I fail to see what I'm missing to get this achievement so all ideas are welcome.

Tia! Achievement: An Engineer's Dream Have a Canal, Dam, Aqueduct, Railroad, Golden Gate Bridge, and Mountain Tunnel in a city I've numbered them accordingly. In the right lower corner the confirmation I've build railroad tracks from the timeline.
