The St Thomas' solution to the Thames Path

How about using the existing Toucan from Belvedere Road over Westminster Bridge Road to lead to a new ramp running from the top of the stairs (shown below) where I took this picture to the elevated road (above) that runs along the wall beside the existing Thames Path.

And the beauty of it is that the road belongs to St Thomas' Hospital who are particularly concerned about the safety of Thames Path users and a member of the NHS which is desperate to have people adopt a healthier, more active lifestyle to cut down on their costs.

I can't imagine why they haven't done it before.
