I regularly make a journey via the A40, and coming off of the White
City flyover there was always a queue of traffic, sometimes backing up
onto the flyover itself, to lights roughly he

.. Then several weeks ago the lights were out of action with cones
blocking off the other roads at the junction. These have since gone
and the lights are back in action. Pleasingly, the huge queues which
usually developed seem to have gone. Have these lights been rephased?
Or is this just some strange coincidence? Makes my journey far more
pleasent and speedy, though I doubt the rose seller is very happy!

That junction is, I think, called Scotch Corner, and is a terrible
bottleneck for Westbound traffic, partly because the Eastbound
carriageway has a longer green to allow right-turning, and partly
because the carriageway reduces from 3 lanes to 2 shortly after.

That the traffic there has improved may possibly be due to the
re-opening of the Hammersmith Flyover, which means less traffic is
diverting onto the A40, and that it is holiday season.
