Over the next five months, portions of three Eastside collector roads will be reconstructed and resurfaced — Haua‘ala, Mailihuna and Olohēna.

In addition, ancillary work will be performed including shoulder improvements, striping, and the installation of traffic signs and pavement markings.

For Haua‘ala and Mailihuna roads, the project will extend from Kūhiō Highway to Kawaihau Road, and on Olohēna, the work will span from Malu to Ka‘apuni Road.

Work hours are Monday to Friday from 8 a.m. to 3:30 p.m. with allowances for peak school traffic.

Motorists are advised to allow extra time to get to their destinations and to follow all traffic control devices.

The $2.5 million project is being funded through an 80/20 matching grant from the Federal Highways Administration with FHWA providing $2 million and the county’s share being $500,000.

The project will follow the standards set by the American Association of State Highway and Transportation Officials (AASHTO) in their Guide for Design Pavement Structures.

Where potholes or severe cracking from structural failure is occurring, the foundation will be rebuilt with asphalt treated base (ATB).

In other areas, the cold plane process will be used to strip old layers of asphalt, which will prevent the road course from rising and the shoulders from becoming uneven. Additionally, severely eroded shoulders will be backfilled to meet the roadway elevation.
