Thank you for your request received by Transport for London (TfL) on 5 February 2021 asking for information about works and incidents on the A2 carriageway.

Your request has been considered in accordance with the requirements of the Freedom of Information Act (FOIA) and our Information Access Policy. I can confirm we do hold some of the information you requested. You asked:

The case is in regard to the A2 motorway (London Bound) and in particular the stretch of motorway between the Black Prince and the Danson interchange London bound. We seek information for the following.

Any reports or evidence of:

That stretch of road becoming waterlogged, information in relation to works on that stretch of road, including what was spent on road works and for what reason;

Any record of how many incidents on that stretch of road were reported or known about for the year 2019 and also 2020. (stats 19?)

Whether there has ever been any record of problems with drainage of rain water on that road in 2019 or 2020.

Whether there has been any record kept or detail confirming that there is a plan to address such an issue;

Any knowledge or suggestions from members of the public that that stretch of road has been known to cause aquaplaning.

Please find attached the defect report for this section of the A2 East Rochester way. This shows all defects logged with our highways contractor that make reference to drainage, gully or flooding. The report also shows defects logged in the PEM (public enquiry manager) and these are reports that have come from a variety of sources including customer enquiries and the local borough.

We are aware that there is a drainage issue at this location. Currently we carry out an enhanced cleaning regime to clear out the gullies and drains. Further investigations as to a resolution to the issue are taking place.

Also attached is a report that shows enquiries raised by members of the public with regard to flooding, blocked drains or standing water on the A2 East Rochester Way between 9 Dec 2019 to 31 December 2020.

For the A2 between Danson and Black Prince Interchanges there have been fifteen personal injury collisions recorded; two serious and thirteen slights from January 2019 to August 2020 which is the latest processed information we have. These collisions resulted in twenty-two people being injured – see attached.

Please note that this is for both directions, not just London bound. All 2020 records are currently provisional and subject to change.

If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation.

Please see the attached information sheet for details of your right to appeal.

Yours sincerely,

Melissa Nichols
