Well... would you mind listing your academic achievements and degrees if you are so are inclined to bash peoples' intelligence, so that you can show people what you're up against??  And this engineer, was it a civil engineer? A structural engineer? A combat engineer? ... Also, as previously stated the bridge is built stanchion by stanchion and so the stanchions are made at different heights to keep the bridge level above the water... your whole premise of flat earth because the bridge is flat is unrealistic and plainly stupid... it's not account for the height of each support and also it doesn't account for camera angle... If you were to stand on the bridge and take a picture to see if it curves over a straight line, it might be a better representation than an overhead view that plainly cannot show how far it extends flat... but make sure you cover the horizon well enough to show that in any picture with enough of the horizon showing, the corners will start to show a dip in them as the Earth is most definitely round... 🌎
