The Arizona Department of Transportation will begin guardrail repair on Monday, July 21 on Interstate 17 from Table Mesa Road to just south of State Route 169, and will continue through Wednesday, July 23.

The work between mileposts 235 and 274 requires alternating lane restrictions in both directions and intermittent shoulder closures from 6 a.m. to 6 p.m. each day. No delays are expected.

The speed limit through the work zones will be reduced to 45 mph during work hours. Arizona Revised Statute 28-710 §B. provides for double the fine for speeding through a marked highway work zone.
