Keeping the Mississippi River Bridge on track

The Mississippi River Bridge is a cable stay bridge construction with two pylons. The bridge design includes two pylons projecting vertically from the Mississippi river bed with 6 m deep footings. The tower elevates to 123 m above the footing. The total project which includes interchanges and roadwroks will cost in excess of $667 million.

The Mississippi River Bridge project will create a new gateway between Illinois and Missouri to provide better connections to and through St. Louis. The project includes a landmark bridge structure, and the realignment and reconstruction of Interstate 70 and numerous local roads on both sides of the state line.

The bridge design includes two pylons projecting vertically from the Mississippi river bed with 6 m deep footings.      The general contractor is a joint venture between Massman Construction, Traylor Brothers, and Alberici Constructors (MTA). Main focus of the contractor is to stay on track while providing a safe working environment.

The Mississippi River Bridge is a cable stay bridge with two pylons. The bridge design includes two pylons projecting vertically from the Mississippi river bed with 6 m deep footings. The lower pylon is 20.7 m high x 6.7 m wide x 39.3 m long, projecting from the river in a Y configuration. The tower elevates to 123 m above the footing.

Construction on the two river towers is proceeding well. Both towers have reached the 60 m level, and are roughly half completed. They should be complete in late spring, and then crews will start attaching the cables and the framework for the driving surface.
