ZTZ-99A tank via LKJ86 Nice shots look solid. Tank does not travel by its own power to battle field they have to be transported by truck

That’s standard practice. Not a flaw the norm.
Tank tracks even with rubber pads are not very nice to roads and the tank takes a lot more wear and tear just driving around than wheeled vehicles. It’s easier to put the tank on a transport when not operating than it is to drive them around over hill and dale.
This is why wheeled APC and IFV are considered to have advantages. The Tires don’t do much more damage than most heavy farm equipment. They place less stress on the vehicles and demand less TLC.

I know that but ZTZ99A look well proportion and compact easier to negotiate small and narrow road ,overpass, bridges Judging by photos
Assuming 55 ton ZTZ99A and 20 ton truck and trailer assembly It should be within 80 ton bridge limit

Always wonder how much weight limit of bridge really matters. It's not like bridge would immediately collapse once you run a overweighted tank over it. Consider many truck driver would carry cargo that weighs sometimes double of the weight limit and those bridge seems fine. I would say the weight limit thing only restrict defender cause they need to operate their tanks on these bridge for the long term during peace time.

There is such thing as bridge limit Here is DOD bridge limit formula It depend on how many axle

What is designed weight capacity for bridges?

I'll try to put it in a nutshell. The common practice in bridge design is to assume different load scenarios - e.g. queues of long heavy vehicles such as that shown in Hendrik's post above (with no restriction on the number of traffic lanes used); or special load cases such as a truck transporting an exceptional load such as a transformer or in our case, a tank which is normally lighter than transformers, but with some restrictions on traffic. For the latter case, depending on your country you may have restrictions on the use of the adjacent lane, or assume no other traffic within a distance in front of / behind your special load, or a combination of both. These loads, along with other loads such as self weight, wind, snow, pavement surfacing, etc. are then factored up to compensate for inaccuracies in load assumptions. The material strengths of the bridge are also subject to material factors downwards to compensate for any deficiencies in workmanship. The load limit signs we see on bridges show the unfactored design loads, not the load under which it will immediately fail (what we call the ultimate limit state).

Well with how often bridges and overpasses in China collapse due to negligent companies overloading their trucks I would say that the weight limit on bridges are pretty serious.

Which comes back to the Doctrine of the Army using the tanks and condition of the bridge.
If the bridge is in good repair and rated for it a tank will easily cross. 17C6A35B-DC90-4079-84EC-CED8B7A38838.png
But it doesn’t take an Idiot or a Crazy man to know that an easy way to slow the advance is to cut the bridges.
In conflict blowing bridges is a well established method of preventing advance.
Although simple repair like laying planks will easily allow infantry to cross. Vehicles and especially heavy ones demand more solid structure.
This is why Russian tanks push to be very light weight so that the Bridge can be reenforced more quickly then that demanded by a heavier tank. This is also why many armies have scissor bridges and pontoon bridges so that they can lay a rapid bridge of their own and bypass established bridges that could have been mined or sabotaged.

Reminds me of how knights carried their equipment on a draft horse and actually fight on a destrier.
