Nashville puts a price on rock tunnelling — and our estimate stays more conservative
US$240 to $300M for 13 miles of twin tunnels in Nashville, in limestone the same age as Québec's rock: about $9 to $11.5M per bored mile. Our realistic scenario uses $15M — 30 to 65% more than The Boring Company's announced price — and the project holds up even at full conventional rates.
Tunnel Vision Challenge: The Boring Company validates the bike tunnel — and Panama proves it
In 2026, The Boring Company launched a global contest offering to dig 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 that proves for our project.
