have not opened a physics book in 10 years but that is my guess...

But, it would be a good chunk of weight that is there to begin with.

if an object sinks it'* mass > mass of water displacement.

Barge captains will now be able to ship loads of up to 1,350 metric tons – the equivalent of 50 truckloads – over the 34-meter wide and 4.25-meter deep water bridge.

Gumball, how sure are you of that answer? It doesn't seem logical in a closed system; the displaced water has no place to go so the level raises.
Maybe only one lock is closed at a time? (ie - open system)

if the ship is 120 meters long by 12 meters wide with it'* hull going 4 meters deep it would only displace 5760 cubic meters of water.
i don't even know the vessels are that big. but in any event the weight of the ship is dispersed through the whole bridge through the water. per square meter on the bridge floor force per ship sized above would only increase ~ 4%
so that stated open loop vs closed loop is negligable.

Now put 10 of those ships on the bridge.
I'm really curious of the physics behind the answer and I'm no mechanical engineer but I'b be willing to bet that only one lock is closed at a time to minimize the load on the bridge. I haven't found anything relevant on google yet either.
