Bridge girder installation begins Monday: Motorists reminded to plan ahead for delays

As part of the ongoing bridge rehabilitation work underway along the Virgin River Gorge in the far northwest corner of Arizona, crews will begin girder installation on Virgin River Bridge No. 6 beginning Monday, Feb. 23 through March 23. Motorists traveling on Interstate 15 between Mesquite, Nevada, and St. George, Utah are reminded to plan ahead for construction delays up to 20 minutes, according to the Arizona Department of Transportation.

Crews are scheduled to install bridge girders Monday through Thursday, from 6 a.m. to noon. This work will require intermittent 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.

For more information on the intermittent traffic breaks that will occur, watch the following ADOT YouTube video:

Drivers should allow for up to 15 minutes extra travel time during regular construction activities, 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.
