1. Nobody closed any lanes down on the George Washington Bridge. This might come as a shock to everyone -- including Freepers -- who have accepted this blatantly false media report as fact, but it's true. If anyone had shut down the George Washington Bridge -- one of the busiest sections of roadway in the country (the bridge carries 14 lanes of I-95 between New Jersey and New York City) -- then this would have been a national story within minutes of the bridge closure.
2. What really happened in September 2013 is that two of the three entrance ramp that feed onto the bridge from the local streets of Fort Lee were closed. From what I can tell, other traffic wasn't disrupted and may have even flowed better across the bridge that day.
3. Related to Item #2 ... The information presented in that Wikipedia article indicates that closing the local lanes from Fort Lee to the George Washington Bridge PERMANENTLY is probably a good idea. This is because the two lanes from Fort Lee don't feed directly onto the bridge. They feed into specific lanes at the bridge's toll plaza that aren't open to the rest of the motorists who get to the bridge from all the major highways that feed into it.
If there was a political side to this, it's probably driven by a long-running battle among various state transportation agencies who are trying to figure out why Fort Lee residents get their own dedicated toll lanes on the eastbound (NYC-bound) bridge, while the rest of North America -- including converging highways such as I-80, I-95, US Route 46, State Route 4, and the Palisades Parkway -- has to deal with the inevitable daily bottlenecks at the bridge.
