New York—New York's transportation system, along with banks, ad agencies and other businesses that depend on it, remains paralyzed by the impact of Hurricane Sandy.
All 209 miles of the city's subway system remained closed today, as the Metropolitan Transportation Authority is working to pump thousands of gallons of sea water out of the tubes and tunnels. Railyards in Harlem, the Bronx and Brooklyn's Coney Island were flooded.
While the MTA said emptying the subway tubes and tunnels may take four days, no service can be restored until equipment damaged by salt water is replaced. All 10 tunnels in lower Manhattan connecting the borough to Brooklyn, Queens and New Jersey were flooded and are out of service.
The New York Stock Exchange, Nasdaq and CME Group in Chicago are closed today.
Meanwhile, Hurricane Sandy has grounded more than 13,000 flights across the Northeast and elsewhere, according to
FlightAware. Airports in the metropolitan New York area were open, but airlines were not operating.
