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.
