Makaha Bridge Replacement project No. 3 and No. 3A


Farrington Highway, Replacement of Mākaha Bridge No. 3 & No. 3A
District of Waiʻanae, Island of Oʻahu, State of Hawaiʻi
Project No. BR-093-1(20)

Project information
The State of Hawaiʻi Department of Transportation (HDOT), Highways Division, is replacing Bridge No. 3 and No. 3A, two aging wood bridges with prefabricated steel bridges. This project is located in Mākaha in the Waiʻanae District on the island of Oʻahu. Bridge No. 3 and No. 3A are located along Farrington Highway near Kili Drive at mile marker 14.02 (No. 3) and mile marker 14.096 (No. 3A).

The purpose of the project is to improve the structural integrity, hydraulic openings, and stream channel improvements of Mākaha Bridge No. 3 & No. 3A. The bridges will ensure that residents west of the bridge sites will have continued safe access to the highway. The structures will include 11 foot travel lanes and 7.5 foot shoulders, improvements along two drainageways, relocation of bus facilities, guardrail upgrades, replacement of existing driveways, relocation of water and electrical utilities, and signage upgrades. The placement of the bridges will ensure that the structures will not preclude future realignment of Farrington Highway and will consider long term effects of climate change and sea level rise. Stream openings and other weather-resistant features of the Mākaha Bridge No. 3 and 3A replacements will remain within the 100-year storm level predictions.

The installation of Bridge 3 and 3A has been completed.

The 24-hour, single-lane closure on Farrington Highway (Route 93) at Mākaha Bridge No. 3, in place through Friday, March 22. Details here.

• Access for Emergency Medical Services will be available throughout the lane closure.
• Pedestrian access will be maintained.
• Mākaha Beach Park, Kea‘au Beach Park, Mākua Beach Park and Keawa‘ula Beach/Yokohama Bay will be open.
