"The Rotunda building was initially built in the 1990s when the station
was constructed, but is currently used only by Crossrail construction
workers."

What are Crossrail workers doing so far north of the line, which is in
the vicinity of the Lower Lea Crossing?

Also, I notice that a couple of loops west of there is a blue bridge
over the Lea with an abandoned railway bridge just south of it. It seems
surprising that a bridge that was built for trains should have become
too weak to carry pedestrians, or is that wrong thinking?
