I have always thought the exits around Waterloo are a mess. Very difficult to navigate.
I don’t know why they don’t make more of encouraging passengers from the more southerly platforms heading towards South Bank out under the clock and onto Cab Road well in advance of the Victory Steps.
The Victory Steps feel like the de facto main entrance but they are not good for the purpose, too steep for many.
I would personally reconfigure the Cab Road area where all the bike racks are, make it the de facto main exit, the main entrance for step free and then sort out properly the absolute mess of obstructions on the approach in general. There seems to be a lot of wasted potentially valuable circulation space on Cab Road in general.
As for the walkway in the sky, most of these experiments didn’t work. This one might have been better because the station is elevated, as is the Hungerford Bridge so you were linking 2 elevated things together.
