The state Department of Land and Natural Resources Division of State Parks says a pedestrian safety project inside the tunnel of the Diamond Head State Monument was delayed Thursday due to the weather.
Between 3 p.m. to 6 p.m., which are less busy hours at the park, all vehicle traffic in the Kahala Tunnel was going to be reduced to one lane, while the safety improvements was being installed.
The plan was that the pedestrian path through the tunnel would be widened, and flexible reflective bollards would be installed to delineate the pedestrian path. Modified lane markings was also going to be painted on the asphalt road, and signs posted in front of each entrance to the Kahala Tunnel.
Both pedestrian and vehicular traffic at Diamond Head State Monument has increased around 20 percent in the last year.
During the mornings, the morning peak visitor time at Diamond Head, pedestrians and vehicles create congestion in the Kahala Tunnel, which is the access point into Diamond Head crater.
Vehicle drivers are reminded that the speed limit through the Kahala Tunnel is 5 mph. The speed limit on the park entry road is 10 mph.
