Re: Don't Forget....
Indeed; it's the Royal Albert Bridge, and a very clever bit of design it is too.
Essentially, it's a suspension bridge that doesn't need anchors.
Normally, in a suspension design, you need to anchor the suspension chains/cables to some very solid ground but with the Tamar crossing this would have lead to an unfeasibly long (for the time) single span (because suspension bridges with multiple spans are a bit tricky). So instead of using outlying anchors to counter the inward pull of the suspension chains upon the towers, the towers are kept from falling inwards by the outward force of the upper bowed tubes. Neat stuff.
