<div>Keepright appears to think that bridges without a layer tag imply layer=1. Whereas I'd assumed in my tagging that layer=0 unless stated. Is this to match what renderers do? I would rather they didn't, because making the waterways layer=-1 seems to work most of the time, and I'd prefer to avoid adding layer=0 to the bridges as well.</div>

<div>I suspect Keepright also has a habit of inferring layer=1 on ways that connect to a bridge, which is a bit naughty if it does, though I may be wrong (obviously I am comparing the last keepright version of the data with the current status in Potlatch, so there's ample scope for confusion).</div>
