The Boring Company, a Elon Musk company...
The Boring Company is an American infrastructure and tunnel construction services company founded by Elon Musk. Its current and proposed projects are designed for loop intra-city transit systems although the company has stated that the Hawthorne test tunnel can support Hyperloop R&D and that current tunnels are being built so they could support eventual transition to Hyperloop-based transportation on longer inter-city routes
