ADOT completes new surface of reconstructed northbound Interstate 15 bridge


Virgin River Gorge drivers urged to allow extra travel time due to reduced speed limit to allow concrete to cure properly

PHOENIX – June 3, 2015 – (RealEstateRama) — At approximately 8:30 a.m. today, the Arizona Department of Transportation completed overnight work to pour a concrete deck on the newly reconstructed northbound Interstate 15 Virgin River Gorge Bridge No. 6 in the far northwestern corner of Arizona.

ADOT is urging motorists traveling through the Virgin River Gorge on I-15 to allow for extra travel time due to a reduced 25-mph speed limit that will remain in place for a 48-hour period as part of an ongoing bridge reconstruction project.

Completed deckThe reduced speed limit, which is expected to be lifted at 8 p.m. Wednesday, June 3, will allow for the fresh concrete to properly cure due to the reduced vibration from the lower-speed traffic.

Traffic delays up to an hour are possible.

The northbound 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 two-lane southbound bridge, which will also be replaced when the new, wider northbound bridge is completed this summer.

The completion of 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 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 additional construction equipment, crews and law enforcement personnel.
