glenfinnan viaduct

The iconic solid concrete bridge has 21 spans of 15 metres over a distance of some 380 metres and a height of 30 metres which makes it Britain’s longest bridge of its type.  Building started in 1897 and was completed enough to be used by 1898 at a cost of £18,904.  The official opening was 1st April 1901.  The viaduct was built by Robert MacAlpine who was known as Concrete Bob due to his innovative use of concrete and was ultimately completed by his son, Malcolm.

Now the structure is probably just as famous as “The Harry Potter Bridge” due to its inclusion in the movies of the young wizard travelling to Hogwarts on the Hogwarts Express. There is a steam train running during the summer months which crosses the viaduct 4 times a day between Fort William and Mallaig so visitors can plan their very own Harry Potter Experience.
