Reverse: Deep Beneath The Detroit River

On this day in 1930, the Detroit-Windsor Tunnel was dedicated. And 82 years later, it remains the fastest way to get between the American and Canadian Motor Cities. The tunnel was dreamed up in 1919 by officials from both countries who thought it could be a fitting memorial to troops who died in World War I. There was a bit of a scare campaign against the tunnel by proponents of the Ambassador Bridge, who warned of the dangers of subterranean carbon monoxide gas. No worries: in the first nine weeks it was open, 200,000 cars traveled through, some bound for the Windsor Ballet. [History]
