FOI request detail

Roadworks along Gunnersbury Avenue (A406)

Request ID: FOI-0086-1718
Date published: 08 May 2017

You asked
We act for two clients who recently received notices of intended prosecution for alleged speeding along Gunnersbury Avenue. We understand the speed limit at the time had been reduced from the usual 40 mph to 30 mph because of roadworks. We would like to know, please, what signage was placed advising motorists of the reduced speed limit, where these were placed and the date on which they were put up. If additional signs were, as we believe, installed in July 2016, we would like to know why this was, please, also their position and the date they were erected .

Our ref: FOI-0086-1718

 

Thank you for your request received by Transport for London (TfL) on 27 March 2017 asking for information about roadworks on Gunnersbury Avenue.

 

Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. I can confirm that we do hold the information you require.

 

A temporary 30mph speed restriction is in place on the A406, north of the Chiswick roundabout. The limit on the A406 Gunnersbury Avenue has been reduced to 30mph from 40mph, to ensure the safety of all road users and contractors working onsite to replace the Power Road Bridge. The Temporary Traffic Order allowing for the speed limit reduction came into force on 2 June 2014. Signage for the temporary 30mph speed limit was installed in May 2015 to coincide with the start of bridge works. Signage for the 30mph speed limit was installed at the termination points of the limit, as described in Temporary Traffic Order GLA 2014 No 0269.

 

The 30mph limit described above was extended in the northbound direction for around 150 metres to a point adjacent to Gunnersbury Park under Temporary Traffic Order GLA/2016/0237 around 10 July 2016. Local stakeholders had requested this extension, to ensure that the full extent of a pedestrian diversion route (which was in place as a result of the bridge replacement works) was contained within the extent of the 30mph limit.

 

The Metropolitan Police checked all the on-site signage and they confirmed that it was in accordance with the Traffic Signs Regulations.

 

Additional carriageway markings were installed overnight on 13/14 July 2016. Three pairs of large “30” signs (TSRGD number 1065) were installed on the carriageway of the A406 Gunnersbury Avenue. This included one pair at the terminal signs just to the south of Larch Drive, one pair by the safety camera pole near to Manor Gardens and a third pair approximately half way between those two points.

 

The additional signage and carriageway markings were provided in July 2016 in order to raise awareness of the temporary 30mph limit, and are over and above the legal requirements.

 

If this is not the information you are looking for please do not hesitate to contact me.

Yours sincerely
