The Boring test tunnel, or Hawthorne test tunnel, is a 1.14 miles (1.83 km) tunnel in Hawthorne, California, for testing hyperloop and "loop-based transportation". Boring of the tunnel started in 2016 and completed in December 2018. The single-bore tunnel was constructed during using a 14-foot (4.2 m) diameter tunnel boring machine, giving a finished 12-foot (3.8 m) internal diameter. The roadway has an asphalt surface, with autonomous vehicle operation of the Tesla Model 3 at speeds of 90 mph (140 km/h) and up to 116 mph (187 km/h) under human control. The Boring Company subsequently built the Las Vegas Convention Center Loop tunnel network.
