The Arizona Department of Transportation will perform routine maintenance on northbound Interstate 17 at Table Mesa Road on Tuesday and Wednesday, July 28 and 29 between 7 a.m. and 4 p.m.

Motorists should be prepared for a right lane restriction and intermittent shoulder closures between mileposts 236 and 237 to allow for a safe work zone for maintenance crews. Minimal delays are expected.

The speed limit through the work zones will be reduced to 45 mph during work hours.
