A traffic signal at Fort Weaver Road and Keaunui Drive, near the entrance to the Hawai'i Prince Golf Course in 'Ewa Beach, is expected to go into service today, city and state transportation officials said yesterday.

Transportation officials said motorists should expect the signal to be activated sometime after peak morning and before peak evening traffic hours along the oft-congested Fort Weaver Road.

The signal is part of a $4.3 million project, which includes turnout lanes and other improvements at the intersection. It was completed by Gentry Hawaii as required by a traffic study done as a condition of a zoning approval it received from the Honolulu City Council in 2004.

The Keaunui intersection is just south of the planned widening of Fort Weaver Road to six lanes, scheduled to get under way this summer.

The opening of the intersection also allows the main entryway to the Hawai'i Prince Golf Course directly off the east side of Fort Weaver Road to be used again. Visitors have had to take a detour to the facility in recent months.

An additional 2,600-foot extension of Keaunui to the west, between Fort Weaver Road and Kapolei Parkway, is to open to the public in mid- to late July.
