Police investigating serious crash on I35 in Denton

The Denton Police Department is investigating a serious crash involving multiple vehicles in the northbound lanes of I35E near University Drive on the west side of town.
Multiple vehicles were involved in the crash with significant damage reported. At least two vehicles and one commercial truck are involved.
Police have not released details just yet, but reports indicate at least one person has sustained serious, potentially critical, injuries. There were multiple patients reported at the scene.
Only the left lane gets by. This has caused a significant backup on both northbound I35E and I35W just north of the split.
We will update when police released additional details. It is best to avoid this area.
