A PNG contains either 3 (RGB) or 4 (RGBA) channels, so "exporting the alpha channel" is part of exporting the image.
Unless your problem is that you are forcing the export to 8bpc RGB and not to 8bpc RGBA thus explicitly dropping the alpha channel. if you export with automatic pixelformat, you should also get 8pbc RGBA if your layer has an alpha channel.
thank you
it was choosing the 8bit rgb that was causing the issueHow would I be able to remove the old road off the red, green channel? I've found post that shows me how to apply a layer mask so I can put my new roads on.

either that or figure out why my current alpha file doesn't have the transparency over the top for it to work
