Due to a police investigation, I-10 was closed near Cortaro

MARANA, Ariz. (KGUN) — We're working to learn more about the heavy police presence on I-10 that's causing a traffic jam for commuters this morning.

At this time, we know that the Department of Public Safety is working with the Phoenix Police Department on an investigation on eastbound I-10 near Cortaro.

DPS tells us all eastbound lanes and access roads are closed near the investigation. Our traffic map also shows a major traffic jam for those heading west.

We don't know when the road will reopen.

Our Blake Phillips is currently on site and is working to find out what is happening. We also reached out to Phoenix police to learn more about what brought them to the Marana area.

Stay with KGUN9 for updates throughout the morning.
