A busy East Valley freeway transition is blocked due to a rollover crash early Thursday morning.

Arizona Department of Public Safety (DPS) troopers were called to the Red Mountain Loop 202 eastbound transition ramp to the Loop 101 just before 6 a.m. for the reported crash.

Details about what led to the crash are still limited. A large truck could be seen rolled over on its side, as well as a white sedan with severe front-end damage.

DPS said injuries were reported in the crash, but the details of who was hurt are unclear. Arizona’s Family has a crew at the scene working to learn more information.
