"All knowledge is subjective" is a truism, thus moot and a non-starter.
What is critical in your example is objective truth.
There is no reliability whether it is your subjective assessment or the locals' assessment [subjective] is true or not? Since there is no reliability in this case, one will take the no-risk position, i.e. don't drive across the bridge.
What is most reliable is the objective truth regarding the strength of the bridge.
In this case, the objective truth is to get an independent civil engineer to assess the maximum load of that particular bridge.
The engineer independent assessment will depend on his professional expertise in using various objective scientific knowledge.
Your objective truth is a subjective evaluation faulty or not, to the individual experience is truth to the group it is agreement. The state of the bridge will always be a subjective evaluation. Granted the physicality of the bridge is what it is, but even this can only be a subjective estimation accurate or not. This is why I say that biology is the measure and meaning of all things, our subjective intelligence is our survival mode we trust it beyond authority.
Therefore, independent objective knowledge trumps subjective knowledge anytime. [/quote]
There is no independent objective knowledge, all knowledge all meanings can only belong to a conscious subject, the physical world is not conscious, objects are not conscious. All knowledge all meaning is relative only to a conscious subject, subjective in this case is evaluation of the relation between the strength of the bridge and the truck that is to cross it; with its subjective content. There is nothing in the world that has knowledge in and of itself but only in relation to a conscious subject.
As is quite well known, the above claims 150, 500, 1000 million miles are identified as
subjective claims by different subjects based on their person judgments or from unreliable sources. The scientific know,ledge is the Sun is Appx 93 million miles from Earth.
Surely you would NOT classify this scientific claim as a subjective claim like the above.
As such to differentiate the reliability and credibility of the scientific knowledge, it is generally identified as 'OBJECTIVE' knowledge as

This is a common practice, why do you want to resist it without any sound basis at all? [/quote]
Well collective subjective knowledge does tend to be more reliable than individual subject knowledge what you are talking about is collective knowledge that has been instituted for the convenience of a conscious subject to reference said collective knowledge but it is still subjective knowledge. Again, objects do have knowledge, the physical world is meaningless in the absence of a conscious subject.
In the case above there is no subjective experience to come into play, there is just trust in authority, in hearsay. Here you are assuming others know better than you. It is very thin ice from a subjective perspective and depends upon the level of trust in the experiences of the past with this particular authority.

Hearsay??
Reliance and trust of objective scientific knowledge is hearsay?
It is not merely an assumption but based on past experiences within human history and personally that objective scientific knowledge trumps personal subjective knowledge. Objective knowledge is not a 100% certainty, but its reliability is based on past proven experiences thus in general it is more trustworthy.
In general [there are exceptions], one of the features of Objectivity is testability, repeatability, if you don't trust it, you can repeat the experiments and you will get the same results.
This scientific objectivity is ultimately reinforced by intersubjective agreement [intersubjectivity] within the relevant peers.
Scientific knowledge is still subjective knowledge, it is collective subjective knowledge of humanity; you keep confusing that matter by inferring there can be knowledge independent of a conscious subject which is absurd.
j Without this condition of intersubjectivity, no thesis will be recognized as an objective scientific theory, truth or knowledge.
Because it is accepted by peers, it is independent of the individual scientist judgment or belief, thus objective via intersubjectivity.
E.g. the theory of relativity is objective, not because Einstein said so, but because Science [Physics FSK] said so.
This is still trust in authority well founded as it may be. It is the collective subjective of like biologizes concerning an experience the subject has not had in order to have subjective knowledge of the case of point. TRUST! [/quote]
Either way it is you trust your own subjective knowledge or you trust the objective knowledge via intersubjectivity.
The difference is;
1. Subjective knowledge = tainted with personal bias and beliefs
2. Objective knowledge = independent of personal bias and beliefs.
Because the subject alone is very fallible, objective knowledge within a credible FSK eliminates as much personal biases and beliefs as possible.
Harping on the term subjective and subjectivity will not generate confidence levels for others to rely upon it to generate utilities.
This is why the term 'objectivity' [via intersubjectivity] is critical to identify the knowledge is reliable as derived from a credible Framework and System of Knowledge [FSK].
As I had stated, whatever is an objective fact must be conditioned upon a credible FSK, e.g. the scientific FSK being the most credible at present.
Then we have a credible moral FSK which rely on its input from the scientific FSK, objective moral fact are derived from the moral FSK with reasonable degree of objectivity.
It is trust in the collective subject evaluation as it is instituted. I don't think we really disagree here, but personal subjectivity will always trump the collective if there is a great deal at stake for the individual. Trust will only carry one so far, our personal subjectivity is the individual's survival mode and the measure and meaning of all things. The topic above though is misleading, for the question asks HOW morality becomes objectified and the only possible answer is morality in whatever structure or forms it might take is biological extension, an expression of humanities subjective nature, the subject manifests his sentiments in outward creations.

If a person is sick and facing the treat of mortality, surely the objective knowledge from the medical community in general would trump the personal subjective opinions of the individual? Don't you think so?
It is the same with every field of objective knowledge which will always trump personal subjective opinions and beliefs.
One good example is the subjective personal belief in the existence of a God, where it is claimed creationism trumps objective [intersubjectivity] Physics.
You're a theist? insisting on the subjective belief that God created the world in 7 days?
Re morality, Hume argued that morality is extended from sentiments.
But what are sentiments grounded or emerged from in humans.
Point is whatever the moral sentiments they must emerged from the physical biological brain [there is no other place].
It is only objective knowledge [intersubjectivity] from the various sciences that can verify and justify the existence of the physical neurons, algorithm, processes, DNA, atoms, and quarks in the brain that support and generate those sentiments that lead to the issues of morality.
These PHYSICAL elements are the objective moral facts grounded on INTERSUBJECTIVITY, not on subjective personal beliefs and judgments.
My point;
Whatever is objective [thus reliable] facts is grounded on intersubjectivity within a framework and system of knowledge [FSK].
Objective moral facts emerged from the moral FSK.

What you've been talking about is the collective subjective knowledge of humanity, so that the individual does not have to invent the wheel again and again. You need to register that all knowledge, all meaning is relative to biology relative to a conscious subject; the physical world is meaningless in the absence of a conscious subject. You have made this much more difficult than it need be. Objects are biological reactions; they are how the energy of the physical world alters our constitution, our bodies. Even if you take for granted that objects are independent of biology, we still come to know them by the alterations they make to our body and this provides us with what is termed apparent reality, apparent because it's totally relative to our biology.
