Crews are trying to figure out why a portion of Kailua Road gave in creating a sinkhole overnight.
It was discovered around 12:30 a.m. near Oneawa Street. Kailua Road is closed in both directions between Hamakua Drive and Oneawa Street.
The hole, at one point, measured about 10-feet-by-10-feet. The original sinkhole was only about 1-foot-long.
Police say there were no injuries and no buildings are in danger.
