We are carrying out works to strengthen, stabilise and repair Bishopsford Road Bridge.
We will update this page as and when there are developments on site, to keep you updated on the progress of the works.
We started strengthening works on 23 April 2019 as part of the annual highway maintenance scheme. We planned to complete the strengthening works by 22 July. Due to the floods that occurred on 10 June, the river bed and foundations of the bridge were "scoured" (eroded) and therefore undermined. This led to the partial collapse of the northern arch on 14 June. We believe that the southern arch has been unaffected and the central arch has been affected slightly. Due to the failure of the bridge, the road will continue to be closed until the bridge has been repaired and is safe for pedestrian and vehicular traffic.
1 October 2019 update
We have completed works to stabilise the bridge and are now assessing options to repair and re-open the bridge.
Following the 10 June flood event a number of work-streams are being undertaken and we want to keep local residents and businesses updated.
During the flood, the river bed was "scoured" (eroded) up to 4m deep and undermined the foundations of the bridge. This led to the partial collapse of the northern arch on 14 June. The southern arch was unaffected and the central arch suffered minor structural damage. Due to the collapse of the bridge, the road will continue to be closed until options appraisals to repair or replace the bridge have been completed.
We are working with FM Conway and the Environment Agency and have focused our attention on stabilising the remaining structure to prevent further damage and make the bridge safe for inspections and for workers to carry out repairs.
We have completed crack-injection and underpinning works below the bridge to stabilise the central arch. The scour hole on the upstream side of the bridge has been filled with stone and gravel. The scour hole under the northern arch has been filled with marine concrete to stabilise the northern arch and create a safe platform for further works.
Now that the existing structure is stable, you may not see workers active on-site whilst we undertake assessments and complete feasibility reports to advise on repair options.
We have also installed CCTV under the bridge to monitor water flows and river levels as we approach winter.
We have commissioned independent reports to advise on next steps to re-open the bridge:
The "what happened?" report
Specialist advisers are now working on this report, which will look back at the flood event and contributing factors to the bridge's partial collapse.
The "what next?" report
We are arranging this report to look forward and provide detailed inspections, surveys, costing and design options for the repair and/or replacement of Bishopsford Bridge.
Until these studies are complete, we will not be able to advise on the timescale for the road to be reopened. We will report back when the timescale is confirmed.
CCTV / ANPR cameras
CCTV / Automatic Number Plate Recognition cameras are installed to enforce against motorised vehicles illegally driving over the footbridge. Pedestrian guard rails have also been installed as a further deterrent, along with signage for pedestrians and cyclists.
Ravensbury Park lighting
Lighting has been installed on the footpath in Ravensbury Park to enhance safety for users of the footbridge. Vegetation has also been cut-back to improve safety and litter bins are being emptied more frequently. We will also be laying a more durable surface on the path at the entrance / exit to the park and the northern side of the footbridge.
Ravensbury Park / London Road wall
The brick wall alongside London Road and the park has been raised as an issue where people, particularly children walking to school, feel unsafe. As the evenings get darker, the Council believes that reducing the height of the wall to knee-height will improve security and visibility for pedestrians and cyclists and reduce anti-social behaviour. We are looking into this and will come forward with a solution shortly.
Bus diversions are running well. However we have listened to feedback and continue to negotiate with TfL to secure additional services towards Morden Station. We will keep you updated via our website and newsletter with news of additional services.
Essential gas works
When the bridge partially collapsed, gas mains were re-routed to ensure that Ravensbury Ward maintained a gas supply. As winter approaches and the demand for gas increases, Southern Gas Networks need to undertake essential upgrades to ensure an even supply of gas. Works will commence 21 October for nine weeks on the following streets: The Drive, Arras Avenue, Victory Avenue, Leonard Avenue, Seddon Avenue and Florence Avenue.
Roads will remain open and bus routes will not be affected. We will monitor traffic flows and take any action, if needed, to minimise disruption.
14 September 2019 - drop in coffee morning
On Saturday 14 September 2019 there was a drop-in coffee morning on the Tooting and Mitcham Hub side of the bridge where council officers and local councillors were present to give residents an update on how works are progressing.
15 August 2019 update
FM Conway have undertaken crack injection and underpinning works to stabilise the central arch. The scour hole on the upstream end of the bridge has been filled with stones and gravel. FM Conway will be backfilling the scour hole under the Northern Arch from 15 August. The Environment Agency and the Council will be supervising these works.
Thames Water has isolated the water pipe along the bridge deck and installed a 2nd temporary rider to supply water to properties. UK Power Networks will isolate the High Voltage cable on 15 August at 8:00 AM and re-energise at 6:00 PM during the backfilling and dewatering activities.
Once the stabilisation works are completed, a full inspection will be undertaken followed by a detailed feasibility study and design options analysis for the permanent works. Until such time, we will not be able to advise on the likely timescale for the road to be reopened.
We have installed lighting columns in the park, along the path currently used by pedestrians for safety and security reasons. CCTV and signage has been installed to deter motorcyclists from using the pedestrian and cyclist's footbridge. The sockets to power the ANPR/CCTV cameras have been installed and the ANPR/CCTV cameras will be installed in the coming week.
Transport for London (TfL) have arranged for bus route 280 to serve Bishopsford Road, Wandle Road and Morden Road and this has been running since the morning of Saturday 20 July. TfL have also added a temporary stop on London Road at the junction of Mitcham Park.
We have displayed information boards along the diversion route to inform the public that the local businesses are open as usual and accessible for local vehicular traffic.
Improvement works have been undertaken to level the gravel footpath leading to the pedestrian/cycle footbridge to ensure safety of the path users.
Guardrails will be installed on 16 August subject to good weather conditions on either sides of the footbridge to act as a further deterrent to motorcyclists using the footbridge. This will also be enforced with the ANPR (automatic number plate recognition) cameras and fines will be issued to offending motorists.
Any vegetation encroaching into the gravel footpath has been cut back and the litter has been cleared. This will be monitored regularly
The temporary traffic lights at the junction between Morden Road and Wandle Road have now been removed as the SGN gas works are now being carried out in the footway.
We apologise for the inconvenience caused and thank you for your patience during this time.
