Portland Water Bureau crews are responding to a water main break on St. Helens Road from Northwest 31st to 35th avenues.
To assess and repair the damaged water pipe, crews must shut down streets until early Sunday morning.
The main is a 16-inch pipe from 1913.
The traveling public is reminded to stay alert and use caution as traffic may suddenly slow or stop. To avoid traffic delays, motorists are encouraged to use alternate routes around the work site.
The Portland Water Bureau’s Maintenance & Construction crews are ready to respond to emergencies, including water main breaks, 24-hours a day, seven days a week. On average, crews respond to 200 main breaks a year.
