I imagine the supporting structure of the causeway is a lattice-work of iron and steel, similar to the Eiffel tower, which is also comparable in height. The Eiffel tower was built in 19th century so I guess in smaller scale, as it currently is in the novel, the causeway would be (barely) technically possible. But I agree that there is no way they can complete the network. I cincerely hope canonically that won't happen.
