I stopped at AAA the other day for information and tour books. While there, I asked if there was anyway that I could get up-to-date travel information about road closings, and there is. Here is the website, I'm using Pa. for an example.
www.511pa.com
This 511 gives you road closings due to construction, weather related closing, parades & etc.
You can use 511 for any state, just change it to the state that you are interested in.
It is helping us plan our trip to the rally.
