How Do You Pour Concrete Under Water?

Bridges have always amazed me. As someone who works with engineers but does not have that background, the process of constructing a bridge just seems incredible. My burning question has always been about how the foundation is built and holds strong. Really, how DO you pour concrete under water?

How do you pour concrete underwater?
My question has been answered, and with a neat little graphic to boot. The New Mississippi River Bridge project in St. Louis is offering a virtual tour that answers all of your questions about how these massive structures take shape. Don't miss the pictures of the coffer dam, where crews are able to work on the riverbed.

If you're in the St. Louis area, you can see these steps in person. On the last Friday of each month, schedule a tour where you can see the action up close. Check out the specifics here
