Pinnacle Peak Road reopens east of I-17 after culvert work

Road had been closed since last month for drainage project

PHOENIX – A short section of Pinnacle Peak Road is open as planned east of the Interstate 17 interchange in north Phoenix following work that began last month to replace a concrete drainage culvert under the roadway.

The culvert work, which started on Feb. 19, is part of the Arizona Department of Transportation’s $50 million project to reconstruct the I-17 interchanges at Pinnacle Peak and Happy Valley roads.

A new, larger culvert is now in place to pass along storm runoff.

ADOT worked closely with the city of Phoenix to arrange for detour routes and maintain access to businesses and a school while Pinnacle Peak Road was closed. All of the on- and off-ramps at the Pinnacle Peak Road interchange remained open to traffic.

ADOT’s project to reconstruct the interchanges at Happy Valley and Pinnacle Peak roads started in November 2018 and is scheduled for completion by fall 2020.

The project is funded through the Maricopa Association of Governments’ Regional Transportation Plan approved by Maricopa County voters in 2004. Funding sources include a regional half-cent sales tax for transportation projects as well as the Phoenix region’s share of federal highway funds.
