So, I kind got ahead of myself several days ago, when I was tearing down segments of the trunk, to make room for the new belts. I forgot that THIS junction here is where I actually want to pull the new belts off, to the right, and I tore down a bit more than I needed to, on the left. So, we'll have to repair that, after building this junction.

Meanwhile, I need to work towards tearing down this short segment of trunk that the belts DO need to run on.

I figured the best way to figure out how far down the trunk I need to go is to build towards it from the opposite end. So I built some scaffolding in towards the coast, from out in the sea, and connected them up.

A little more power bypassing, and it was safe to tear down the trunk.

Belts are all laid in, from the junction where the Copper meets up with the Iron and Limestone, down to where the final junction will be.

And that's everything tidied back up, including all the bypasses removed and the unnecessary teardown rebuilt.
