                    <div>Hi Richard,<br>
                      <br>
                    </div>
                    I've always presumed that you would create different
                    ways for surface=clay, surface=asphalt with
                    appropriate time intervals. This gets potentially
                    very messy for city streets which may go
                    surface=dirt =>gravel
                    =>compacted=>cobblestone=>asphalt along
                    with changes in lighting, width, lanes etc. (Not to
                    mention names). I deliberately avoided this type of
                    issue when I looked at <a href="http://sk53-osm.blogspot.co.uk/2014/05/editing-historical-road-layouts.html" target="_blank">Derby
                      Road as an example</a>.<br>
                    <br>
                  </div>
                  These changes are far more frequent than the actual
                  geometry of the way.<br>

    given shared geometries, one could argue that we<br>
    should share nodes between the ways. i usually avoid<br>
    that in OSM but in this case it seems appropriate.<br>
    <br>
    JOSM can support selecting one of the the stacked ways,<br>
    but it's still obnoxious. still, it might do for now.<br></div></blockquote><div><br><br></div><div text="#000000" bgcolor="#FFFFFF">Apparently it is supposed to, but doesnt work for me with a 2-button mouse. <br><a href="http://wiki.openstreetmap.org/wiki/JOSM/Advanced_editing#Unglueing_and_untangling">http://wiki.openstreetmap.org/wiki/JOSM/Advanced_editing#Unglueing_and_untangling</a><br></div><div text="#000000" bgcolor="#FFFFFF">...snip<br></div><div text="#000000" bgcolor="#FFFFFF"><span class=""><font color="#888888"></font></span></div><div text="#000000" bgcolor="#FFFFFF"><span class=""><font color="#888888">
