Community leaders and county officials opened a 2.2-mile long stretch of the Mamalahoa Higway bypass Friday in Kona.
The long-awaited southern segment cost $27.9 million and is located midway between the shoreline and Mamalahoa Highway. The northern segment of the bypass starts at the southern edge of Keauhou and runs approximately 3.5 miles to the bottom of Halekii Street below Kealakekua's Kona Scenic subdivision.
This new southern segment extends the roadway, which the Hawaii County Council named Alii Drive, another 2.2 miles from Kealakekua to a new signalized intersection with Mamalahoa Highway in Napoopoo.
Completing the Mamalahoa Highway Bypass was one of Mayor Kenoi's priorities upon taking office in 2008.
A large portion of the South Kona community works in either North Kona or South Kohala and commutes daily along Mamalahoa Highway. The two-lane bypass gives motorists an alternate route between North and South Kona.
