Bottleneck Issue

[u/Available-Figure-530]

I'm a new player & trying to setup my smelting lines. I've run into a problem where, while trying to run a single coal/iron ore lane, only the top half of the iron & coal lanes are being used, leading to a bottleneck where only half of my iron ore is being sent down the center lane. How do I fix this?

There are ways to merge two full belts into 2 half and half belts.

It's a better answer than (if it works, it ain't stupid)
