FLAGSTAFF – Access to the I-17 southbound off-ramp at Exit 337 (JW Powell Boulevard) will be closed from 7 a.m. to 9 a.m. on Tuesday, Oct. 21, to complete preparations for new ramp construction. This work is part of the intersection improvement project currently underway which includes a new roundabout and realignment of SR 89A/Beulah Boulevard.

The recommended detour for southbound I-17 connections to the Flagstaff Airport and to SR 89A is to continue southbound on I-17 past Exit 337, then exit at Kachina Trail/Mountainaire Road (Exit 333). Detour signage will be in place to assist travel in the area.
