Road Collapsing

Reported via iOS in the Roads and Carriageways category anonymously at 18:39, Saturday 7 February 2026

Sent to Oxfordshire County Council less than a minute later. FixMyStreet ref: 8862358.

So you’re aware, the road outside 30 Wellington Street in Thame looks to be collapsing along the line of the sewer. A trench has formed that causes a bump when cars travel over it. It’s about 40-50cm wide and about 2m long. It begins at the site of the sinkhole that you filled in. It looks to be a Thames Water issue continuing the issues at the location. Thames Water have been phoned and will attend.

Council ref: ENQ261081774

  • Continuing to sink. Picture taken today. You can see the nearby tarmac patch in the 2nd image where Thames Water were working relative to the sinkhole that looks to be developing again.

  • Having driven over this tonight, it appears that this has sunk further from the picture above. I would suggest this need looking at fairly urgently incase there is little below it.

  • This is getting worse and could cause a serious accident if it fails when somebody is driving over it.

    Can we have an update as to what is happening as this needs to be fixed soonest.

  • Ths sunken area contunues to sink further on a daily basis. There is now a big 'thump' of the suspension and a roller-coaster ride every time you cross the thing.

    Is anyone going to do something before a cyclist at least gets severely injured?

  • The road is now being to sink at the centre line of the road, where the zig zags are for the zebra crossing, on the same side of the zebra crossing as this depression. It looks like it’s not just this area. McAllister were UV-lining the sewer here 6-7th Feb, the day before this all started sinking.

  • These puddles along the centre line show the possible other deformations in the road. Thames Water noted these. The large deformation is not holding any water in the rain, meaning that it is draining somewhere.

  • The patch is now sinking and the centre line of the road has formed a shallow trench. There also looks to be a new void developing on the other side of the zebra crossing. This started developing immediately after Thames Water line the pipe. Could they have messed it up and water be travelling externally to the pipe?

  • The section of road where the patch is now worse then previously shown with one of thenside sinking considerably more than the other with a loud bang if you drive over the sunk section.

    This needs investigating ASAP as clearly the sub surface is not sound.

  • There are now cracks in the tarmac showing the surface is breaking down either side of the sinking developing in the centre line. The circled sinkhole at the end of Swan Walk is deep enough that I tripped over it last week. Bring Thames Water back in.

  • The tarmac patch for the original sinkhole that opened and OCC applied, looks to have given way. The newer tarmac patch applied after the Thames Water work is now stretching into the hole. It will likely open up when a car travels over it in the next week. It has gone extremely worse this week.

  • The centre of the tarmac patch is now heavily dimpled and is elastically stretching below the surrounding road surface into what can only be a void (after all - the elastic deformation has to be going somewhere!). It has also risen up at the edges where it used to butt against the surrounding road surface.

    This looks hazardous and set to fail with maybe a heavy vehicle or enough vehicle crossings to deform the surface beyond its elastic limits.

  • Taken Friday night, you can see the tarmac visibly sagging as it stretches through the hole beneath.

  • The sinkage is very significant now - in excess of 150mm down with a secondary area forming just beyond.

  • This is becoming a very serious problem, I drove over the sunken part of the road and there was an enormous bang. I don’t think my car (mini) was badly damaged, but I haven’t fully investigated yet. It’s getting really bad and needs fixing asap.

  • This needs sorting ASAP!

  • There are now cracks developing in and around the deforming road surface.

  • Given the issues in Wellington Street last year that led to many weeks of multipole closures and repairs by Thames Water - and also that is immediately adjacent and in line with the prior waste water failures - has anyone in the Council reported this to Thames Water before someone and their bike or car either is forced to swerves into a crash or falls into the developing hole?

  • The puddles this evening show that the depressions in the centre line of the road are worse, holding more water than similar photos taken previously. The sinkhole has a massive crack in the side of the tarmac covering it.

  • It looks like a member of the public has found a traffic cone and tried to make it safe. It’s big enough now for a tyre to go through it and the body of a car to touch the ground.

  • Thank you for bringing this issue to our attention. While Oxfordshire County Council is not responsible for this problem, it is an ongoing issue for Thames Water to recify who have also barriered off the section]. The report will now be closed on Fix My Street.
