I would recommend drawing a separate “way” for the highway. I
imagine that the route taken by vehicles or people walking is a
few meters off of the center of the waterway, and perhaps a little
straighter. If you are coarsest tracing the waterway and road,
then the two ways might share most of their nodes.<br>

I don't think you have used them. The ones I have used:<br>
The waterway will vary from one flow to the next by some meters -
they are sand bottoms. The rivers when flowing are 10s of metres
wide. <br>
Some flood in flatter areas.<br>
The road/track will change after a rain event by meters to make best
use of the changed topography. <br>
The are mostly sandy bottoms - meters wide. Take a look at the Todd
River in<br>

<br>
<br>
The way shown in OSM (or any map) is a guide. <br>
I would not take the trouble to offset one from the other, if it
were done then it is bound to be on the wrong side :)<br>
