Why destroy Laketown's bridge?

[Sauron the White]

Do you know how strong Smaug is?

Wiseguy answer #1- if you have stats as to his ablities to lift weights please provide them.
Wiseguy answer #2 - no and neither do you, its all speculation and conjecture

Actual answer to your question: You seem to accept the premise that Smaug needs to land in Laketown at all. Again, there is no evidence that Smaug intended to land in Laketown or needed to land in Laketown. Tearning down a bridge to thwart a flying creature who is attacking you in the air is nonsensical no matter how many people want to talk about land invasions.

And yet again I refer you and others to the actual drawing that JRRT made of Laketown where it clearly shows wide dockside areas that are much wider than the bridge. If Smaug had intended to land in the town, he clearly had ample space to do so. The fact is this: he did not chose to do so.

He had eye-caps like snakes. If Melkor designed a killing machine based on a reptile, wouldn't he have given it the best weapons protection reptiles had to offer? In fact, wouldn't he have give it the best weapons and protection any animal has to offer (And beyond)?

You give this information as if it were holy writ that has been approved by decades of scientific investigation. Melkor himself spent long years trying to breed dragons and failed continually to get the ones that he wanted to get. They were imperfect. How do you know that Smaug was such a perfect fighting machine with the protections you ascribe to him? Again, its all speculation and conjecture. You do not KNOW what his eyes were any more than I do. I am speculating that he had his eyes open to see what was going on. Those eyes are targets for someone on the ground close to them.

They could get rid of that bridge immediately. (examples here, here, here, here and here
Or they could end it with a drawbridge, like here and here

Thank you for those pictures. Sadly, none of them are the bridge that Tolkien himself drew and is pictured in this thread. The bridge Tolkien drew is different and more substantial with thick pillars supporting it along its span. It is not a drawbridge, or a suspension bridge and there is no mention of it being rigged for easy destruction. Just the opposite. Tolkine's own illustration - which conveniently some here want to dismiss because it supports my argument - shows a substantial structure built on many thick pillars. There is nothing to quickly "cut".
