You can take a look with Bing Streetside. It's literally a smaller-than-the-carriageway strip with marginally distinguishable markings.
You just drive onto it.
The wiki said, that lane was (paraphrased) for parking on a lane (reducing the available lane width) where street side isn't part of the lane.
Interested to hear your thoughts from Bing Streetside :)
