Weird World – Estonian Ice Road

This Estonian ice road runs over the Baltic Sea.

While easier to drive across in the winter than land, roads over water present a great danger to anyone using them. Speeds are typically limited to 25 km/h to prevent a truck’s weight from causing waves under the surface. These waves can damage the road, or dislodge the ice from the shoreline and create a hazard.

Another hazard on large lakes is the pressure ridge, a break in the ice created by the expansion and contraction of the surface ice due to variations in temperature.
