I-17

Work to build a new, larger Interstate 17 bridge over Central Avenue south of downtown Phoenix is now underway as ADOT and partner agencies look ahead to improvements beyond the freeway itself. But the progress also means drivers should consider using alternate routes, including Interstate 10, while the bridge reconstruction requires I-17 lane closures.

PHOENIX – A section of Interstate 17 south of downtown Phoenix will be restricted starting this weekend through fall 2021 for a freeway bridge replacement project.

The Arizona Department of Transportation is set to begin a $13.5 million project to improve the I-17 bridge over Central Avenue.

The existing bridge, which first opened to traffic in 1962, will be replaced by a modern structure with increased clearance for commercial trucks traveling beneath it as well as Valley Metro's future Central Avenue light rail line.

Interstate 17 is a great highway, but if it only runs between Phoenix and Flagstaff, why is it called an interstate?

PHOENIX – The Arizona Department of Transportation is accelerating a project to widen and improve the Interstate 17 bridge over McConnell Drive entering Flagstaff by closing McConnell Drive until early May, followed by other restrictions through mid-August.

McConnell Drive is scheduled to be closed around the clock from Monday, April 13, through Friday, May 1. Beginning Saturday, May 2, McConnell Drive is scheduled to be closed between 5 a.m. and 7 p.m. daily through Sunday, May 31, while crews work on the next phase of the project.
