MONTH LONG RAMP CLOSURE: Capitol Highway
on-ramp to I-5 south will close for 35 days beginning midnight on Thursday, September 9

The Capitol Highway on-ramp to I-5 south will close beginning at 12:01 a.m. on Thursday, September 9. This means the ramp will be closed for the Thursday morning commute. The ramp will be closed for 35 days so workers can replace the concrete bridge deck and install new ramp joints and bridge rails. Travelers should follow posted detours and expect traffic delays and commute impacts.

Traffic impacts:

  • September 9 - October 14, 2021: Full 24/7 closure from 12:01 a.m. Thursday, September 9 to 5 a.m. Wednesday, October 14. (Find detour map and turn-by-turn directions here.)
  • 24/7 right lane closure on southbound SW Barbur Blvd. approaching Capitol Highway during the ramp closure.

All closures are subject to change and weather dependent. Please visit bit.ly/swi-5repair for the current closure information during construction or visit TripCheck.com for 24/7 traffic impacts in the Portland metro region.

About the Project

ODOT is repairing three on-ramps to Interstate 5 in SW Portland beginning in July 2021. We are also currently designing improvements to I-5 over SW 26th Avenue to begin in 2023. These structural improvements will maintain and extend the life of our roadway system and give travelers a smoother ride.

Ramp improvements this year include:

SW Multnomah Blvd on-ramp to I-5 north (now complete)

  • New concrete bridge surface.
  • New ramp joints.
  • New fencing and rail on both sides of the ramp.

Capitol Highway on-ramp to I-5 south:

  • New concrete bridge surface.
  • New ramp joints.
  • New bridge rail.

SW Barbur Blvd on-ramp to I-5 north:

  • Remove old paint and repaint steel bridge structure.
  • Replace bolts as needed.

OTHER TRAFFIC IMPACTS FOR THIS PROJECT

  • Nighttime single and double lane closures on I-5 north and south.
  • Nighttime closures of area on-ramps to I-5 north and south.
  • One full weekend closure of the Multnomah Blvd. on-ramp to I-5 north from July 16-19, 2021. (now complete)
  • Nighttime or daytime single lane closures on SW Multnomah Blvd. over I-5.
  • Nighttime single lane closures on SW Barbur Blvd. over I-5.

 

NOISE IMPACTS DURING CONSTRUCTION
