Here's some other examples just down the road from your example. This example is of how the SPUI is typically mapped but seems lacking <a href="http://www.openstreetmap.org/#map=19/33.65519/-112.00010" target="_blank">http://www.openstreetmap.org/#map=19/33.65519/-112.00010</a>.

The lights hang off the freeway bridge put I placed them at the stop lines on the pavement. The additional junction and routing relations are a nice plus in your example.<br>
<br></div>Note that we have had one mapper in the area that removed highway crossings because he thought that they were excessive. I wonder what he will do with turn restrictions? I don't know if his feelings are based on the way iD or Potlach displays these types of features.<br>

<br>
Here in Utah, we have a DOT that is really into SPUIs (Single Point<br>
Urban Interchanges). They are supposed to increase traffic flow in<br>
high volume freeway to surface interchanges.<br>
<br>
Here's an example:<br>
<a href="http://www.openstreetmap.org/?#map=19/33.62963/-111.89021" target="_blank">http://www.openstreetmap.org/?#map=19/33.62963/-111.89021</a> (not in<br>
Utah)<br>
<br>
This is one I (re)mapped yesterday. I try to stay close to the<br>
situation on the ground, the result being a lot of turn restrictions.<br>
I have also seen situations where all the ramps and connectors come<br>
together at the center, easier to map I guess.<br>
<br>
I am looking for opinions on how to map these complex interchanges.<br>
Could a few of you have a look at what I did and comment? Thanks.<br>
