[Routing] Missing a turn?

[Philip Barnes]

I have been trying to fix this routing problem reported on mapdust,
http://www.mapdust.com/detail/3004250.

On OSM, it can be seen here http://osm.org/go/eu5TeWZR.


Despite its minimal description, I can see exactly what the problem is.
Thornton Lane, from the south continues into Main Street. Thornton Lane
from the north gives way at the junction. The problem is that routers
ignore this turn, I know it is virtually straight, but it is a turn. 

Travelling north, http://osrm.at/1MH, in the absence of a turn
instruction drivers are likely to continue onto Main Street. 

Is there a way to tag this?

Thanks Phil
