Huntsville Police are investigating a crash that happened along Interstate 565 Monday morning.
Police said the crash happened at the Mooresville Road Exit just before 6:30 a.m. The interstate was backed up past the I-65 interchange for over an hour. One driver said it all started when a driver rear-ended another, which caused a chain reaction.
At least three cars and a semi-truck that smashed into the barrier were involved. Police have not said if there were any injuries.
