Moanalua Freeway: Repairs to a Contractor-Damaged 42-Inch Transmission Main

One lane closed H-201 Moanalua West-Bound

TUESDAY, JUNE 22, 2021, 4:00 AM -- BWS crews continue to work on repair of a damaged 42-inch transmission water main on Moanalua Fwy., west-bound, near the Fort Shafter/Ahua Street off-ramp.

The Fort Shafter/Ahua St. off-ramp from H-201 is closed.

The Fort Shafter on-ramp to the H-201 Moanalua Fwy. from Kaua St. is presently closed. Motorists may continue on Kaua St. to merge onto H-201 at Moanalua Gardens.

One far-right lane of H-201 West Moanalua Fwy. is closed. as of 4:00 a.m.

The following traffic control measures will be in place until the transmission main and roadway can be fully repaired:

  • Expect 24/7 lane closures on the Moanalua Freeway from the H-1 Freeway split until the Fort Shafter on-ramp in the west-bound direction.
  • Weekday closure of one right west-bound lane from 4:00 a.m. – 10:00 p.m.
  • From 10:00 p.m. – 4:00 a.m., weekday closure of two right-hand west-bound lanes from the H‐1 split.
  • There will be signage and cones to direct drivers.
  • The Fort Shafter/Ahua St. exit will remain closed 24/7 until repairs are completed.

Please be advised that street lights on Moanalua Freeway from the Middle St. overpass to the Fort Shafter on-ramp are inoperable during the repair. Please drive with caution.

Motorists are strongly advised to avoid the area by using Nimitz Hwy. or the Airport Viaduct as an alternate travel route. The City and County of Honolulu, Department of Transportation Services is monitoring traffic on nearby surface streets and will adjust traffic signal timing to optimize flow of traffic.

Due to the size of the water main and extent of the repair, this work and the resulting lane closures will remain in effect through the week. The BWS continues to coordinate with other agencies to minimize impact to motorists.

    When will service be restored?
    BWS crews work to restore water service as quickly and as safely as possible. It is difficult to estimate when service can be restored, however, because we may need to address unforeseen issues and need to make water system adjustments before restoring service.
    The road is clear. Why isn't my water back on?
    For some repaired mains, especially along coastal areas or near streams, additional water quality testing may be necessary. This process can take up to 24 hours to complete. During that time, customers affected by the break, will typically have access to water wagons until testing is finished.
