Beginning today, May 5, northbound I-17 traffic will shift into the two newly constructed flex lanes that run adjacent to the two existing southbound lanes of I-17. The newly constructed lanes are not yet operating as “flex lanes.” The two flex lanes will be used only as a detour route for several weeks to move northbound I-17 traffic while the two existing northbound general purpose lanes are closed for ongoing work. | Arizona Department of Transportation
