The Arizona Department of Transportation will close a section of Interstate-10 starting Thursday night.
Overnight closures of I-10 at 59th Avenue in west Phoenix are scheduled for Thursday and Sunday nights for work related to the Loop 202 South Mountain Freeway interchange.
The closures will begin at 11 p.m. and end at 5 a.m.
ADOT is advising drivers to allow extra travel time and consider alternate routes.
Additional closures will be scheduled over the next several weeks to allow crews to move equipment as work advances on bridge structures.
The South Mountain Freeway will open by late 2019.
