State road crews will be keeping a close eye on the hillside along the Pali Highway due to a small mudslide.
The mudslide was reported shortly before 4:30 p.m. Monday.
The right lane in the Kailua-bound direction of Pali Highway was forced to closed after a mudslide just outside the second tunnel.
The lane has been reopened at about 8:30 p.m.
Crews on the scene say the mudslide itself was small, and was behind the concrete barriers.
The barriers stopped most of it from getting into the lanes of traffic.
