Traffic Advisory: Sewer work to close N Interstate Ave near Broadway Bridge 7:30 a.m. to 2 p.m., Thursday April 21

(April 20, 2016) - The Portland Bureau of Transportation advises the traveling public that sewer repairs will require closures of N Interstate Avenue on Thursday, April 21 between NE Tillamook Street and the Veterans Memorial Coliseum.

Northbound Interstate Avenue will be closed from 7:30 a.m. to 2 p.m. Northbound bicycle and motor vehicle traffic will be detoured at N Larabee Avenue, through N Broadway, to rejoin N Interstate farther north.

Southbound Interstate Avenue will be closed between N Tillamook and N Thunderbird Way from 7:30 to 10 a.m. Southbound motor vehicle and bicycle traffic will be detoured to the Broadway Bridge ramp, then to Larabee Ave., rejoining N Interstate Ave, south of Broadway.

The work is required to inspect some sewer lines in southbound lanes and fix a small underground cavity in the northbound lane. PBOT has received complaints that motor vehicle drivers on northbound Interstate Avenue have been driving in the bike lane to avoid a steel plate set temporarily in the travel lane. Repairs on northbound Interstate Avenue should allow crews to replace the steel plate with asphalt.

The traveling public is advised to expect delays while repairs are being made and use alternative routes if possible. We ask the public to travel cautiously and observe all lane closures and directions from reader boards, signage and flaggers.

This work is weather-dependent and the schedule may change.


The Portland Bureau of Transportation (PBOT) is the steward of the City's transportation system, and a community partner in shaping a livable city. We plan, build, manage and maintain an effective and safe transportation system that provides access and mobility.
