A five-mile stretch of Interstate 84 will be closed in both directions to rail and highway traffic overnight from 11 p.m. Saturday, July 13 to noon Sunday, July 14 for graffiti cleaning and trash removal between I-5 and I-205.

In addition to the I-84 closure in Sullivan’s Gulch, northbound Interstate 5 will be closed over the Marquam Bridge with traffic diverted onto northbound Interstate 405. Crews will take advantage of the overnight closure to carry out bridge maintenance activities. The Morrison Bridge and North Weidler Street ramps to northbound I-5 will remain open.

The coordinated effort by six agencies — ODOT, Union Pacific Railroad, TriMet, the Portland Bureau of Transportation, Metro and Multnomah County — will target one of the most visible parts of the Portland area and one particularly hard hit by graffiti and trash.

Upwards of 100 workers from the six agencies will join private contractors to remove trash and clean graffiti along the corridor, starting from west to east. All on-ramps leading to I-84 will be closed as well.

For real time traffic information during the closure, go to TripCheck.com. This work is weather dependent and the schedule may change.

As a detour, motorists should use I-205 or local roads to bypass the overnight closure. Travelers should plan ahead and expect delays in the area.

During the closure, Union Pacific may need to run a train on occasion through their corridor.

TriMet may need a couple of hours to resume MAX service once I-84 has reopened as crews will need to reenergize the system.

You can sign up now for service alerts to arrive by email or text by going to trimet.org/emailupdates.

All highway lanes will reopen by noon Sunday, July 14. MAX Blue, Green and Red Line trains will also be disrupted during the closure between the Gateway/NE 99th Ave Transit Center and NE 7th Ave to allow crews to access the right of way. Shuttle buses will serve closed stations during the disruption.
