From the Hoover Dam Visitors Center, you can see the cast-in-place arches of the Colorado River Bridge taking shape downstream.

Visitors to Hoover Dam are beginning to see the new concrete construction landmark taking shape about 1500 feet downstream. The Colorado River Bridge will connect the Nevada and Arizona sides of the new highway that will bypass Hoover Dam.

World of Concrete attendees who went on the Editorial Tour, sponsored by Sika Corp., Feb. 1 and 6, met Jeff St. John, deputy project superintendent with contractor Obayashi/PSM JV, who gave an update on the $114 million project. Both sides of the bridge deck are complete, and he expects the arches to meet in the middle, high above the Colorado River, this summer.

In addition to St. John's presentation and the Visitors Center tour, attendees listened to concrete historian Luke Snell talk about the 1930s-era project's trials and tribulations, including the bidding process, awful weather conditions, and concrete production.

“As we view the Hoover Dam, we need to remember it is more than a beautiful structure,” Snell said. “It has a continuing legacy that changed the construction industry. This was the biggest project of its time, and many new construction procedures were developed as a result of this project.”

Sika Corp. is again sponsoring a tour of the Colorado River Bridge project at next year's World of Concrete. For more coverage, see video of Snell's presentation and additional .
