10:30 a.m. update: Lanes at all three collision sites have cleared.

Traffic collisions in North Texas have caused main lane closures on multiple highways Friday morning, as storms rip through the area.

Interstate 35 at U.S. Highway 380 (University Drive) has two main lanes closed due to an accident. It’s unclear what occurred, but first responders and tow vehicles can be seen onsite, according to TxDOT cameras. 

Traffic is backed up for several miles.

On I-35W at Robson Ranch Road, traffic can be seen backed up for several miles headed northbound toward Denton. First responders cannot be seen onsite yet but have been alerted, according to TxDOT cameras. 

It is unclear what collision occurred. The right lane and right shoulder are closed.

Two eastbound lanes on Woodall Rodgers Freeway, in the tunnel under Klyde Warren Park, are closed due to an accident.

Although TxDOT cameras do not show active incidents in the tunnel, traffic can be seen backed up past the I-35E connecting point. 

First responders have been alerted and may be onsite, according to TxDOT cameras.

This is a developing story and will be updated.
