Elon Musk's Boring Company Prepares to Tunnel Under San Antonio

The arrival of the Prufrock-5 machine advances site preparation for the campus connection, but equipment delivery is not permission to begin tunneling.
Preparations for Morgan’s Inclusion Tunnel in San Antonio have advanced with the arrival of the Prufrock-5 tunnel-boring machine. The delivery was announced on October 14; this week’s coverage should not be read as evidence of a second arrival or a newly started excavation.
The proposed approximately 0.8-mile connection is intended to link Morgan’s campus facilities. Final approvals remain an important condition before the underground work can proceed.

Explore insights →Equipment on site is a preparation milestone
Delivering a tunnel-boring machine demonstrates a physical commitment to the worksite. It enables assembly, positioning and other preparatory activity, but does not by itself establish that the machine has begun its drive.
The distinction matters when assessing photographs of the site. A machine being transported, lifted or prepared can look like the start of tunneling even though the excavation sequence has not yet been authorized. The next decisive milestone would be an expressly confirmed launch, supported by the necessary approvals.
A campus connection, not a regional transit network
The Inclusion Tunnel is a defined campus project. Its length and intended connection should not be combined with separate discussions about much longer regional tunnel systems.
Keeping those scopes apart avoids assigning speculative network costs, ridership or construction schedules to this project. The current update concerns equipment and readiness at Morgan’s, not approval of a wider intercity transport scheme.
What remains unresolved
The supplied reporting identifies TxDOT approval as still pending. The reviewed material does not establish a final authorization date, the start of the tunneling drive or an opening date for the connection.
For construction tracking, the key sequence is approval, confirmed launch, excavation progress and eventual fit-out and readiness for operation. Each is a separate milestone. A delivery announcement should not be used to skip over the regulatory stage.
The existing members-only profile retains the project team, earlier worksite reporting and construction timeline. It provides a place to record an approval or launch when one is confirmed, without rewriting preparation as completed tunneling.
