Seen here is the end of the Ambassador Bridge that extends from Detroit, MI, USA to Windsor, Ontario, Canada over the Detroit River. This particular picture is of the ramp up to a proposed second crossing. However, the permits were not issued and the project was therefore halted and now stands with a drop off to nowhere. The lesson from this is quite straight forward: get your permits before you start the project or you may end up with a useless piece of infrastructure.
