Extreme heat causes road buckling near Lansing
Temperatures that topped 90 degrees over the weekend caused a section of highway outside Lansing to close twice when the road buckled.
Michigan Department of Transportation crews broke up concrete Sunday along northbound I-69 in Charlotte in Eaton County and filled gaps with quick-drying asphalt.
In extreme heat concrete isn't able to expand, so it starts to break up, MDOT told the Lansing State Journal.
Road buckling also closed southbound lanes of I-69 in the same location on Saturday night.
