Interstate 5 northbound will close between the Marquam and Fremont Bridges from 10 p.m. Friday, May 5 until as late as 4:30 a.m. Monday, May 8.

The closure is the third of four full directional closures of I-5 for Burnside Bridge repairs. ODOT will also complete paving and bridge repairs on I-5 between Broadway and the Fremont Bridge.

Travelers on I-5 northbound will take Interstate 405 northbound (exit 299B) across the Fremont Bridge to reach I-5 northbound.

The following on- and- off-ramps will close to keep travelers out of the work zone:

  • I-5 northbound Marquam Bridge. Detour: I-405 northbound to reach I-5 northbound; I-405 northbound to I-5 southbound to reach I-84 eastbound
  • I-5 northbound Broadway/North Williams on-ramp. Detour: On-ramp open north of North Going or North Alberta streets
  • I-405 southbound SW Fifth Avenue on-ramp. Detour: I-405 southbound SW Broadway on-ramp
  • Interstate 84 westbound off-ramp to I-5 northbound and Convention Center/Moda Center. Detour: I-5 southbound to I-405 northbound (exit 0) to reach I-5 north.
  • I-84 eastbound on-ramp from the Morrison Bridge. Detour: I-84 eastbound on-ramps at NE Grand at NE Everett.

The freeway closure will add to congestion so travelers should consider using other routes, including surface streets, or taking transit, depending on their travel plans.

A final weekend closure of I-5 north between the Marquam Bridge and North Broadway is scheduled from Friday night, May 12 to Monday morning, May 15.

Closing I-5 will allow contractor Hamilton Construction to perform concrete repairs underneath the Burnside Bridge, which spans lanes of the freeway. Areas of the concrete are degraded and at risk of falling on the freeway. This work is part of Multnomah County’s Burnside Bridge Maintenance project.
