If any thing I think the tramway would have been more aesthecially pleasing than the concrete guideway ever was to tell the truth. Apart from the poles and the wire which are not that obvious these days you would really be hard pressed to see them. The tram tracks could have had grass grow between the rails and on each side like there is in Victoria Square and it would help the enviroment as well if done that way. Like this for those that have not seen it.
The concrete guideway is very visually intrusive, I rode my bike up as far as Klemzig not long ago and it's hard to argue that the track is low profile and unobtrusive. Next time I'll take pictures of any deterioration that I can see in the concrete as it would be interesting to note if they get progressively worse.
