The Boring Company (TBC) proposes to construct and operate an alternative, high speed transportation option for travel between Washington, District of Columbia and Baltimore, Maryland.

The proposed action consists of the construction of approximately 35.3 miles of parallel, twin underground tunnels (Main Artery tunnels), extending from 55 New York Avenue NE in Washington, D.C. to parking facilities for Oriole Park at Camden Yards located at 333 Camden Street, Baltimore, MD. The underground alignment for the Main Artery tunnels would generally parallel beneath public rights-of-way for US 50/New York Avenue NE in Washington, D.C., the Baltimore-Washington Parkway, MD 295, and Russell Street in Baltimore, MD.

Electronic, battery-powered, autonomous electric vehicles (AEVs) traveling at speeds of up to 150 miles per hour would transport passengers through the Main Artery tunnels between the termini in Washington, D.C. and Baltimore, MD. In addition to the Main Artery tunnels, project components would include two Loop Stations at the termini points, 20-70 ventilation shafts distributed along the corridor, and four launch shaft sites for tunnel boring machines. At least one of the launch sites would be ultimately converted into a maintenance terminal for AEVs.
