Phoenix, AZ – Drivers in the Phoenix area are being urged to prepare for a significant weekend traffic disruption as a major stretch of State Route 51 is set to close for ongoing roadway improvements.
According to the Arizona Department of Transportation, southbound SR 51 (Piestewa Freeway) will be closed between Glendale Avenue and Indian School Road beginning 9 p.m. Friday through 5 a.m. Monday. Officials say the southbound SR 51 on-ramp at Northern Avenue will also be closed during this time.
The closure is part of a broader pavement rehabilitation project spanning approximately 9.5 miles of SR 51 between Interstate 10 and Shea Boulevard. Transportation officials say the goal is to extend the lifespan of the roadway while improving driving conditions and overall safety for motorists.
Drivers traveling through the area are advised to follow a designated detour route. According to ADOT, motorists should use westbound Glendale Avenue to southbound 16th Street, then proceed to eastbound Indian School Road to reconnect with southbound SR 51 beyond the closure.
Traffic delays are expected throughout the weekend, especially during peak travel times. Officials recommend allowing extra travel time or seeking alternate routes to avoid congestion.
ADOT also noted that no closures are scheduled for the following weekend. However, work is expected to resume in the southbound lanes during the weekend of April 10-13.
Motorists are encouraged to stay updated on real-time traffic conditions and plan ahead as crews continue work aimed at improving one of the region’s busiest commuter corridors.
