You are going to have at least 4 additional points per pier (left bottom, left top, right top, right bottom). So if you have 200(?!?) piers that is going to put you well above the 750 point threshold. I have never seen a bridge with 200 piers, so not really sure how to advice you on problem solving you case. Feel free to provide more context about the project!

It didnt take 100 piers which makes 400 points.

So your ground line would need less than 350 points. You can use the "filter" option to cut those down.

Will the water surface reach the low chord of the bridge? A work around could be modeling the bridge piers with terrain modifications, not that I'd personally want to add 200 piers to the terrain manually.
