HDOT Sets New 15-35 MPH Speed Limits on Kekūanāoʻa Street Near Hilo

The Hawaiʻi Department of Transportation revised posted speed limits on Kekūanāoʻa Street (Airport Road) near Hilo International Airport, instituting a range of 15 mph to 35 mph across different segments to enhance safety and keep traffic moving efficiently around the terminal.

Under HDOT guidance, the terminal area is now posted at 15 mph. Approaching the terminal, speed limits will vary, with some approach segments increased to 35 mph. Specifically, on approach the limit changes from 25 mph to 35 mph after the first crossing with Kekūanāoʻa Place, then returns to 25 mph after the second crossing. Exiting the terminal area, limits will step from 15 mph up to 25 mph. The new limits were to take effect once crews installed the new signage; crews were scheduled to erect signs that week.

For Hilo motorists, rental car drivers, shuttle operators and airport employees, the changes are intended to reduce speed variability and clarify expectations along the access road. Slower terminal speeds prioritize pedestrians, baggage handlers and curbside activity, while the higher approach speeds aim to keep inbound and outbound traffic from backing up onto surrounding streets. HDOT reminded motorists to drive with aloha and obey all posted speed limits.

The adjustments respond to safety concerns common to airport corridors: frequent vehicle merges, pedestrian crossings, loading and unloading zones, and the mix of local and visitor drivers unfamiliar with lane patterns. For kamaʻāina who travel Airport Road regularly, the stepped speed scheme should be visible once signage is in place; for visitors, the clearer posted limits should make navigation more predictable.

Installation of the signs required crews working in the roadway, and drivers can expect to encounter workers while crews complete the changes. The department’s installation timetable indicated the limits would not be enforceable until signage was up, so compliance depends on the visible postings as well as community adherence to the new rules.

As the gateway to Hilo, Kekūanāoʻa Street serves both practical and cultural roles: it is a place where visitors catch their first glimpse of the island and where locals move between home, work and services. The revised limits aim to respect that dual role by balancing safety for people on foot and efficiency for vehicles. Readers should look for the new signs when driving to or from Hilo International Airport, follow the posted limits, and allow extra time if crews are still installing signage.
