A sewage leak just made a section of a major US shipping lane impassable
What happened
The Coast Guard just closed a section of the Gulf Intracoastal Waterway in New Orleans. Ships cannot pass through this area without special permission because of an ongoing sewage leak.
Why it matters
A major shipping lane can be shut down by a sewage leak. This shows how vulnerable critical infrastructure is to mundane failures. It also means local shipping traffic must now find alternate routes or wait for clearance.
The signal
Watch how long this temporary zone remains in effect, and if the Coast Guard issues similar closures for other infrastructure failures.
