The bridge would very slowly collapse under the total weight. The truck must stay still although. Birds at least weigh at least a couple of ounces for the smallest type of bird. Although it will take some time. The bridge would not be able to hold the stress of the total weight.
no well it is any kind of bridge But since you gave up ill tell everyone da awnser The truck went half a mile right..... So... The TRUCK doesnt wiegh as much so the bird wouldnt really do anything.
