Drivers urged to allow extra travel time as ADOT completes deck pour on new southbound bridge
PHOENIX – The Arizona Department of Transportation is urging motorists traveling through the Virgin River Gorge on Interstate 15 in the far northwest corner of Arizona to allow for extra travel time next month due to a reduced 25-mph speed limit that will be in place for a 66-hour period as part of an ongoing bridge reconstruction project.
Beginning on Tuesday Feb. 9 at 6 a.m. and ending at midnight on Thursday , Feb. 11 , the reduced speed limit will be in place to allow crews to pour a new concrete bridge deck along the southbound Virgin River Bridge No. 6. The 66-hour period and reduced vibration from lower-speed traffic will allow the fresh concrete to properly cure.
Traffic delays up to an hour are anticipated.
During this period, all commercial truck traffic will be restricted to carrying loads to 40 tons or 80,000 pounds, the legal limit for trucks across the rest of the state.
The southbound bridge, located midway between Mesquite, Nevada, and St. George, Utah, at milepost 16, is closed for the reconstruction project and both directions of traffic are currently traveling on the newly widened two-lane northbound bridge, which was finished last summer.
The concrete deck pour is a significant milestone on the $27 million 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 Virgin River Bridge No. 6 project is completed this summer.
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 additional construction equipment, crews and law enforcement personnel.

ADOT works to inform the public about planned highway restrictions, but there is a possibility that unscheduled closures or restrictions may occur. Weather can also affect a project schedule.
