Extra Credit is video series that examines topics related to history in the Thunder Bay District and exploring that history.

This episode, the ninth in sub-series on the former Kinghorn Subdivision, takes us north of Nipigon to the communities of Macdiarmid/Biinjitiwaabik Zaaging Anishinaabek, ON and the tunnel located nearby. The Macdiarmid or Jumbo’s Cove Tunnel was built circa 1911-1912 and is the longest rail tunnel in this part of the country and one of the longest tunnels in eastern Canada. With its unique concrete work and its length, it is certainly quite the place to visit.

Enjoy!
