CREWS worked through Monday night to reopen the A40 between Hillingdon Circus and the Swakeleys Roundabout - and traffic was using the stretch by the early hours of today.
Meanwhile, the big clear-up continued in flood-hit homes and businesses after the freak storm, which dropped two months' rain on the area in just an hour.
These pictures from reader Michael Peters, of Ruislip, show the scenes on West End Road, Ruislip Gardens, and the bridge under Ruislip Gardens station I n South Ruislip as drivers struggled to get to work.
Our thanks to him for the images, and if you have any others let us have them at firstname.lastname@example.org. We will give you a credit.
