Guess where I am?

I have been doing some work for the Marine and Coastguard Agency and have been sent to a few different places to work recently. However I also now look at things with blip eyes so before would have paid not heed to this.
The underside of the Forth Road Bridge - nice eh? I hear its nearly the same age as Coronation Street - I know of a blipper that meets that criteria - an extinct auld bird ..... but we love her - even down to her last feather...
