Two makai-bound lanes of Manoa Road were closed Wednesday morning as crews repaired a water main.
The 8-inch main break was reported Tuesday evening between Lanihuli Drive and Ahualani Place.
Crews worked through the night to restore water service to the 11 affected customers by 8 a.m. Wednesday.
Drivers were advised to take alternate routes to exit Manoa Valley Wednesday morning.
The road was repaired and fully reopened by 12:20 p.m.
