The Iowa DOT says the latest heat wave is responsible for a large pavement heave on I-380.

According to the Iowa Department of Transportation, they were called at around 6:30 p.m. Thursday concerning a section of the inside lane of northbound I-380 near Center Point that had raised up.

A crew was sent out to clear away the damaged section and replace with new asphalt. Employees of the DOT say it was the largest pavement heave they had ever seen. The estimate the pavement raised up about 14 inches in the center of the heave.

The Iowa State Patrol and Linn County Sheriff's Office also responded. The Iowa State Patrol says five vehicles drove over the heave before they were able to get the lane shut down. They say there was no visible damage to any of the vehicles and no injuries were reported.

The Iowa State Patrol reminds drivers to call 9-1-1 immediately if they see issues with roadways that could cause damage to vehicles or injuries to drivers.
