A sanitary sewer main replacement project on East 9th Street in The Dalles has been suspended after excavation had to be stopped due to a dig into underground utilities. The Dalles Public Works says the City had contacted the 811 Utility Notification Center to locate existing underground utilities and utilities were clearly marked. But the markings provided for an existing privately-owned fiber optic line were incorrect and City crews on Wednesday excavated into and damaged it. Work by a private contractor to complete an emergency repair of the damaged fiber optic line extended well into Wednesday night and have been completed. The City will be suspending work on the project on East 9th St west of Quinton Street while the City works with the private utility owners to resolve any potential conflicts. The trench will be filled and roads reopened for use by this coming weekend. After that, the City says work on the pipeline replacement project will not resume until it is confident that excavation can be done safely, without interrupting utility service.
