From the City of Hoboken:
“United Water construction crews are on the scene near 13th Street and Garden Street to make repairs to a 6″ water main.
The main has been shut off to make repairs, so residents on Garden Street between 12th St and 13th St as well as 13th Street between Bloomfield Street and Park Avenue are expected to be without water service.”
Additionally, traffic is blocked at various spots along Garden Street.
UPDATE: As of 2:30 p.m., service has been restored.
