Our realistic scenario uses $15M per mile: 30 to 65% more than TBC's announced price, and the project holds up even at full conventional rates. https://velotunnelquebec.com/en/articles/panama-tunnel-vision-challenge.html https://velotunnelquebec.com/en/articles/panama-tunnel-vision-challenge.html Thu, 09 Jul 2026 12:00:00 -0400 In 2026, The Boring Company offered to build a tunnel for free — pedestrians and bikes included. The City of Panama proposed a cycling tunnel under the canal (the "Canal Underline"), still under study in spring 2026. What the "Tunnel Vision" contest proves for our project. https://velotunnelquebec.com/en/articles/boring-company-2026.html https://velotunnelquebec.com/en/articles/boring-company-2026.html Wed, 01 Jul 2026 12:00:00 -0400 A record 3.7 km bore in a single run, a deal signed in Dubai, machines supervised from Texas and a target of roughly US$2.5M per kilometre: an update on the technology behind our project. https://velotunnelquebec.com/en/articles/bergen-bike-tunnel.html https://velotunnelquebec.com/en/articles/bergen-bike-tunnel.html Wed, 01 Jul 2026 09:00:00 -0400 Since 2023, cyclists in Bergen, Norway, cross the Løvstakken mountain through a tunnel designed for them — the longest in the world. Full-scale proof that the concept works, and several lessons for the Québec project.
