New Orleans awaits update on Elon Musk's proposed tunnel

• The announcement was met with befuddlement by residents in the city famously below sea level.
• Weeks later, the city learned that Mayor Helena Moreno applied for the project, according to The Times-Picayune.

Zoom in: The proposal calls for a mile-long tunnel that would connect the Ernest N. Morial Convention Center to the Hyatt Regency near the Caesars Superdome, the paper reported.

• Teslas would transport passengers.
• The Boring Company says it will pay for the due diligence, and if the project is feasible, it says it'll fund and build it.
• The company has a working tunnel in Las Vegas and another one under construction in Nashville. See how it works.

The intrigue: The Boring Company in late March said it had "great initial meetings" in New Orleans but hasn't provided any other public updates.

• It's unclear how far the due-diligence process has progressed. The Boring Company did not respond to a request for comment Tuesday. Neither did the mayor's office.
• There haven't been recent updates about the Dallas proposal either.
• Meanwhile, Baltimore scrapped its project after the Ravens withdrew their application.
