In 1923 the A829 ended at a dead end in Kinlochleven
Listed in the 1922 Road Lists as Carnach - Kinlochleven, the A829 was built during World War I by German prisoners of war as an access route to the new aluminium works at Kinlochleven. The works had started construction in c.1902 but until 1919 when the road was completed the only access was via Loch Leven, the Old Military Road over the Devil's Staircase and onto Fort William, or a very rough coastal path along the north shore of the loch via Callert. The new road finally gave the residents of this new town a permanent, usable route to the outside world!
The B863 (former A829) on the northern side of Loch Leven
During the early 1920s the path via Callert was slowly improved so that by 1930 the full route around the loch was the A829. This then changed in 1935 when, with a permanent road link now available, it was decided to re-route the A82 via Kinlochleven and so avoid the ferry. The A829 number has lain dormant ever since, despite one erroneous map marking it as the short spur on the north side of the Ballachulish Ferry. As far as can be told this was a misprint for the A828.
When the Ballachulish Bridge was opened in 1975 the A82 was routed that way instead and the former route of the A829 became the B863, so see that page for more information.
