supported by 1,000 miles (1,600 km) of 0.6-inch-diameter (15 mm) stay-cable strand, enough for nearly two round trips from St. Louis to Chicago.
Project Budget (Construction): $667 million

Was Project Over/Under Budget:
The cost of the original design of the bridge and surrounding area was estimated at nearly $1.7 billion. After which, both Illinois and Missouri state governments decided that they could not bear that cost, they called for a new design; this proposed a smaller size and was submitted in 2007 with an estimated cost of $667 million. Of the total, $264 million covered realignment of I-70 on the Illinois side, $57 million to realign I-70 on the Missouri side, and $346 million to build the bridge.
Project Completion (Month/Year or Expected Completion Date):
The project took a little over 4 years to complete and opened to traffic on February 9, 2014.
Special Design Features and/or Challenges:
Subsurface exploration showed thick deposits of low-density sand below the water table, which could liquefy during an earthquake. This is actually a real threat to the St. Louis region, coming from the New Madrid fault. Several ways to reduce the risk were considered, including in-situ densification of the sands,
