Starting Tuesday, crews from the Hawaiian Dredging Construction Company will convert Waimanu St. into a two-way street.

The mauka lane of Waimanu St. will be converted into a westbound lane with on-street parking.

Traffic signals will be modified on Waimanu at both Pensacola and Piikoi.

City officials say the change is expected to provide greater connectivity for the planned major rail transit station on Kona St., provide a direct eastbound and westbound connection between future rail stations in Kakaako and at Ala Moana Center, and eliminate congestion on Ala Moana Blvd.

The project is expected to be completed before Christmas this year, according to officials.

Waimanu St. between Pensacola and Piikoi streets is currently a four-lane, one-way, eastbound road.
