I am not aware of any other significant highway building inside the M25
(whether inside or outside London) in the last 20 years, let alone 10.

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.
