Attendees at World of Concrete (WOC), coming up Feb. 2 – 5 in Las Vegas, will have the opportunity to tour the Hoover Dam bypass and the Mike O'Callaghan-Pat Tillman Memorial Bridge.

The dam, was built between 1931 and 1936 by thousands of workers – more than 100 of whom lost their lives in the massive project.

People who take the tour will learn about the history and challenges of the two structures - as well as the admixtures used in the project's mix designs from docents, who will ride to the locations with them on a bus.

In addition to bus transportation, attendees will receive Hoover Dam tour tickets, and a boxed lunch.

The tour will take place on Sunday, January 31, 2016, from 12:30 pm- 5:30 pm and Friday, February 5, 2016 from 1:00 pm - 6:00 pm.

Hoover Dam & Bypass Bridge Tour Fee: $125.
