In the northwest corner of Arizona, I-15 winds through a gorge alongside the Virgin River for a scenic drive. As travelers continue two miles past this gorge, they’re met with northbound and southbound bridges that carry the highway over the river.
When a $73 million construction project on these bridges was approved in 2021, the Arizona Department of Transportation (ADOT) knew it wanted to specify a Smart Work Zone to ensure the safety of the motoring public and roadway workers.
Several months into the massive project, and the 18-mile Smart Work Zone is successfully providing continuous traffic information to drivers and contractors.
