Construction on a major Interstate 15 reconstruction project on Virgin River Bridge No. 6 (milepost 16) is more than halfway complete. After finishing the northbound section of the bridge this summer, crews are now working to construct the new southbound bridge.

While the roadway will continue to be narrowed to one lane in each direction at this work zone, motorists should be prepared for additional travel delays up to 20 minutes while crews remove loose rocks near the southbound side of the bridge structure from Monday, Oct. 12 through mid-November.

Intermittent traffic breaks will be necessary during work hours, 6 a.m. to 6 p.m. on weekdays. For more information on how ADOT uses traffic breaks, please visit the ADOT YouTube webpage:

This $27 million improvement 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. The project is scheduled for completion in 2016.

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.
