This program will build on our Part 1 program from last year. In Part 1, available on our website at http://www.hectv.org/video/3709/the-science-behind-the-new-mississippi-river-bridge-2/, we focused on the foundation work to build the bridge’s piers in the river and create the two cable-stayed towers. In Part 2, we’ll focus on the bridge’s cable-stayed design and building the road and deck surfaces. Why was a cable-stayed design chosen? How do the towers and cables work together to handle the seismic and physical forces at work on the bridge? How is the bridge deck and road surface put in place? How is the bridge connected to the roads used for access and egress? Ask these questions and more as you interact with engineers, designers and constructors who are building this new bridge over the Mississippi River in St. Louis.
