Engineering Question : Does the bridge need a weight limit for boats ?

to answer your question ships barges are limited to 1350 metric tons of cargo so yes their is a weight limit

Not really a new twist.

However
It only needs to be designed to withstand the weight of the water!
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded.

correct I believe the limit is placed to keep the barges which I think i read were standardized from scraping bottom

Hmmm...I know and have no arguments with that statement, but in this specific situation, there's more to it. 'Displaces' is not a right term here, as I am sure the water in that canal stays there, despite addition of new vessels (ie, it does not overflow out of it).

Lessay the water in that acqueduct weighs 50,000 metric tons. Now if a barge weighing 1,000 metric tons is added to it, the total weight now carried by the acqueduct is 51,000 metric tons. So the canal better be designed to carry the added weight of all the vessels in it's water.

Or somebody tell me if it's way past my bedtime and i shd head to bed .

Yes, wonder how that works - the link did not give details.

As it was stated; "not really a new twist", there is a place in eastern England (can't remember the place, somewhere in East Anglia, no pic's) that has a road going under a railway bridge which has a barge canal going over the top of all of them. I remember driving under it on the way to Lakenheath when I was stationed in the UK many years ago.
