The Arizona Department of Transportation is urging motorists with travel plans on Interstate 15 in the far northwestern corner of Arizona, midway between Mesquite, Nevada, and St. George, Utah, to plan ahead and allow extra travel time up to an hour for a bridge deck pour beginning Monday, June 1 from 8 p.m. to Wednesday June 3rd at 8 p.m.

While this work will take place at night, the speed limit will be reduced to 25 mph beginning Monday night through Wednesday June 3rd at 8 p.m. This time will allow for proper setting of the fresh concrete. Drivers need to be aware of additional construction equipment, crews and law enforcement at the Virgin River Bridge No. 6 (milepost 16) work zone.

The concrete deck pour is a significant milestone on a $27 million major reconstruction project that began in 2014, and 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 highway is currently narrowed to one lane in each direction through the work zone until the project is completed in 2016.

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

To stay up to date with the latest highway conditions around the state, visit the ADOT Traveler Information Center at az511.gov or call 511; outside of Arizona dial 1.888.411.ROAD (7623).
