What you see in the RGB channels thumbnails is an indirect consequence of the layers contents.
You can't edit them directly, you have to edit the layers. If you want to remove your red road, you paint over it on the layer(s), where it appears. Don't put too much importance on the Channels display. There are a few tricks involving it, but by and large you can do all your editing without looking at it.
Notes: in you second image, you have deselected most channels.
Also, it is a lot easier for us if you add your pictures as forum attachments, because they appear in the text and we don't have to try to leated random names in your post to random images.
