ST. GEORGE — Motorists traveling on Interstate 15 along the Virgin River Gorge Sunday should expect traffic delays into the evening due to heavy traffic volume through the Gorge construction zone.

Heavy traffic volume has traffic backed up northbound on I-15 as you enter the Virgin River Gorge, Arizona Department of Public Safety Highway Patrol Sgt. John Bottoms said.

It is recommended drivers use Old Highway 91 until 8:30 p.m. Sunday, he said.

Motorists traveling through the area are advised to plan ahead and allow for traffic and construction delays and to drive with extra precaution.

“Please use caution if you use I-15,” Bottoms said. “Traffic will be moving very slowly as you come around some of the curves.

Bottoms urges motorists to always stay a safe distance from the vehicle in front of them when driving. Following too close, particularly in a construction zone, creates an unnecessary safety risk which oftentimes results in drivers skidding off into the median when the car in front of them stops or slows, he said.

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.

While one travel lane remains open in each direction, motorists should slow down and drive carefully through work zones and be alert for construction equipment and personnel.

Alternate route and tips for drivers

Those seeking to avoid the construction work in the Virgin River Gorge may take Highway 91 as an alternate route. The highway bypasses the gorge entirely, intersecting with I-15 at Littlefield, Arizona, to the south and connecting to St. George at the north via Santa Clara and Sunset Boulevard.
