This structure is the old Drip Bridge which crosses the river Forth. The old bridge is a category A listed structure which was built circa 1773. I thought it deserved a cache and Burns poem “The Brigs of Ayr” seemed apt for this.

In the poem "The Brigs of Ayr" the auld and the new bridge have a conversation. Here Burns is experimenting with heroic couplets.
In the course of the dialogue, the Auld Brig prophesies to the New, "I'll be a brig when you're a shapeless cairn" and in 1877, the New Brig collapsed, the arch at the south end having been damaged by floods.
This area of the Forth is often flooded but I believe that the cache is safe.
Taken from the poem -
Auld Brig
"Conceited gowk! puff'd up wi' windy pride!
This mony a year I've stood the flood an' tide;
And tho' wi' crazy eild I'm sair forfairn,
I'll be a brig when ye're a shapeless cairn!
As yet ye little ken about the matter,
But twa-three winters will inform ye better.
When heavy, dark, continued, a'-day rains,
A lesson sadly teaching, to your cost,
That Architecture's noble art is lost!"
The New Brig replies.
"Fine architecture, trowth, I needs must say't o't,
The Lord be thankit that we've tint the gate o't!
Gaunt, ghastly, ghaist-alluring edifices,
Hanging with threat'ning jut, like precipices;
O'er-arching, mouldy, gloom-inspiring coves,
Supporting roofs, fantastic, stony groves;
Windows and doors in nameless sculptures drest
With order, symmetry, or taste unblest;
Forms like some bedlam Statuary's dream,
The craz'd creations of misguided whim;
I leave you to decide whether this Auld Brig is more aesthetically pleasing to the eye than modern structures.
