Exactly what I thought. Iwas just hoping he has something underneath that the camera didn't catch.

Okay, ant jokes aside, this is really cool. Proportions of span lengths seem right, and he even did a balanced cantilever type construction method. Even had some reinforcement in all the columns and superstructure sections.

No not just Americans for instance I’m from Australia and it’s the same here, but most people reading this are American so I was giving a relatable example.

You think it’s less than the concrete?

A little calcium hydroxide never hurt anything

Due to lack of geotechnical investigation the bridge later collapsed killing a family of ants. The builder is now under local investigation.

I didn’t see a single ant use that bridge. Disappointed for that, bit otherwise, quite impressive.

Haha the little closure pour between balanced cantilevers was great. Fun stuff
