I cycled it southbound for the first time this morning, joining from Pilrig Street after seeing the "not in use" signs were away. It was fairly pleasant.
1) At the first bus stop bypass the three pedestrians, that were standing in the lane, moved off it as I approached. Smiles and "thank-you"s
2)At the Albert Street "give way" there were two vehicles waiting to join Leith Walk, and the second one had left the bike lane section clear. Possibly the natural gap he'd leave anyway, but I like to give the benefit of the doubt...he got a wee wave of thanks :)
3) At the second bus stop bypass at Magnet, more people were standing in the bike lane, and one in particular showed no intention of moving out of it whatsoever. I went round her on the tactiles.
I'm not sure what info is at the bus stop, but perhaps clearer instruction to waiting bus passengers would be helpful...
4) The light timings were in my favour when I rejoined the main carriageway after crossing Brunswick street, so there were no cars to consider....
I did note that on the way down (Northwards)in the evening yesterday (after seeing twitter chat that it was open) that the "not in use" sign about 3/4 of the way down, high on the lamppost was still there - that combined with the narrow pavement thanks to the Shrubhill works boarding, might have explained the grumpiness of a couple of peds at that point....
On the whole though, I liked it. I can see it's value more when Leith Walk is really busy, with multiple buses and tail-backs / double parkers. Provided it's kept clear...
