Thornhill Road, Islington N.1 is a rather pleasant even village like part of north London. The local council is known to be keen on traffic calming measures and they plant bollards, bumps, humps, lumps quicker than most councils within the capital.
Thornhill Road is very narrow and heavy vehicles are discouraged from travelling on roads other than the main ones. The island here is a good example of a rather ugly/odd width restriction in the centre of the road.
At either end of the island we see the standard keep left traffic bollard in the middle we see two of the "bell" type bollards however either side we have these rather odd looking narrow slightly curved almost bottle like bollards that can be found to the left of the traffic bollard. This particular type of bollard can be found else where in London.
When all these bollards are placed on the traffic island/width restriction I must say doesn't it look rather ugly.
