City officials said Thursday it will take two weeks to repair a section of Ala Moana Beach Park Drive where a large sinkhole has been blocking the Ewa entrance to Ala Moana Regional Park since Tuesday afternoon.

A contractor and city crews will work seven days a week to repair multiple holes in 48-inch pipes below the road near the Ewa entrance at Ala Moana Boulevard and Kamakee Street, the city said in a news release.

The pipes are overflow conduits between the park lagoon and Kewalo Basin Harbor.

Until the road is reopened, vehicular access to Oahu’s most popular beach park will be limited to the Diamond Head entrance at Ala Moana Boulevard and Atkinson Drive.

Pedestrians and bicyclists will be allowed to enter the park through the Ewa entrance.

City officials say the damaged pipes caused the sinkhole, and repairs can take place only during low tide.

An emergency contract for repair of the drain line and driveway was issued to the firm Site Engineering for $125,000. Staff from the Department of Design and Construction completed the engineering design in-house, city officials said.

To ease traffic backup exiting the park during the Ewa-entrance closure, the Department of Transportation Services has modified traffic signals at Atkinson Drive to allow for a green light of 60 seconds for exiting vehicles. Normally, the light stays green for 20 seconds, the city said.

During weekend peak traffic hours, special-duty police officers will direct traffic.

The park will continue to be open from 4 a.m. to 10 p.m. daily.
