Even when they’re built from concrete and steel using proven engineering principles, I still get anxious when crossing certain bridges. So there’s less than a zero percent chance that I’ll ever try crossing this 1,640-foot test of bravery in Siberia. It looks like it could instantly collapse under the weight of just a single snowflake.

The bridge, which spans the Vitim River in Siberia, Russia, was built for use by trains, which explains the lack of any safety barriers. The bridge has long since been replaced by a much safer structure, but after the rails were removed it was never torn down, and it eventually became part of the Baikal–Amur Mainline (BAM) road in Siberia, which attracts adventure seekers and common-sense-lackers like Martin Remiš, who successfully traversed the wooden peril in his Ford Bronco.
