A junction or roundabout is refused

The common reasons, and what to try.

The status bar always says why. These are the usual causes:

Message or symptom Try this
Too close to another junction or entry Leave more room between them, or move your road a little further along.
Very sharp angle Side roads join between about 24° and 156°. Add a bend before the junction.
Road too short here Split the road nearer the junction with N, or give it more length.
Roundabout entry won't fit The status bar says how many degrees it needs. Use the roundabout editor to place entries exactly.
Road pieces don't join Run Edit → Fix roads (whole map).

Note

Junctions with hand-made arm movements or markings may need a little preparation before they can gain another arm.
