The World’s most expensive individual landslide

Probably. :rofl:

I drive by here almost every day. This happened in April, 32 years ago.

The April 1983 Thistle debris slide, probably the world’s most expensive individual landslide, and the lake it formed by damming the Spanish Fork River severed three major transportation arteries: U.S. Highways 6/50 and 89, and the main transcontinental line of the Denver and Rio Grande Western Railroad (D&RGW). The D&RGW spent about $40 million ($69 million) to reestablish its line outside the devastated area, mostly to construct a twin-bore tunnel about 900 m long that bypassed the landslide and lake . ... These indirect losses from the Thistle landslide disaster may exceed the direct costs. Thus, total costs (direct and indirect) of this slide were probably on the order of $400 million ($688 million). Although there were no casualties as a result of the Thistle slide, it ranks as the most economically costly individual landslide in North America, and probably in the world.

Lake formed by landslide (and new road works)



Here you can see the 'street view' of the slide and the massive cut through Billie's Mountain for the new road
