According to Sawyer Merritt (@SawyerMerritt), The Boring Company President Steve Davis announced that the company aims to reduce tunneling costs to about $10 million per mile within 2–5 years, and ultimately to $3–$4 million per mile, leveraging automation and advanced AI-powered construction technologies. This represents a dramatic cost reduction compared to traditional subway tunneling, which can reach $1–$5 billion per mile in cities like New York. The integration of AI for real-time project management, robotics, and predictive maintenance creates significant business opportunities for AI startups and suppliers in the infrastructure and construction sectors. These advancements could reshape the economics of urban transportation infrastructure, enabling more cities to consider underground transit solutions at highway-level costs (source: @SawyerMerritt, Nov 24, 2025).
