Yes there should be a node at the crossing. 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.

The situation I have looks like: C | A-->-----+----->--B | v | D 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? It's here if want to see it (Nearmap imagery): http://www.openstreetmap.org/edit?lat=-37.85348&lon=144.979389&zoom=20 Queens Rd southbound branches to become Lakeside Drive, crosses Queens Rd Northbound. Sorry for the noob question, just wanted to make sure I get this right.
