Following the Labor Day holiday weekend Sept. 5-7, southbound traffic will also be diverted onto the northbound bridge until construction is completed on the southbound bridge.
Those seeking to avoid the construction work in the Virgin River Gorge may take Highway 91 as an alternate route. The highway bypasses the Gorge entirely, intersecting with I-15 at Littlefield, Arizona, to the south and connecting to St. George, Utah, at the north via Santa Clara and Sunset Boulevard. See map inset.
ADOT Bridge rehabilitation project
Bridges in the Virgin River Gorge were originally constructed in the 1970s and are in need of upgrades and repairs. When this section of highway was built, it was the most expensive rural interstate highway built, per mile, and was completed in 1973 after a decade of construction.
ADOT has completed work on three of the bridges thus far, specifically surfaces for Virgin River Bridge No. 2 at milepost 13, Bridge No. 3 at milepost 15 and Bridge No. 7 at milepost 22.
Work began on Bridge No. 6 in the spring of 2014 and is currently anticipated to be completed in 2016. Bridge No. 6 involves a $27 million rehabilitation project replacing the bridge’s superstructure (girders, deck and railings), as well as widening the roadway through the narrow passage of the gorge.
