Now I've got confused again about which bits are one way... I think I misunderstood your answer when I asked about this a few pages back, maybe because I used the wrong street names (and got left and right wrong!)
The bit I'm not clear about is Manor Mount, between the two entrances to Pearcefield Ave. I had always assumed it was one way, and really there's no good reason to go along Manor Mount from the Davids Rd end rather than going round Pearcefield but there are no signs on that small stretch.
Also, when you are coming out of Pearcefield, the sign at the junction warns you that you are coming on to a 2-way street (google street view link: https://www.google.co.uk/maps/@51.441239...312!8i6656 )

BUT... the arrows on google maps suggest it is one way.

So, if you were parked outside the church, can you legally do a u-turn to go up the hill??
