The junctions weren't always grade-separated, and now that they are,
that part of the A40 usually flows smoothly. There doesn't seem to be
any point spending many millions to increase capacity round Uxbridge and
Ruislip when the choke points and flat junctions on the A40 are further
into town -- there's a long tailback every morning, which wouldn't be
helped in the slightest by extending the M40 to the Target roundabout.
There had been plans to widen the A40 near Wormwood Scrubs in the 1990s,
but they were dropped about a decade ago.

Houses alongside that section of the A40 were compulsorily purchased to
permit that widening. Anybody know if they were sold back or sold to
other people or are they just left empty ?
