Can't say this enough: DO NOT TAKE THE WILSON BRIDGE THIS WEEKEND! (June 9-12)

Sorry for the yelling! Please, if you're planning on coming up I-95 from the south any time between Friday and Monday, go around the DC beltway to the west. John Adams provided instructions at the link above. The Wilson Bridge is undergoing construction and there will be back-ups miles long. This press release (pdf) has more information.
