I-68   Proposed
Previous I-68's: I-68: In April 1958, VDOT proposed I-68 as the number for current I-495. Andy Vick had a site showing many old proposed routings like this that is no longer available.
Note that the 1957 Route Log assigns VA 88 to the Washington Circumferential Highway. The beltway was also referred to in numerous 1950s CTB references and is on at least 1 Fairfax County planning map as VA 413
