Days of high heat lead to buckling of I-380 pavement in Iowa
CEDAR RAPIDS, Iowa (AP) — Iowa roads officials say high outdoor temperatures are to blame for the buckling of a large section of pavement along Interstate 380 in Cedar Rapids.
Television station KCRG says the Iowa Department of Transportation was called around 6:30 p.m. Thursday after pavement on the inside lane of northbound I-380 heaved upward.
Some employees said it was the largest pavement heave they’ve ever seen. Officials estimate the pavement buckled about 14 inches in the center of the heave.
The Iowa State Patrol says five vehicles drove over the buckled pavement before troopers could shut down the lane. Officials say there was no visible damage to any of the vehicles and no injuries were reported.
