#26: Bollards That Are Retractable
Bollards are no joke. These heavy-duty, durable posts are used in cities worldwide to manage traffic, control access to certain areas, and help with crowd control. Overall, bollards are an excellent invention that helps create boundaries that keep pedestrians safe. This installation in Amsterdam takes the meaning of bollards to a whole new level.
These steel bollards are retractable. That means they can go up and down according to the situation, which is totally awesome. There’s no better way to block motorists from entering a pedestrian-only road than with these nifty posts. These retractable bollards are occasionally used on roads that only allow buses and pedestrians. That means any car that tries to tail it in behind a bus is in for an awful surprise.
