However even if you want to use the upstream bridge (which wouldn't

to come down to ground level, walk towards the river and then
(presumably!) climb up again to the level of the bridge? Is there an
obstruction (eg a building) that prevents the high-level walkway from
continuing between Belvedere Road and the upstream bridge. Multimap

shows a path, but I presume it's a ground level.

That is correct. For a while Jubilee Gardens (the former site of) and part
of the car park have been either covered in temporary buildings or
out-of-use. Jubilee Gardens was the site of many of the EJL (formerly JLE)
office and changing room Portakabins. The high level walkway is a bit of an
oddity now in that it just seems to come to an abrupt and pointless end at
Belvedere Road. Like you, I find it surprising that it wasn't continued on
to the South Bank and either linked to the upstream Hungerford Bridge (I
refuse to refer to them as the Millenium Bridges!) or taken down to ground
level at that point. For a while it was possible to walk across the car park
to the upstream bridge over the river but that too has been closed recently,
requiring a detour via the Festival Hall approach and the downstream
Hungerford Bridge or a circuitous route towards County Hall and across the
grass to get to the upstream bridge.
