Part of Buckley Road buckled in the heat this weekend.
"Heat and concrete don't always mix," Arapahoe County wrote on its website. "A concrete panel on northbound Buckley Road buckled from the heat and will be undergoing emergency repairs."
Northbound Buckley Road is closed from Arapahoe Road to Peakview Avenue because of the buckled concrete.
Southbound Buckley Road is open in the area.
Arapahoe County said it hopes to reopen the road by late Monday afternoon.
