Rose Quarter Underground: Looking at conditions from the bottom up

Pavement Exploration Work Starts in May

Crews are planning pavement exploration work in the I-5 Rose Quarter Improvement Project area starting in early May and continuing until late May. The work will provide information about the existing pavement condition of local streets to inform the multimodal design of the I-5 Rose Quarter Improvement Project.

What you will see and hear

The pavement explorations will be conducted by machine or hand and will involve holes ranging from 2 feet wide and 3 feet deep to 8 inches wide and 10 feet deep and will be backfilled within 24 hours and covered when not in use. You may hear some noise while crews work nearby, but activities will be no louder than typical traffic noises.

Here’s what you can expect from the pavement exploration work:

  • Work dates: May 4 – late May
  • Daytime work: Mon-Fri, 8 a.m. to 5 p.m.
  • Nighttime work: Mon-Sat, 8 p.m. to 5 a.m.
  • Temporary nighttime closures and detours for people walking, biking, rolling, and driving

Visit the ODOT’s Weekly Construction Update and visit TripCheckimage linked to trip check website for details on specific closures and detours – updates will be posted regularly until pavement exploration is complete.

Utility Mapping and Soil Sampling Coming this Summer

Underground utility mapping to start in June

Underground utility mapping and investigation work is scheduled to begin in June and continue through December in the project area. The purpose of this work is to collect and record the locations of underground utilities. This critical information is used to inform design and construction planning. Field work will primarily take place with short traffic impacts and little noise.

Here’s what you can expect from the utility mapping work:

  • Work dates: June through December
  • Daytime work: Mon-Fri, 8 a.m. to 5 p.m.
  • Nighttime work: Mon-Sat, 8 p.m. to 5 a.m.
  • Temporary closures and detours for people walking, biking, rolling, and driving

Soil sampling on and near I-5 scheduled to start in July

Crews are expected to collect soil samples in the Rose Quarter area starting in July and continuing until November. Soil sampling will occur on and near I-5, including some locations in the Willamette River. This work won’t impact river water quality. The soil sampling will ensure the I-5 Rose Quarter Improvement Project team develops designs that are appropriate for local soil conditions. More details on the soil sampling locations will be available on the project website as the schedule is developed.

What you will see and hear

Soil sampling will be conducted by heavy machinery and will involve holes approximately 8 to 12 inches wide and up to 120 feet deep. They will be backfilled within approximately two weeks of sampling and will be covered while not in use. You may hear some noise while crews work nearby, but activities will be no louder than typical traffic noises.

Here’s what you can expect from the soil sampling work:

  • Work dates: July through November
  • Daytime work: Mon-Fri, 8 a.m. to 5 p.m.
  • Nighttime work: Mon-Sat, 8 p.m. to 5 a.m.
  • Temporary closures and detours for people walking, biking, rolling, and driving
