Starting this week, billboards, social media and television and print media will carry messages urging thousands of motorists, especially in Mesa and the rest of the East Valley, to prepare for three to four years of disruptions in their driving routines. Itâs not exactly Armageddon that the Arizona Department of Transportation will be heralding. But it wonât be a walk in the park, especially for car and truck traffic on I-10. And even if you donât use I-10, you can expect significant increases in traffic along all the freeways in the East Valley and even major arterials as motorists try to evade the inevitable tie-ups that will be caused by the I-10 Broadway Curve Improvement Project.
