Road repairs have been completed at the site of a water main break on Kailua Road and all traffic lanes between Aumoe Road and South Kainalu Drive have been reopened.

Board of Water Supply crews completed backfilling the trench and repaving the roadway at 197 Kailua Road at around 3:45 p.m. Friday.

The 10-inch, 70-year-old water main broke at 5:15 p.m. Thursday, a BWS spokesman said.  About 40 customers lost water service until repairs to the main were completed at 1:30 a.m. Friday.

Water intruded into three to six houses and garages, though not substantially, and threatened another dozen homes, said Fire Capt. Terry Seelig.
