What’s there now:
18th Avenue runs from Diamond Head Road to Harding Avenue in Kaimuki. Along its mauka side, 18th Avenue is primarily residential while on its makai side 18th Avenue cuts between Kapiolani Community College, Kaimuki Middle School, and Diamond Head Memorial Park. The avenue’s speed limit is set to twenty-five miles per hour along its length. Bus stops, pedestrian crossings, and bike route signage designate 18th Avenue as a multi-modal road. Though narrow on its residential end, a parking ban on the Kapiolani Community College side of 18th Avenue ensures very wide lanes of travel. Outside of the bike route signage, there is currently no bike infrastructure on 18th Avenue.
What the Oahu Bike Plan calls for:
The Oahu Bike Plan calls for 0.33 miles of bike lanes to be installed on 18th Avenue from Diamond Head Road to Kilauea Avenue. The lanes would serve students headed to the nearby schools, allowing them to travel in protected bikeways without having to make the steep climb up Kilauea Avenue between 18th and Makapuu Avenue. The lanes would connect to planned bikeways on Diamond Head Road and Kilauea Avenue and take advantage of the generous width of 18th Avenue. The Oahu Bike Plan designates 18th Avenue as a priority one and short-range implementation project.
What’s being done:
The Department of Transportation Services has tentative plans to add bike lanes to 18th Avenue.
