end if

The Arcade Playground is a great place to try things out. What you're doing here is similar to the Arcade function DefaultValue, in which a field is returned, but does something else if that field is null. In this case, you'd like the road number returned in that instance. This should do it:

return DefaultValue($feature['RoadName'], $feature['RoadNumber'])
