Northbound traffic has been shifted into the two newly constructed flex lanes that run adjacent to the two existing southbound lanes of I-17. This temporary traffic shift is necessary while crews complete work on the existing northbound general purpose lanes between Coldwater Road and Sunset Point. The newly constructed lanes are not yet operating as “flex lanes.” The two flex lanes will be used only as a detour route to move northbound I-17 traffic while the two existing northbound general purpose lanes are closed for ongoing work.
