Beretania Street was closed in the westbound direction from Ward Avenue for about an hour today after a member of the public dropped off possible military ordnance at the Honolulu Police Department headquarters.

Beretania Street was closed sometime before 4 p.m. as HPD’s Specialized Services Division investigated. The roadway was opened at about 4:45 p.m.

Police evacuated the front portion of the Beretania Street headquarters building where the possible ordnance was dropped off.

City officials had advised drivers to avoid the Kinau Street off ramp from the H-1 Freeway due to congestion in the area.

The closure was unrelated to a memorial march for officers to be held later this evening that is also expected to close Beretania Street lanes.
