Virginia to Grand Island KOA/ Niagra Falls

Thanks. leaving from Va Beach but your answer confirmed what others have said about going the 79 to 90 route which was my main concern.

Where in Virginia are you starting from? If on the Western end, I would go I-77 to US-19 to I-79 to I-90 to I-190 (exit 53) over the Grand Island bridge to the KOA. Regardless of where you start from, you'll have to get on the I-190 and go over the Grand Island bridge to Exit 18A (Grand Island Blvd.) to the campground.
