Five of Scotland's lesser known bridges

This 18th century multi-arched bridge in Moray can be hard to spot at first, as it is surrounded by so much vegetation.

The eerie bridge has been neglected for so long that it is considered 'at risk' by the Buildings at Risk Register for Scotland.

The picturesque bridge has a mural passage and is unusual looking for bridges of its time. Curiously, on the north-west corner of the bridge, a doorway opens which leads on to a small room.

The bridge is on private land at the Letterfourie Estate.

Overtoun Bridge, near Dumbarton in West Dunbartonshire, Scotland, has gained infamy for the number of dogs that have jumped to their death from it.

Built in 1895, and designed by civil engineer H.E.Milner, hundreds of pooches have reportedly jumped from 18inch-thick granite walls and died after hitting rocks 50 feet below.

Overtoun also boasts a baronial castle, built in 1895 by James White, the father of Lord Overtoun, as an ornate religious symbol.

Often described as one of the most beautiful bridges in the world, Kylesku Bridge was built In 1984 to replace a ferry service in the West of Sutherland.

Designed to compliment the stunning scenery in which it is set, the bridge - which has won several awards - was opened by the Queen.

Its setting means you may even spot some wildlife - including seals, otters and eagles, that can be found in this area.

The original Mousemill Brig was built of wood and was first mentioned in 1587.
The stone bridge standing today seems to have been substituted about 1649.

Early in the 19th century the modern bridge was built a few yards away and the old one allowed to fall into decay.

So named because it does in fact lead to nowhere.

Built out of reinforced concrete, the bridge has nine arches and lies beyond the Tolsta Village on the Isle of Lewis.

It was built as part of the ill fated route intended to make up part of Lord Leverhulme's (who owned the Isle of Lewis from 1918-1923) new road to Ness.

But nowadays when you walk over the bridge you are met by a rough path which runs for a mile of so along a scenic - but incredibly boggy - route across the cliff tops of the local area.
