The $2.8 million project started in January and included upgrading the southbound bridge surfaces, girder repairs and other related work on Virgin River Bridge No. 2 (milepost 13), Bridge No. 3 (milepost 13) and Bridge No. 7 (milepost 22).
With completion of work on these three bridges, traffic restrictions have eased through the Virgin River Gorge. However, a work zone will remain in place through 2016 for the reconstruction of Virgin River Bridge No. 6 (milepost 16), approximately 20 miles south of St. George, Utah.
In April, ADOT started an extensive rehabilitation project on Virgin River Bridge No. 6, which includes replacing the bridge’s superstructure (girders, deck and railings), as well as widening the roadway through the narrow Virgin River Gorge. When this section of highway was built, it was the most expensive rural interstate highway built, per mile, when it was completed in 1973 after a decade of construction.
Recently, ADOT started work that will eventually serve as the foundation of the new bridge. The $27 million project is the only active project on Arizona’s portion 29-mile-long of I-15, which directly connects Nevada and Utah and is a heavily-traveled commercial and economic corridor linking southern California with the Rocky Mountain region.
With limited alternate routes due to the remote location of the I-15 Virgin River Gorge corridor, ADOT urges drivers traveling between Mesquite, Nevada, and St. George, Utah, to plan ahead, allow extra travel time, slow down and drive carefully through the Virgin River Bridge No. 6 work zone. I-15 is narrowed to one lane in each direction at the bridge project and delays are possible.
ADOT works to inform the public about planned highway restrictions. Unscheduled restrictions or closures may occur.
