There could be drainage issues, I'm not a hygrologist, and I haven't looked at the area. That could add cost and complexity to be sure.
All I know is that a 1/4 km long bridge and causeway is very far from my preferred option, it squanders the opportunity to expand the greenspace, as well as limits the transportation connectivity options, and frankly, a 1/4 km long bridge is just not likely to be a particularly pleasant experience, summer or winter.
