The northbound lanes of I-35E were closed Friday morning in Lewisville after police officers exchanged gunshots with the suspect accused of killing a Dallas police officer late Thursday.

Police diverted all northbound traffic off the highway onto Highway 121 Business, causing a major backup. All lanes of northbound I-35E were impacted by the closure, including the express lanes. By 7:20 a.m., all lanes reopened.

The scene in Lewisville is about 40 miles from where two DPD officers responding to a distress call found an officer shot inside his patrol vehicle. The suspect exchanged fire with the two officers before driving off.

Officers chased the suspect to Lewisville, where Dallas police said the suspect got out of the vehicle with a “long gun” before officers shot at the suspect, killing the suspect. 

The highway was closed for around seven hours.
