Ninole Stream Bridge

Project Overview

The Central Federal Lands Highway Division of the Federal Highway Administration in cooperation with the Hawaii Department of Transportation is developing a project located on the Mamalahoa Highway, Route 11, at M.P 56.7, the Ninole Stream Bridge, on the Island of Hawaii. The Ninole Stream Bridge is located on the Mamalahoa Highway (Route 11) at mile post 56.7 and approximately 480 feet south of the Punaluu Road intersection, in the Kau District.

The project would improve the safety and reliability of the timber bridge, through rehabilitation or replacement, addressing bridge width, load capacity, bridge railing and transitions, and bridge approaches.

A Final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) has been prepared pursuant to HRS Chapter 343 (as amended), and Hawaii Administrative Rules Title 11, Chapter 200.
