A40 Westway Speed Limit

T Jones made this Freedom of Information request to Transport for London

This request has been closed to new correspondence from the public body. Contact us if you think it ought be re-opened.

The request was partially successful.

Dear Transport for London,

Transport for London (TfL) dropped the limit from 50mph to 30mph on the A40 Westway in February 2011 whilst TfL made repairs to the expansion joints. In May 20011 TfL put the limit up to 40mph. At the time it was widely reported that TfL should put the speed limit back to 50mph by late summer 2011. One year on and we are still at 40mph. Please provide me details in electronic format when the speed limit will be return to 50mph on the A40 Westway and if it is not to be returned to 50mph the reports justifying the reasons why not?

Yours faithfully,

T Jones

Dear Mr Jones

 

TfL Ref: FOI-0699-1213

 

Thank you for your email received by Transport for London (TfL) on 25 July
2012 asking for information about the speed limit on the A40 Westway.

 

Your request has been considered in accordance with the requirements of
the Freedom of Information Act and TfL’s information access policy.  I can
confirm TfL does hold the information you require. You asked for:

 

Please provide me details in electronic format when the speed limit will
be return to 50mph on the A40 Westway and if it is not to be returned to
50mph the reports justifying the reasons why not?

 

As a way of background, the A40 Westway was opened in the 1970’s and the
expansion joints that allow movement within the elevated structure have
reached the end of their design life. An inspection showed that some of
the joints were deteriorating and were approaching the minimum safety
standards.

 

Whilst remedial work was being planned and progressed, the decision was
made to reduce the speed limit to 30mph in the interest of public safety.
This was increased to 40mph after some temporary measures had been put in
place.

 

The original programme for replacement of the joints anticipated the works
to be completed before 1 July 2012 however the A40 Westway programme
suffered severe delays due to the unexpected closure of the A4 Hammersmith
Flyover for 6 months.

 

There are 5 joints in the main elevated section of the A40 Westway which
will need to be replaced over the next few years, the 2 joints (which
extend over all 6 lanes and hard shoulder) at Wood Lane and St Marks Road
were considered those in most urgent need of replacement.

 

The works to replace the joints at Wood Lane and St Marks Road is
programmed to be complete by the end of 2012. The works carried out so far
have replaced approximately 25% of the joints at these 2 locations.

 

The speed limit will be reviewed once the inspection reports for the
remaining 7 joints (3 in the main carriageway and 4 on the slip roads)
have been received and reviewed by TfL Structural Engineers. We anticipate
a decision regarding when to reintroduce the 50mph speed limit will be
made in approximately 6 months time after review of these reports has
taken place. Safety of the travelling public will be the paramount
consideration.

 

If this is not the information you are looking for, or if you are unable
to access it for some reason, please do not hesitate to contact me.

 

Please see the attached information sheet for details of your right to
appeal as well as information on copyright and what to do if you would
like to re-use any of the information we have disclosed.

 

Yours sincerely
