I-15 bridge improvement work progresses in Virgin River Gorge

Motorists reminded to plan ahead for delays; Traffic switch to begin on March 3

PHOENIX — Construction work on a series of bridge rehabilitation projects along the Interstate 15 Virgin River Gorge corridor in Arizona is underway, and motorists traveling between Mesquite, Nevada, and St. George, Utah, should plan ahead for delays in both directions through the work zones, according to the Arizona Department of Transportation.

On Monday and Tuesday, March 3-4, northbound and southbound traffic is scheduled to be switched to the northbound lanes at Virgin River Bridge No. 2 and Bridge No. 3 (both at milepost 13, approximately 15 miles north of Mesquite, Nevada) and Bridge No. 7 (milepost 22, approximately 15 miles south of St. George, Utah) to allow work on the southbound bridge deck surfaces to begin.

I-15 will be narrowed to one lane in each direction at each of the bridge locations and delays are expected. Anticipated completion for this $2.8 million improvement project is this summer.

Drivers should allow 15 minutes extra travel time weekdays from 6 a.m. to 6 p.m. Additional delays may occur on weekends due to heavier traffic volumes and special events — including spring break from mid-March through late April.

Next month, ADOT is expected to start the reconstruction of Virgin River Bridge No. 6 (milepost 16, approximately 21 miles south of St. George, Utah). This significant $27 million rehabilitation project will include the replacement of the bridge’s superstructure (girders, deck and railings), as well as widening the roadway through the narrow passage of the gorge.

With limited alternate routes due to the remote location of the I-15 Virgin River Gorge corridor, ADOT urges drivers to plan ahead, allow extra travel time, slow down and drive carefully through the work zone, and be alert for construction equipment and personnel.

ADOT works to inform the public about planned highway restrictions. Unscheduled restrictions or closures may occur, and construction schedules are subject to change.
