Enbridge has begun their Line 5 Segment Relocation project that intersects the NCT in the Mellen / Copper Falls to Gurney area (MM 171.25, MM 185-186.5, and MM 200.5-202.5; map: https://arcg.is/bPuSX2). They have coordinated with the NCTA to minimize impacts to the NCT and NCT hikers.
Enbridge has already cleared trees on the pipeline corridor and expects to start construction activity beginning this May (2026). NCT users can expect heavy construction traffic on Vogues Road, which is also an access road for reaching the NCT. Temporary NCT detours / closures may be possible as blasting will be used near MM 186.25.
The NCT in the Wren Falls area is best accessed via Casey Sag Road (off of Hwy 77) to Sullivan Forest Road to Wren Falls Road (map: https://arcgis.is/1aKzWv0).
