Huffer has the correct answer to my teaser.
I still say its impossible due to the weight of a standard gold bar for reasons I stated above.
But even if one were strong enough to do it, the force of impact of catching a gold bar would increase the weight on the bridge because you not only have the weight of the bar but the force with which it fell. If you had one bar in the air, one in hand and caught the other, the temporary force of catching the bar would be greater than the weight of two bars alone. And included on top of that is the force you need to exert when you toss the next one up. That's a lot of additional transferred weight that isn't being taken into account.
It's like crash tests for cars. They have a 1000 lb device crash into a car with the result of 5000 lbs of pressure. Or whatever the actual numbers would be. The point is force adds much to weight when applied.
