Two separate accidents involving semi-trucks seriously injured two men and closed two well-traveled roadways today.

At about 11:30 a.m., a traffic accident involving a container truck and an automobile seriously injured a man and temporarily closed Kunia Road near Schofield Barracks’ Lyman Gate this afternoon. City Emergency Medical Services officials said paramedics treated the driver of the car, a male in his 30s, and took him to a hospital in serious condition after “a semi-truck crashed on to his vehicle.”

Police closed Kunia Road in both directions from Lyman Gate to the Kunia Golf Course immediately after the accident, but at about 1 p.m. traffic was being contra-flowed near Kunia Village.

At about 12:35 p.m., paramedics treated the male driver of a semi-truck that overturned at the H-1 westbound Campbell off-ramp. The man, 55, was taken to a trauma hospital in serious condition.

Police said they closed the off-ramp due to an oil spill from the accident.

The off-ramp was reopened around 2:15 p.m.

Kunia road was reopened about 4 p.m.
