I work in road construction. I could maybe see this being feasible in highly localized critical areas, but this kind of road method can’t become commonplace. Canada just has too many roads.

Maybe a bridge along the DVP in Toronto that always has bad ice accidents, or a major bike arterial path, but the numbers don’t make sense for anywhere else. If a road/bridge is truly that bad for accidents, the Municipality is likely cheaper to redesign the approach/descent angles or change the speed limit rather than try this.

I note they don’t talk about how much road a 50 or 60 ton system would be able to serve, compared to the Vancouver budget, or what maintenance costs are on a system that size. The article they link to discussing the system costs is specifically looking at the costs of a BTES system for buildings/complexs.

Out of curiosity, what kinds of things would a federal government have done to make you feel this sense of pride you’re looking for? Are there any governments anywhere that have accomplished that task?

Even then, that would not make that businessman the most knowledgeable in the world about medicine
