UPCOMING OVERNIGHT LANE RESTRICTIONS

Southbound SR 51 will be narrowed to one lane between Indian School and McDowell roads nightly from 9 p.m. to 5 a.m., starting Monday, Sept. 21, and ending Friday morning, Sept. 25.

UPCOMING CLOSURE

Southbound SR 51 is scheduled to be CLOSED between Indian School Road and I-10 from 9 p.m. Friday, Sept. 25, to 5 a.m. Monday, Sept. 28.

ADOT advises drivers to use caution and be prepared to slow down and merge safely when approaching and traveling through all work zones.

NOTE: The currently uneven pavement conditions and asphalt remaining on SR 51 bridge decks are a temporary result of the required asphalt removal work completed the weekend of May 8-11. This is NOT the finished surface of the freeway. The remaining asphalt will be removed during upcoming bridge work. The freeway and ramps will be resurfaced to create a smooth driving surface using a treatment called diamond grinding. ADOT appreciates your patience as the project progresses over the next several months.

Overview

The Arizona Department of Transportation, in coordination with the Maricopa Association of Governments, is starting a pavement rehabilitation project along a 9.5-mile section of State Route 51, between Interstate 10 (Papago Freeway) and Shea Boulevard. The purpose of this project is to extend the life of the pavement and improve the driving experience and safety on the roadway.

The SR 51, I-10 to Shea Boulevard Pavement Rehabilitation project is included in the Regional Transportation Plan for Maricopa County and funded through Proposition 479, a countywide dedicated half-cent sales tax for transportation improvements approved by voters in 2024.

Project Elements

Removing the worn layer of rubberized asphalt
Repairing and diamond grinding the existing concrete pavement to create a smooth roadway surface
Repairing bridge decks and bridge joints
Repairing drainage and pavement under the SR 51 bridge at Camelback Road
Replacing lane striping and other pavement markings

Project Schedule

Construction began in March 2026, and is expected to end in late fall 2026. This schedule is subject to change due to weather and other unforeseen factors.

What to Expect

Work will require lane restrictions and some full closures on SR 51, on- and off-ramps and cross streets, and will occur primarily during overnight hours and on weekends to minimize traffic impacts. The freeway will not be closed in both directions at the same time.
Access to businesses and residences will be maintained.
ADOT will provide advance notice of scheduled restrictions and closures to email subscribers and on the project web page.
