Work complete on three I-15 bridges through Virgin River Gorge

New project to rehabilitate Bridge No. 1 to begin next year

PHOENIX – An Arizona Department of Transportation project improving the decks of three Interstate 15 bridges through Virgin River Gorge is complete and all restrictions have been lifted. 

Work began in April 2019 to resurface the decks of Bridge No. 2 and Bridge No. 5, while Bridge No. 4 received a new deck. 

For this project, ADOT used a first-of-its-kind queue warning system that included portable message boards informing drivers of stop-and-go traffic ahead. Using equipment that detects traffic in real-time, the system is designed to help reduce collisions as traffic builds.

Crews plan to return to lay down permanent striping on the bridges within the next week, so drivers should expect some minor delays while that work is completed.

Early next year, ADOT will begin work to rehabilitate and add wider shoulders to Bridge No. 1 near Littlefield.
