The Donkey Bridge
This small bridge provides pedestrian access from the western end of the town to the foreshore and the coast road. It is 3ft wide and 5ft high.
This access existed in 1880 from the Beech Wood, which formed part of the Castle estate, to the main route from Invergordon to Alness. It is likely that the path pre-dates the railway, which was opened in March 1863
From the American gardens at Invergordon Castle, (now taken over by the Golf Club) you could walk down through a beautiful Beech Wood, down a hill, commonly known as The Bull's Hill...down to the shore, via the Donkey Bridge.
I think these small bridges that have railway lines over them are named donkey bridges because nothing larger than a donkey could fit under them. Alness has one at the front of Teaninich Street and it is also called a donkey bridge. It is much lower than Invergordon's though. I may be wrong, and any info on the origin of this type of bridge would be greatly appreciated.
