Queen Kaahumanu Expressway speed limit is now 45 mph to Waikoloa Beach Drive

KONA – The Hawaii Department of Transportation (HDOT) is announcing that the speed limit on the Queen Kaahumanu Highway (Route 19) between mileposts 67 and 75.4 (near Kawaihae Road and near Waikoloa Beach Drive ) is now 45 mph. New speed limit signs were installed in early September and came into effect on Friday September 9, 2022.

Before, the speed limit along this corridor ranged from 55 mph to 45 mph. It was 55 mph between the highway’s intersection with Kawaihae Road and the north entrance to Waikoloa Beach Drive; then it increased to 45 mph to the south entrance of Waikoloa Beach Drive. The speed limit on Queen Kaahumanu between south of Waikoloa Beach Drive and Ellison Onizuka Kona Keahole International Airport (KOA) was 55 mph and 45 mph at the intersection leading to KOA.

Changing the speed limit to a constant speed of 45 mph was prompted by crash data, including one fatal crash, T-Crashes at the Mauna Lani Drive intersection reported near accidents and the presence of adjacent residences.

HDOT actively manages speed to improve safety on national roads using tactics such as speed limit signs, proper sizing, roundabouts and raised pedestrian crossings where appropriate. The probability of death increases dramatically with speed for all highway users. Implementing speed management and traffic calming can reduce serious injuries and fatalities on the roads while ensuring an efficient system.

HDOT appreciates all drivers who follow traffic control signs and help keep our roads safe.
