Rockfall containment work underway near Interstate 15 Virgin River Bridge No. 6

ADOT advises drivers traveling through Virgin River Gorge to allow extra travel time

PHOENIX — Motorists traveling on Interstate 15 between Mesquite, Nevada, and St. George, Utah, along the Virgin River Gorge in the far northwest corner of Arizona, are reminded to plan ahead for construction delays up to 15 minutes, according to the Arizona Department of Transportation.

In addition to the ongoing construction work on Virgin River Bridge No. 6, crews are currently removing rocks within the work zone through Friday, Jan. 23. This rockfall containment work requires rolling lane closures to allow for the safety of both the construction crews and the traveling public.

While one travel lane will remain open in each direction, motorists are reminded to slow down and drive carefully through work zones and be alert for construction equipment and personnel.

The $27 million rehabilitation of Virgin River Bridge No. 6 began in March 2014, and is anticipated to be completed in 2016. This significant project includes the replacement of the bridge’s superstructure (girders, deck and railings), as well as widening the roadway through the narrow passage of the gorge.  

Drivers should allow for up to 15 minutes extra travel time during construction, weekdays from 6 a.m. to 6 p.m. Additional delay time may occur on weekends due to heavier traffic volume and special events.

The busiest travel times through the Gorge are Friday through Sundays. With limited alternate routes due to the remote location of the I-15 Virgin River Gorge corridor, ADOT urges drivers to plan ahead and allow extra travel time.
