I'd like to make a freedom of information request of the traffic volume impact and journey time changes since the closure of Hammersmith bridge. I'd specifically like to know the change in numbers between Barnes High St, Mortlake High St and Lower Richmond Rd to Chalker's Corner. I'd also like to know the change in journey times, especially between the hours of 6am and 8pm, for west bound traffic on the roads mentioned above. Finally, I'd like to know what air monitoring you're doing since the closure in Sheen and Mortlake, especially on the specific roads mentions above.

Our Ref:         FOI-3764-1920

Thank you for your request received on 4 March 2020 asking for information about the impact of the Hammersmith Bridge closure on traffic and journey times.

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy. I can confirm we hold some information relevant to your enquiry.

Hammersmith Bridge is closed to motor traffic until major safety-critical strengthening work is completed. The bridge remains open for walking and cycling. We are working to manage, as far as is possible, the impact that the closure of Hammersmith Bridge is having on the road network. We have made changes to traffic signal timings in the area to help the flow of traffic and will continue to monitor the situation to determine whether further changes are required. We have also changed the local bus network to provide new public transport options for people affected by the closure, and has launched a local enhanced Dial-a-Ride service for those people who are unable to walk or unable to cross the bridge. The closure will last until major refurbishment works to the 132-year-old bridge are complete. We are working with the London Borough of Hammersmith and Fulham to confirm the final plan for this work as soon as possible.

Please find attached the traffic count data we hold that is relevant to the roads you have specifically asked about. Please note we do not hold information on many of the roads that are owned and maintained by the London Boroughs of Hammersmith and Fulham and Richmond and you may therefore wish to contact them directly.

Information on air quality in the area can be accessed using the following websites.

We are not actively adding any monitors of our own however our environmental specialists are reviewing the data.

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

Please note, the Government has announced a series of measures to tackle the Coronavirus. It is essential for London, and in particular for all critical workers, that we continue to provide a safe transport network that enables them to make the journeys they need to.

In current circumstances, we are not able to answer requests readily and we ask that you please do not make a request to us at present.

Answering requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. In any event, please note that our response time will be affected by the current situation.
                                    
Please see the attached information sheet for details of your right to appeal.

Yours sincerely
