<p>In <a href="https://github.com/openstreetmap/openstreetmap-website/pull/1693#discussion_r154533979">app/assets/javascripts/index/directions.js</a>:</p>
<pre style='color:#555'>> @@ -111,6 +113,20 @@ OSM.Directions = function (map) {
     return endpoint;
   }
 
+  $(".directions_form .reverse_directions").on("click", function() {
+    var input_from = endpoints[0].input.val();
+    var input_to = endpoints[1].input.val();
+    var latlng_from = endpoints[0].latlng;
+    var latlng_to = endpoints[1].latlng;
+
+    endpoints[0].setLatLng(latlng_to);
+    endpoints[1].setLatLng(latlng_from);
+    endpoints[0].input.val(input_to);

</pre>
<p>What about if you include a <code>route</code> parameter in the URL with the actual lat/lon values? I think in that case it will use those rather than rerunning the geocode? So something like:</p>
<pre><code>OSM.router.route("/directions?" + querystring.stringify({
  from: $("#route_to").val(),
  to: $("#route_from").val(),
  route: from_lat + "," + from_lon + ";" + to_lat + "," + to_lon
}));
</code></pre>
<p>although I haven't looked at how to get hold of the lat/lon values yet.</p>
