New York Today: Water Main Break Updated 7:59 a.m. Good morning on this cloudy, foggy Wednesday. Beware of delays - a water-main break in Greenwich Village is causing a messy commute. We will be updating regularly throughout the morning on the problems. For now, here's what you need to know: Several subway lines are affected. Some streets are closed to traffic. Here is a guide from the M.T.A. on the service changes. No D between Atlantic Avenue and 34th Street. No B between DeKalb Avenue and the Bronx. No M between 36th Street in Queens and Essex in Manhattan. M trains are running on the F line between 36th Street in Queens and 34th Street in Manhattan. Delays on the N and Q in both directions. Delays on the southbound J and Z. F running on the E line from West Fourth to Jackson Heights. C skipping local stops between Canal and 59th Street. Pipes burst near Fifth Avenue and 13th Street shortly after midnight, and it took five hours to bring the flood under control. "The water has been pumped out of the tracks and crews are in the process of removing debris" an M.T.A. spokeswoman said at 7:40 a.m. Once debris has been removed we will run a test train through the area and determine it's safe to resume normal service. Fifth Avenue remains closed between 14th and 13th Street. Rails: Some delays on L.I.R.R. Check L.I.R.R., Metro-North or New Jersey Transit status. Roads: Look out for fog and black ice north of the city. Areas of dense fog till 9 a.m. Clouds and a few stray sun rays all day long, with a high of 47. Down to 36 tonight. You probably know plenty by now about traffic patterns on the George Washington Bridge, given the scandal over lane closings ordered by Gov. Chris Christie's administration. But what about the New York side of the bridge? It's that spot where several roadways meet in Upper Manhattan, then twist around, curly-straw style, and squeeze out two decks of gridlock. The passage here isn't easy, either. "It's a mess," the NY1 traffic reporter Jamie Shupak told us. I would say coming in from New Jersey is worse, but not by a lot. This winter, emergency repairs caused delays of hours for outbound traffic on at least three separate occasions. On normal days, drivers can expect accidents, stalled vehicles, potholes - "and delays of at least 30 minutes every rush hour, every single day," Ms. Shupak said. Behind the delays is not a human but the Cross Bronx Expressway, consistently one of the most-congested roadways in the nation, "mainly because everyone is headed to the George." On New Jersey's side, traffic-bound commuters may watch the largest free-flying flag in the world - a 60 by 90 foot Old Glory hangs over its bridge tower. New York has the Little Red Lighthouse below, and the 32-story Bridge Apartments above, which overlook any number of accidents daily. What are your experiences on either side of the bridge? Let us know in the comments, or on Twitter, with #NYToday.

Lightning zap Rangers, 2-1. Panthers pounce on Islanders, 4-2. But the Devils beat the Canadiens, 4-1. Five years ago today, there was a plane in the Hudson. A U.S. Airways jetliner carrying 155 people touched down on the water after losing power in both engines. Ferries and emergency boats pulled off a quick rescue. The pilot, Chesley B. Sullenberger - who has since been immortalized in books and a TV documentary, and lent his name to a cocktail - will float more peaceably off our shores this afternoon. He will take a brief ferry ride with survivors and the ferry crews who rescued them. So tonight, make yours a Sully.
