I have pasted the relevant parts of each file below.  I have both (line
and symbol) on the same layer with I thought the same scales.

There is not enough information to answer this. Is the rest of the road
drawn using the same symbol definition, or is it a separate one (or even
a separate layer?). Normally the scale range for visibility is specified
for the whole layer, so if you are seeing this with data on the same
layer, it could be a bug.
