crossing.</FONT></DIV>

<DIV><FONT size=2 face=Arial>Most of those ways are one way , so routing
software would not allow many turns anyway. The only turn I could
see being currently as valid would be when going south on Lakeside Drive
and turning right onto the northbound carriageway. To stop this you need a
turn restriction relation.</FONT></DIV>

crossing roads</DIV>
<DIV><BR></DIV>Hi all,<BR> Is it ever correct for two roads to cross
physically, at the same level, but not create a junction between
them?<BR><BR>The situation I have looks
like:<BR><BR>

|<BR> D<BR><BR></FONT>With
apologies for ASCII art. Cars go from A to B, or from C to D, but they can't
turn. It's controlled by traffic lights. So, do I create the junction
represented by the +, or just let them cross over? If I create the junction,
how do I stop routing software trying to make turns?<BR><BR>It's here if want
to see it (Nearmap imagery):<BR><A
