It was said that enlarging the connaught tunnel for crossrail was "impossible"
but they managed it.

Only by a complete change of plan and draining the dock to
re-cut-and-cover, rather than widening from the inside.

Doesn't matter - they did it. Given how long the ELL was closed for to convert
it they had plenty of time

The critical timing was how long they could close the dock for, as it's
on the route between the river and ExCel, which has an annual boat show.
There was a documentary about the project in the Autumn, and they
finished it by the skin of their teeth.
