San Francisco Bridge
The Bay Bridge joining Oakland and San Francisco made headlines in 2009 when it was shut down for a major renovation. To make the fix, Riley joins the engineering team tasked with cutting a football field-sized section of roadway from the bridge and replacing it - in just 72 hours! With traffic halted and the world watching, the team encounters some unexpected challenges. A crack puts the operation on hold and requires custom-made colossal steel brackets. The clock is ticking.

S3 E1
Rocky Mountain Rigging
Riley's headed to the Wild West - just outside Yellowstone Park near Cody, Wyo., to rebuild one of the first ski lifts in the country. Riley joins cowboys of the ski lift industry to rehab 10 towers from piles of used parts. Building just outside of picturesque Yellowstone in the rugged back country presents additional challenges. To get several of the towers up the mountain, the guys bring in a special helicopter to crane the materials into place. It's an incredibly delicate operation.

S3 E2
Extreme Bridges
Riley crosses the pond to scale three iconic bridges in the U.K. The famed Tower Bridge in London is being restored, and the lead paint being stripped must be contained. In Scotland, he'll construct scaffolding at the top of the Forth Bridge, a vertigo-inducing 367 feet over the water! Just upriver, he helps implement an experimental technique to prevent a suspension bridge from collapsing.

S3 E3
Fixing Vegas
Riley travels to Las Vegas to help high-flying Cirque du Soleil solve a real showstopper of a problem - one of the world's largest, most technologically advanced stages is broken. To make the repair, Riley and team have to lower the 80-ton stage and take a look inside - a process never before attempted. While in Sin City, Riley helps repair some of most amazing spectacles on the Strip, including the world's largest video screen and high-tech water cannons in the Bellagio fountain.

S3 E4
Extreme Heights
Riley is going to new heights. He'll hang over the edge of Las Vegas' tallest building to fix the X-Scream, a thrill ride on the Stratosphere. One of the critical safety measures needs replacing, and Riley joins the ride's head of maintenance on the very edge of the track, 800 feet above the ground, to make the fix. Then he'll dangle 500 feet over the side of the Hoover Dam to retrieve trash. Upriver from Niagara Falls, he'll hang over an unstable, overgrown cliff to eliminate loose rocks.
