I’m looking for the Mitchell and Webb sketch this thread is a parody of but I can’t find it

It didnt 'collapse'. It suffered from a known engineering principle known as resonant frequency. People walking at the same speed tend to get in line and all those feet hitting the deck at the same time caused the bridge to vibrate.
They fixed it with some strategically placed reinforcments as far as I know.
Similar things have brought down suspension bridges in the past and the variable height of the 'screening' on the sides of the new bridge are probably a way of mitigating that.

I received some info yesterday. Bridge to open 10am on 22nd. Sadly use prior to that date.

Dont need a second bridge thread as this is fairly active

The linked one is bonkers and an amusing parody.

So the OP isn't a dangerously overweight crackpot and has valid concerns ?
Agree - figured that other thread might be worth sharing in here to see what was said.

Deffo a crackpot marra.
That is actually what us civils contractors think of designersI am pretty sure they know what they are doing mate.
The machinery they have been using to load the bridge up probably puts more of a point load on the structure than a few thousand people spread along the length will on a match day.
But just to be on the safe side, you and your mate should probably avoid it and go the long way round for every match for at least the first ten years just in case. Tell everyone you know the same please. Its just not worth the risk.
PS - My profession is as a design engineer working in the construction industry. Its true what people say down the pub, none of us have any training or a clue what we are doing and most of it is just guess work. We just 'sit at desks all day'.

Its a common thing this mate. If people don't personally understand or relate to a job, especially an office based one, they assume the people in the office know nowt and are basically just 'sitting at a desk'. Its just easier for most people to do this rather try and learn whats actually being done.
The reality is, the design of this bridge will have been done by people with massive experience in similar and much larger projects. All of these people will have been educated to a very high level and the calculations they have done will have been checked multiple times at multiple stages by multiples of people and all that before the contractors even arrived on site a few years back.
I know, which is why I posted it.That is actually what us civils contractors think of designers
Just remember, without that design you don't have anything to construct and are out of a job

Pardon my ignorance, but dont they load test bridges?

I'll accept that this is football forum and I strayed from the OP's matchday structural concerns. I'm just expressing my own concerns about the functional dangers of the mixed use bridge design. It is a relative speed issue and a waving one's i-Phone whilst walking back half-pissed from a Sheepfold restaurant issue. I hope I am wrong on this.

I’m sure if we all jump up and down as excitingly as possible, it will collapse into the river.
That was because some moron thought they would try a “horizontal suspension” bridge, a classic example of why engineers should design bridges and not architects.
Fortunately, computers do it all now so it should be ok!
There’s some countries I can think of where the Civil Engineers actively discourage load testing. They only get paid if the bridge is commissioned so testing it just for it to fall down isn’t the best business practice.
