The Mike O'Callaghan-Pat Tillman Memorial Bridge is viewed from a road below it near the Hoover Dam. An American flag sits atop a stone wall in the foreground and blows in the wind. A bag of Armorstone overlay aggregates is hoisted by a forklift above a hopper. The side of the bag shows a logo that says A closeup of small stones coming out of a chute. The small stones are a type of aggregate called Armorstone Overlay Aggregates. A semi truck drives on a roadway that has an epoxy polymer-Armorstone treatment. This means that the surface is covered in a slick plastic-like coat studded with tiny rocks that add friction to the surface. Dozens of people walk along a pedestrian walkway out to the middle of the Mike O'Callaghan-Pat Tillman Memorial Bridge. The supporting arch of the bridge can be seen below, contrasted with the rusty crags of the surrounding canyon. Vehicles drive US-93 North on the other side of a barrier next to the pedestrian walkway. The Mike O'Callaghan-Pat Tillman Memorial Bridge is viewed from a cafe at Hoover Dam. Patio umbrellas can be seen on the lower left-hand corner of the photo. The Memorial Bridge stretches out in the distance over 200 feet above. Very tiny people stand on the bridge and look down.

Description

The Mike O'Callaghan-Pat Tillman Memorial Bridge was built to reroute traffic away from the top of the Hoover Dam. It crosses over Black Canyon, connecting Arizona and Nevada via U.S. Route 93. An estimated 15,000 vehicles cross the bridge every day.

Washington Rock worked with Las Vegas Paving to ship enough Armorstone for six bridge deck overlays near the Hoover Dam, including the Memorial Bridge.

Materials

180 tons of Armorstone Overlay Aggregates

Highlights

The Memorial Bridge, with a length of 1,900 feet and a span of 1,060 feet, required nearly 2 million square feet of product. Las Vegas Paving project manager Coy Nelson appreciated not only the quality of the product but also the communication Washington Rock provides.
