An open bus shelter manufactured from (mainly) iron, the one wall and two supports must be strong enough to support the large roof above, though this is helped circumvented by the main body of it being manufactured of a light cheap plastic with an iron "skeleton". It also needs to be strong enough to, for example, handle extra weight through snowfall, etc. Because of the relative large size, most of the force is exerted on the two foremost supports; this helps to spread the compressive force away from the main body.
The structure itself has foundations sunk below ground to provide added stability against strong winds. The 6 seats are affixed using 4 large wall brackets, essential to handle today's morbidly obese generation.

An interesting post. I catch the bus every day and never really thought about it too much. Extreme weather conditions could cause bending, so the supports are buried to counter this and keep them rigid. Nice one
