An East Valley road is blocked after a semi-truck rolled over in a crash early Wednesday morning.

Maricopa County Sheriff’s deputies responded to the crash involving the semi-truck and another vehicle around 3:30 a.m. at Signal Butte Road and Broadway Road.

Three people were hospitalized with non-life-threatening injuries, according to the Maricopa County Sheriff’s Office.

Signal Butte Road is blocked in both directions due to the rolled semi in the roadway.

A power pole was downed in the crash, and SRP crews are working to restore power. It’s unclear how many customers are affected by the outage.

The cause of the crash is still under investigation.
