These things happen all the time all over the world. Just google "US highway collapse" and see how many different incidents you get.

I don't think so. It is not an uncommon design everywhere.
Los Angeles
Cape Town. don't be fooled by the bulky column on the top. The supporting point is a much smaller joint. And the load is only supported by the narrower base.
Somewhere not in China
There is no good design if it is abused beyond its specification. Any good design will be crushed under exceeding force.
The proper question besides the construction quality are:
- Is the truck or are the trucks overloaded regardless where they were?
- Is the truck(s) overloading the bridge even if they are properly loaded?
- Is there any sign of warning of permitted load?
- Is there an off ramp for "overloaded" lorries to get off at or after the sign?
- Did the driver ignore any of these signs and ramps?
coming from Ministry of Transport spokeperson, blaming the weight-overrated heavy truck is too convenient. The collapse highway had 3 lanes and a narrow column to support the bypass, This looks like a accident waiting to happen. It may be acceptable if the highway was restricted to 2 lanes only. The torsional force from unbalanced heavy load on the outer lanes will cause the bypass to tilt and collapse.
I don't follow every incident, so don't count me for the answer. This is the 2nd incident that I am aware of. The last one happened in Jiansu. It was the fault of the driver who overloaded his lorry by many tonnes. And that many tonnes were put on the area of less than 20 square meters.
No, I don't give a dime to what the western media say. There is no way anybody can do anything if they are determined to lie. If you bother, you loose. Just take the vaccine as an example, have they stopped BS? Are they going to stop? If anyone outside of China believes them, then there is no way you can bring them back because they want to believe.
A good design will anticipate the worse case scenario or maximum possible load and will put restrictions on avoid such overloading from happening, i.e. restrict traffic to 2 lanes if the supporting structure is unable to support excessive loads.

So this is what real life Khorne-flakes looks like. The two moms were more formidable. Probably more manly as well!
So you are saying that the bridge has to support unlimited load? The two lorries weighted more than 200 metrics tonnes together. That is 4 main battle tanks. How many roads in the world allow them to travel in close formation?
Post Breaking & World News! III NO DISCUSSION!! demonstrated three or more lanes standing on a single supporting column. That is just a random search in 5 minutes.

Then there is no good design in the world, because the maximum is infinite. In the Wuxi incident that you quoted, more than 200 metric tonnes equivalent to 4 main battle tanks in close succession. I don't think there is any highway viaduct on this planet is designed good enough for this scenario. And I am sure this scenario is not the worst nor maximum possibility, because if this incident did not happen that day, a 3rd colleague of the two will join them with another 100 metric tonnes another day until they crash another bridge.
Some of these errant Chinese truck drivers just wanna skimp and skirt by taking a shortcut and therefore going on a bridge not designed to withstand their truck load.
