Interstate 15 Virgin River Bridges 

ADOT continues to upgrade the Virgin River Bridge structures. This summer, construction was completed on a $2.8 million project, which included rehabilitation on several southbound bridge surfaces: Virgin River Bridge No. 2 (milepost 13), Bridge No. 3 (milepost 15) and Bridge No. 7 (milepost 22). View a project flyer with a map of the area.

In April, ADOT started an extensive rehabilitation project on Virgin River Bridge No. 6, which includes replacing the bridge's superstructure (girders, deck and railings), as well as widening the roadway through the narrow passage of the scenic Virgin River Gorge. When this section of highway was built, it was the most expensive interstate freeway ever built, per mile, when it was completed in 1973 after a decade of construction.

The $27 million project is the only active project on Arizona's 29-mile-long portion of I-15, which directly connects Nevada and Utah and is a heavily traveled commercial and economic corridor linking southern California with the Rocky Mountain region. Construction on the superstructure will continue through 2016.

With limited alternate routes due to the remote location of the I-15 Virgin River Gorge corridor, ADOT urges drivers traveling between Mesquite, Nevada, and St. George, Utah, to plan ahead, to allow extra travel time, to slow down and to drive carefully through the work zone. I-15 will be narrowed to one lane in each direction at each of the bridge projects, and delays are expected.

Please view the Traffic Alerts page for current I-15 restrictions before traveling. Unscheduled restrictions or closures may occur. To stay up to date with the latest highway conditions around the state, visit the ADOT Traveler Information Center at az511.gov or call 511.
