Strengthening the Energy Grid
New substation and upgraded power lines coming to downtown Portland
Beginning in fall 2017, we’ll be working along SW Naito Parkway and SW First Avenue
PGE is building new infrastructure to support Portland’s growth and continue to help the hub of our city 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.
We’re working with the City of Portland and local businesses to minimize the disruption of this construction.
What to expect
Construction begins September 2017 and is likely to last through fall 2018. It 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.
You can also expect:
- Flaggers to direct traffic and provide alternate bike lanes as needed.
- Some parking and loading restrictions near work areas for safety.
- Noise, vibration and dust from construction.
- Repairs following construction to improve road conditions.
- Work will be paused during City of Portland construction moratoriums.
Currently in construction or starting soon:
SW NAITO PARKWAY
Crews have completed recent work on the right-hand, northbound lane of SW Naito Parkway near Lincoln Street.
Crews also just completed digging a temporary trench across SW Naito Parkway.
All excavation is covered by temporary road patching. When the weather dries and the temperature warms, permanent concrete or asphalt will be placed.
SW FIRST AVENUE
Excavation on SW First Avenue between Sheridan and Lincoln Streets is nearly complete.
Work will now progress along SW First Avenue between Lincoln and Harrison Streets. This work will last until approximately Nov. 22. There will be a single right-hand lane closure for the duration, for all hours and all days of work. On the night of Nov. 20, both northbound lanes will be closed at 6 p.m. to install a vault. The lane is expected to reopen at 2 a.m.
Work will then resume after the Thanksgiving holiday on SW First Avenue between Harrison and Market Streets. This work is scheduled to last until 29. This work will block sidewalk access and parking spots on the east side of SW First Street. There will be a left-hand lane and a turn lane closure for the duration of this work. This closure will be for all hours and all days of work.
Future construction: TBD
As always, safety first
To help ensure everyone’s safety, all work areas will be well marked and surrounded by fencing.
You can do your part by staying away from all construction equipment, open trenches, electrical equipment and cables.
We appreciate your patience during these improvements.
