If you expand the horizon to 20 years, then that brings into scope the
Limehouse Link (and obviously a whole bunch of local roads in
Docklands - but let's not get in a wrangle about how "significant"
they are).

Also my 1988 map doesn't have the A12 extension through Leyton down to
Stratford, but I forget exactly when that opened.

On the other side of London they widened the A40, including the
stretch past Hillingdon, in the early 90's (the slightly relocated
station opened in 1992).

And I expect some of the widening of the North Circular was still
taking place in that timeframe too.

If you allow 20 years theres the series of underpasses along the A40
which abolished (amongst others) the notorious Hanger Lane Gyratory
system. This went on at more or less the same time as the widening. I
think that's less than 20 years ago.

The A40 underpass at Hanger Lane has been in place since the late 1960s.
