Siyeh Creek Culvert, Spanning Siyeh Creek at Going-to-the-Sun Road, West Glacier, Flathead County, MT

Significance: The Siyeh Creek Culvert is one of approximately seventeen prominent masonry and concrete structures on Going-to-the-Sun Road in Glacier National Park. The 51-mile stretch of scenic road is significant as a unique engineering accomplishment of the early twentieth century, and as the first product of a 1925 cooperative agreement between the National Park Service and the Bureau of Public Roads. As with other structures on the road, the culvert's designers used a masonry arch facade in an attempt to make it blend with the park scenery.
