I-66 Westbound Washington DC. to Gainesville, VA

Took a drive down I-66 Westbound from Washington DC. to Gainesville, VA a long way from completing the new road expansion. Still a lot of lane changes more heading westbound than when I was going eastbound but not as bad as it was before. Interstate 66 begins at I-81 near Middletown, Virginia and ends in Washington DC. In VA. I-66 Goes 74.8 miles until you cross over the Roosevelt Bridge into DC. for another 1.6 miles until you come to the end of I-66 for a total of 76.4 miles. This was done in real time.
