HONOLULU – The City and County of Honolulu’s Department of Design and Construction announces updated traffic modifications for the North Kalāheo Avenue Bridge rehabilitation project beginning Monday, May 18, 2026 in response to community feedback as the necessary bridge rehabilitation project continues.

Monday through Thursday, from 7:30 a.m. to 5:30 p.m., and Fridays from 7:30 a.m. to 3:30 p.m., the bridge will be open to contraflow in both directions. On Monday through Thursday, after 5:30 p.m., the bridge will be restricted to Kāne’ohe-bound traffic only; Kailua-bound motorists will be detoured until 7:30 a.m. the following morning.

The daytime contraflow will be in effect from May 18 to July 31, barring any unforeseen conditions. This is a change to the modifications announced on May 5, 2026. There will be no lane closures on weekends or holidays, and traffic will return to normal two-way travel. Traffic conditions will continue to be monitored for any necessary adjustments. Motorists are reminded to observe all traffic control devices, posted signs, and the directions of Special Duty Police Officers.
