The Kinsol Trestle, also known as the Koksilah River Trestle, is a wooden railway trestle located on Vancouver Island north of Shawnigan Lake in the Canadian Province of British Columbia. It provides a spectacular crossing of the Koksilah River.
Completed in 1920, its dimensions measure 44 m (144 ft) high and 188 m (617 ft) long, making it the largest wooden trestle in the Commonwealth of Nations and one of the highest railway trestles in the world.
It was built as part of a plan to connect Victoria to Nootka Sound, passing through Cowichan Lake and Port Alberni, when forestry had gained some ground on Vancouver Island and a more efficient way to transport the region's huge, old-growth timber was needed. It was not built, as some mistakenly believe, to serve any nearby mines. It was named after the nearby Kinsol Station which, in turn, took its name from a nearby mining venture grandiosely named “King Solomon Mines”, a very small mining venture that produced 18 t (19.8 short tons; 17.7 long tons) or 18,000 kg or 39,683 lb of copper and 6,300 g (203 ozt) of silver (from 254 t or 280 short tons or 250 long tons of ore - hardly enough to fill 3 rail cars) over the period 1904-1907 .
The line was started in 1911 by the Canadian Northern Pacific Railway (CNoPR) and while it was designed by engineers, it was built by local farmers and loggers, with investment funds from the Canadian Western Lumber Company, which was the largest lumber company in the world at that time. The trestle was never completed by the CNoPR, and the line only reached Youbou before construction was terminated. The CNoPR was taken over by Canadian National Railways in 1918, and its line and the trestle were completed in 1920 as part of the "Galloping Goose" rail line. The last train to cross the Kinsol was in 1979, and the trestle was abandoned 1 year later.
