Unfortunately, there is no inventory of railway bridges in Canada, making it difficult to accurately determine where the longest or highest active or abandoned bridges are in the country. However, there are some significant bridges in Western Canada of note to compare to those in Alberta. This list is by no means complete so cannot be taken as a comprehensive list of the highest bridges in Western Canada. Many bridges listed in length are not included on this page as height has not yet been established.

Determining bridge height is tricky business as it depends on what you're measuring. At the top end, is it from the top of the rail, the top of the bridge or the roadbed. On the bottom, is it measured from bottom of pier, or, if over a waterway, the average water level or lowest water level, or, if over a ravine, is it to the bottom of the ravine. As a result, records of height of the same bridge can show quite different results. A good example is the original Mountain Creek bridge where records show height somewhere between 136 ft. to 300 ft. or more. So, bridge height ranking indicated in this survey should be seen as relative rather than absolute.

Highest Bridges
Bridges in Alberta highlighted

Lethbridge Viaduct Aug. 2015 - Pettypiece photo1. Lethbridge Viaduct Alberta
- CPR, active, height 96 m (314'), steel trestle
- Built 1908-09 over Oldman River by CPR

- Longest and highest railway bridge in North America (known locally as the High Level Bridge - not to be confused with the High Level Bridge in Edmonton (see below)); longest and highest steel rail trestle in the world; CPR steel trestle 5,331 ft. (1,624 m) long; 314' (95.7 m) high; built 1908-09 over Oldman River on Crowsnest Pass line at cost of $1.3 million using travelling crane built on site; relocated route replaced several wooden trestles including one that was 2,933 ft. (894 m) long, reduced grade and was over 5 miles shorter than original route (built 1898); 33-tower bridge consists of 44-67' spans, 22-99' spans and 1-107' truss span; still in use - approx. 12 trains per day

2. Stoney Creek (Connaught Track) Bridge BC
- CPR, active, height 84 m (275'), steel truss arch bridge 
- Built 1893-94 (strengthened 1929) over Stoney Creek by CPR 
- Length 148 m (486'). Second highest, at 84 m (275') (only Lethbridge Viaduct higher), and most picturesque bridge on CPR located between Revelstoke and Golden on the east slope of the Selkirk Mountains in Glacier National Park near Rogers Pass. Additional truss arches positioned beside the existing 102 m (336') arch strengthened the bridge in 1929. Deck plate girders replaced the original deck lattice girders at the same time in order to handle heavier trains. The bridge replaced the original 1884 timber Howe truss bridge which at the time was the highest timber bridge ever built at approx. 90 m. On a 2.2% grade, the bridge is currently used for mostly lighter eastbound traffic while heavier westbound trains use the newer Stoney Creek (Macdonald Track) bridge built in 1988, 150 m (500') lower in the ravine. Located on the east slope of the Selkirk Mountains on the Mountain subdivision of Revelstoke Division.
