Because we already paid for it - that’s how come we have a right to use it.
You are certainly a disagreeable person. I said take another route and you say: “Actually there aren’t any. Look at an f’in map instead of spouting of (sic) your ignorant mouth.” What kind of a comment is that to make to a FRiend?
For your info I did the research and found that Interstate 66 in Virginia traverses 74.84 miles east-west from I-81 in Warren County to the District of Columbia border (Potomac River) in Arlington County. I-66 serves the towns and cities of Strasburg, Front Royal, Manassas, Fairfax, Vienna, Falls Church, Arlington, and the District of Columbia.
I-66 was built near to and parallel to existing major interregional highways; VA-55 from I-81 to Gainesville, and US-29 from Gainesville to the District of Columbia. Virginia I-66 had one planned Interstate spur route, I-266, which was cancelled in 1977. http://roadstothefuture.com/I66_VA_Desc.html
Parallel roads show up on a street map and unless they closed up those parallel and existing major inter-regional highways/roads, which I seriously doubt, how about saving your venom for your own self.
