East-West Tie Transmission Line Project

The Project is an approximately 450 kilometer, double-circuit, 230-kilovolt transmission line from the Wawa Transformer Station (TS) to the Lakehead TS in the Municipality of Shuniah, near Thunder Bay, Ontario, with a connection approximately mid-way at the Marathon TS.

Construction of the project began in September 2019 and is expected to be complete by the end of 2021.

This vital $777-million energy infrastructure project is one of the largest investments into the Northwest’s electricity system in decades and will provide access to energy to support new economic growth in the region for years to come.

The Detailed Project Plan (DPP) for Nimoosh Provincial Park is now available. This DPP, along with all the workfront DPPs and available parks and conservation reserve DPPs, is available for viewing and download on the Public Record Documents page.

The construction schedule by workfront is available below. Please note, construction start dates for workfronts 2 through 11 have changed from what was anticipated in early September 2019. The schedule continues to be subject to change and any future updates will be posted on this site.

The project is now on Facebook! Join the “NextBridge East-West Tie Line Project” Facebook group for additional project updates and information on activities along the project right of way.

Construction officially began on September 25, 2019. NextBridge was pleased to celebrate this major milestone with project partners and supporters at a groundbreaking ceremony on October 2 in Shuniah, Ontario. Read more about the groundbreaking here.

Project Map and Construction Timing

Project construction is divided into 11 workfronts. Construction will generally begin at the west end of workfronts 1 and 7 and progress in an easterly direction. Four worker camps are also anticipated for the project to house construction staff. Construction began on workfront 1 the week of September 23, 2019. Construction will commence in other workfronts as permits are acquired. The current anticipated construction schedule is shown below. Given the complexity of the project, this schedule may change, and any updates will be posted here.

Anticipated Construction Starts by Workfront
September 2019 Workfront 1
November 2019 Workfront 7
December 2019 Workfronts 2, 4, 5, 6, 8, 10, and 11
August 2020 Workfronts 3 and 9

Construction is expected to be complete by the end of 2021.

Detailed Project Plans, or DPPs, are being developed for each workfront and for the overall project. DPPs are bring posted in the Public Record Documents page as they are finalized. These DPP’s are the detailed plans of “how”, “where” and “when” we plan to construct that make up our final permitting approvals for the project construction and may be updated from time to time.

Detailed mapping of the project right of way is available here.

How do you build a transmission line? The Construction Process

Construction of a high-voltage transmission line is similar to highway construction. It moves forward in phases and involves moving along the corridor as construction progresses. During construction in your community, you can expect to see the following steps take place.

Step 1 Right of Way Clearing and Access Road Construction
  • May consist of logging, mulching and clearing of debris
Step 2 Geomatics & Surveys
  • Survey crews stake or flag locations for the towers using predetermined GPS coordinates
  • Crews also determine if the planned tower location is actually viable for installation
Step 3 Material Delivery
  • Materials are stored and sorted in material yards offsite and will be delivered to site as they are required
Step 4 Foundations and Anchors for Two Types of Towers
  • Self-Supporting Towers – require foundations for each leg of the towers
  • Guyed-Y Towers – require one foundation and multiple anchors for the guy wires
Step 5 Tower Assembly
  • Steel towers are typically assembled on the ground or in a laydown yard near each tower site
Step 6 Tower Erection
  • Towers are set into place with cranes or helicopters
  • Some towers are erected as one piece, while others are done in multiple pieces
  • Towers are then secured to the foundation
Step 7 Conductor Stringing
  • Stringing refers to hanging and fastening the conductor wire to the towers, this can be done with cranes or helicopters
Step 8 Reclamation
  • After completing construction in an area, the sites will be returned as close as possible to their original ground conditions

Safety is our Top Priority – How do you stay safe during construction?

At NextBridge, the safety of community members, our employees and the environment is our top priority so we must all work together to prevent injury. For your safety and that of workers, during construction please:

  • Respect all speed and direction signs in construction zones
  • Obey signs and instructions provided by flag people
  • Watch out for increased construction vehicle activity on local roads and highways
  • Obey signs at construction sites, including “no trespassing” signs on the rights of way and at laydown yards
  • Respect temporary road and trail closures

Have a question? Want to let NextBridge know about an issue? We want to hear from you.

NextBridge is committed to being a strong community partner and we want to hear from you. During construction we will have a Community Liaison on staff to ensure we are accessible to deal with any potential inquiries or issues so we can proactively address issues and deal with inquiries as they arise to avoid formal complaints.

If you have questions about the project or if you have concerns, including unsafe conditions or activities, please contact the project email or hotline:
