PGE starts construction on new substation and upgraded power lines on SW Naito Parkway

On September 5, Portland General Electric started work along SW Naito Parkway and SW First Avenue to install a new substation and upgrade power lines in downtown Portland. The project builds new infrastructure to support Portland’s growth and continue to help the the downtown core thrive.

These improvements include replacing 60-year-old equipment by adding the new Marquam Substation and upgrading the underground power lines along SW Naito Parkway and SW First Avenue that serve Portland’s downtown and South Waterfront.

The new substation and power lines will:
  • Make electric service even more reliable.
  • Strengthen the downtown grid, making it more resilient.
  • Replace old equipment with new, smarter technologies.

They are working with the city of Portland and local businesses to minimize the disruption of this construction.

What to expect

Construction began September 5, and will likely last through fall 2018, and will involve digging into streets and sidewalks. These will get restored as quickly as possible.

During construction, crews will be working block by block in the project area to help minimize disruption to traffic and local businesses.

Drivers should expect lane closures between one and two blocks long. The lane closures will begin on the south end of SW Naito and SW First, and then move northward as the construction progresses. There will be delays, so drivers may want to use alternative routes to and from downtown.

Cyclists should expect to slow down and adjust their routes as alternate bike lanes will be provided in the construction areas.

Pedestrians should expect sidewalk closures in the construction areas. This will begin on the south end, near I-405 and move north as construction progresses.
