Approximately 34 customers, 33 homes and one school, were without water. A water wagon was positioned near the break site to provide an alternative water source for the affected customers.
By 10 a.m., repairs were completed and water service was restored to all affected customers.
The road was closed just before 12:30 a.m. Wednesday.
All lanes were reopened by 2 p.m.
