Anti suicide fencing was installed on bridges crossing the Cape Cod Canal in the early 80's. These are closely spaced rails without any chain link. I suppose you can still drop a small object into the canal below but the smooth rails without chain link make it very difficult to climb over. The state police barracks are at the foot of the Bourne Bridge so I guess that a jumper would be slowed down in a jump attempt long enough for the police to respond.
Smaller roadway bridges have similar fencing and chain link as well. I suppose that the main function in this case is to prevent objects from being dropped on to cars. Anti suicide would be a secondary benefit in this application. Hence the "tumble home" or inward curvature and height being added to make it difficult to scale over.
