MnDot was forced to close two eastbound lanes of I-494 under the Penn Avenue bridge Thursday afternoon while crews repaired a buckle in the pavement.

"It's that time of year when heat, combined with moisture in the air and all the other factors on concrete pavement conspire to concrete to fail," MnDOT's Kent Barnard tells MPR.

The metro is experiencing low to mid 90-degree temperatures with dew points around 70 degrees, making it feel like 100 degrees at times Thursday, according to KARE 11.

Although it's not a very good shot, KSTP captured some video from MnDOT's traffic camera.
