From HS2:

Update: Weekend works at West Ruislip site entrance

What we are doing
We wrote to you July to advise you that weekend works would be taking place on the 7 and 8 August 2021. Due to issues with asphalt delivery, we will now be carrying out repair works to the existing access from the bell mouth junction off Ickenham High Road at the West Ruislip site entrance this weekend, 21 and 22 August.

If asphalt needs to be cut, this will be carried out on Friday 20 August, within normal working hours in order to minimise noise at the weekend.

Once the repairs have been undertaken, new asphalt will be laid, compacted and road markings will be reinstated.
Duration of works 21 and 22 August 2021
From 8am to 6 pm on both days

What to expect
Road planers, breakers, excavators and JCB vehicles will be used to remove the concrete and then asphalt delivery lorries and rollers to reinstate and compact the new road surface

What we will do
Sweep roads to remove any debris. Carry out noisy works outside of the weekend
