Is it weird that I just kept staring at the picture of the bridge and trying to figure out how it stays up? You normally see the posts under the bridge, but for this one, they're out to the side. That allows more traffic underneath, but it also doesn't transfer the weight directly to the ground. There has to be tremendous pressure on the inner curve where it goes from horizontal to vertical beam.
In other news, that's cool there's a neighborhood where things are actually affordable and people are able to work collectively to turn the neighborhood around. Small, local businesses are ones that normally pour right back into the community and if there's a larger group of them, they'll just continue to help each other grow... rather than just boosting someone else's balance sheet.
