City officials plan to start roadwork on multiple residential and side streets in Nanakuli on Monday as part of Mayor Kirk Caldwell’s islandwide repaving initiative.

The work will span 42 miles of roadway and is expected to be completed within a year.

City Councilwoman Kymberly Pine, who represents the Leeward Coast, said the project is needed because some Nanakuli roads have not been repaved in decades, adding that “some people are really going to have real relief from very bad roads.” She said residents were sent letters with information about the project as well as contact information if any problems arise.

The project includes pavement resurfacing, reconstructing some concrete curbs and gutters, adjusting utility manhole frames and installing pavement markers. Crews will also be removing trees identified as diseased or those that have damaged sidewalks and curbs, as well as trimming canopies and pruning roots by a certified arborist. The $10.4 million contract was awarded to Grace Pacific LLC.

Crews will work Monday to Friday from 8:30 a.m. to 3:30 p.m. with possible weekend work. Residents are advised to anticipate delays due to detours and road closures and to allow for extra travel time through the work areas. Local traffic, deliveries and trash collection are permitted during construction. For questions on traffic management, contact Construction Management and Engineering LLC at 829-1902.

No work is planned for Farrington Highway, which is under the state’s jurisdiction, and crews do not anticipate any closures on the highway, according to Construction Management. Crews will also be posting signs alerting motorists to closures and detours and will be assisted by special duty police officers.

Caldwell launched the five-year islandwide initiative in 2013 to repave 1,500 lane miles of city roads that were in substandard condition. The city has since repaved more than 1,130 miles, according to a city news release.

In March, city officials announced a plan to repave 113 lane miles of city streets and roads along the Waianae Coast, beginning in Waianae Valley and later moving to Nanakuli and Maili.
