Macdonald & Lawrence Timber Framing Ltd.

Thought to be the longest and highest surviving structure of its kind in North America, the highest in the British Commonwealth - now, possibly, in the world - the Kinsol Trestle over the Koksilah River was an ambitious undertaking even for experienced railway construction men.

Reaching 187 metres (614 feet) long, 38 metres (147 feet) high - as tall as a 12-storey building - and gently arcing six degrees from south to north, it was built entirely by hand of timber on concrete footings. The result of these mostly anonymous pioneers' handiwork is an Erector kit of such mammoth proportions that modern-day visitors are invariably awed.
