I noticed there are a number of roundabouts in the area without an
explicit oneway=yes, and a couple of slip roads and part of the New High
Street were also missing oneway=yes. This may be a contributing factor
so I fixed what I found. Don't know how long it will take OSRM to get
the updates into the routing network though.

It is a strange one and has me totally baffled, so hoping someone here
can help.
A simple U-Turn around a roundabout, adds a detour along Llangollen
Road, to then use Tower Hill to turn around and come back to the
Roundabout. Dragging the start point around the roundabout does
eventually work once you have passed the first exit.

Using the same finish point, but moving the start to the A483 exit slip
road has another strange result. There are no obvious turn restrictions,
as they are all possible, with different finish points.

I am assuming it is more than a problem with OSRM. Otherwise I guess the
only option is just to re-survey, delete and redraw the area.
Thanks Phil
