Portland Water Bureau crews are responding to a water main break on Southwest Naito Parkway, between Market and Harrison streets.
To assess and repair the damaged water pipe, traffic is confined to one lane in each direction on Southwest Naito Parkway between Market and Harrison streets through the Monday evening commute.
The pipe is a 16-size-inch cast iron pipe from 1959.
Four connections on Naito Parkway (three irrigation-only lines) may be out of service while the main is repaired.
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.
