Roads to the Future formerly had Interstate I-895 on this list for the Route 895 Pocahontas Parkway, because that was the designation that had been planned for it, but since the Commonwealth Transportation Board decided to designate it as Virginia State Route 895 when it opened in 2002, it was deleted from this list. The highway is built to full Interstate standards, and it may receive an Interstate designation sometime in the future, but the highway cannot be considered an Interstate highway at the present. In the above Route 895 Roads to the Future article, there is a section Route Number Designation for Route 895 that discusses in detail why that it should be designated as Interstate I-895.
