The tunnel will be mainly aligned under Oneawa Hills, Beginning at Kailua Regional WWTP.
The first leg of boring will be beneath the north east side of Kaneohe Bay Drive passing under Aikahi Gardens through Halia Street (not below buildings).
From there, the alignment runs under the Kailua side of the H3 freeway and thru the center of Oneawa Hills.
For the last leg of boring the TBM will cross under Mokapu Boulevard and continue thru the hills with a slight curve until it reaches the conventionally mined portion of tunnel near the Kaneohe Regional WWPTF. The TBM will then be removed from the tunnel through a shaft at the Kaneohe Regional WWPTF.
