A critical mo-ped crash closed one lane of Isenberg Street tonight in Moiliili, police said.

The mo-ped and a vehicle collided at 7:33 p.m. near King and Isenberg streets, police said. One mauka-bound lane of Isenberg Street is closed at King Street.

Paramedics took a man who appeared to be in his 40s to the hospital in critical condition, said Bryan Cheplic, spokesman for the Honolulu Emergency Services Department.

It appears the vehicle hit the man as he was driving the mo-ped, Cheplic said.

Police advised motorists to expect delays in the area. It is unknown how long the investigation will take.
