Switzerland’s $2BN Tunnel U-Turn - #183

In this episode, host Fred Mills and guests Luke Bly and Liam Marsh dissect Switzerland’s $2 billion Gotthard road‑tunnel replacement project, explaining its strategic importance for European transport and the technical challenges of building a new tunnel alongside the aging 1980s tunnel. They compare the massive cost to other global megaprojects, discuss the mix of tunnel boring machines and drill‑and‑blast methods, and highlight innovative on‑site concrete plants built in avalanche‑proof caverns. The conversation also touches on related megaprojects like Oklahoma’s new NBA arena and the upcoming ITER fusion reactor, while promoting a competition to win a trip to the ITER site.
