I've now mapped almost all the roads in the patch I have been working on, having done a stack more roads around the Ynstawe area. My Sunday afternoon stroll around the estate became unexpectedly long when I discovered the very pleasant footpath along the Clydach river and followed it all the way up to the Cwm Clydach nature reserve.

There are still quite a few little footpaths to do, but I probably won't do those at the moment - I think mapping the roads is a more productive use of time for now. However, I must walk along the Swansea Canal tow path at some point and map it. I've noticed that Google Maps gets it *completely* wrong, showing the canal joining the Clydach river - in reality the canal crosses the river as an aquaduct and continues a for few hundred metres South, whilst the river joins the Tawe just on the South-East side of the aquaduct.

I haven't quite worked out the best way to tag aquaducts though - setting waterway=aquaduct seems a bit silly since it doesn't let you specify the sort of waterway being carried (i.e. canal), so for now I have settled on bridge=yes instead.
