Hey there! For the portion along Main Street between Prior & National Avenue, I worked on a project at an adjacent building site where we had a BCOC & review with the BC Hydro.

This is from their Transmissions team:

"BC Hydro Underground Transmission Circuit 2L053 is installed under Main Street.  This section of 2L053 is a 230,000 volts, concrete duct bank installed, cable circuit that is approximately 4.3m west of the property line."

Our utility locators were also able to confirm the presence of the conduit under the road.

Similarly, we had projects near E2nd & Main, and along Prince Edward which had this same transmission conduit.

I think the BC Hydro maps might be out of date because we keep running into transmission lines where we don't expect them!
