L4+ Newcastle Upon Tyne - junction box issue

Would a L4+ please take a look at adding a junction box here please? I had added one a month or two back, but seemed to have trouble with getting the route highlighted through the permalink to be captured as a valid entry point into the JB and I wonder whether this relates to the UR just south of the roundabout.

I’ve given the nodes a jiggle around here and tried readding the JB myself, to no avail. It gives the entry point directly from the roundabout, and for entering the roundabout from the south, but does not give me the fast slip bypassing the roundabout as an entry point.

This may well be me misunderstanding JBs! :lol:

You cannot have an entry and exit of a roundabout on the same node, you will get to take the 0th exit instructions.

Move the exit segment connection to a separate part of the roundabout, then you should be able to add a JB and disable the route.
