This schedule is expected to continue through Aug. 31 in order to complete repaving of all westbound lanes toward the Funston Road overpass.

During the full closure, westbound motorists will be detoured via the Middle Street off-ramp (Exit 19A) from the westbound H-201 Moanalua Freeway to the Fort Shafter/Kaua Street on-ramp to re-enter the H-201 Moanalua Freeway as shown above.
