Drivers on Interstate-40 will need to plan accordingly when ADOT closes Exit 191, the Flagstaff Business Loop, Wednesday for a couple of days. Crews will repair five miles of pavement between mileposts 190 and 195. ADOT will close the westbound off-ramp on Wednesday and eastbound on and off ramps on Thursday. Eastbound I-40 on and off ramps at the exit and the westbound I-40 off ramp will be closed on Friday for shorter durations. Traffic that usually uses Exit 191 will be detoured to the next exit to re-enter the interstate toward their destination. Drivers going through the work zone will need to use caution, slow down and watch for work crews.
