 Both of these plans, however, were shelved in a 1951 study, citing the extreme costs of building a modern highway through very unforgiving terrain as the primary reason.The study recommended that the northern terminus be moved to Fairplain just outside Ripley and that the southern terminus remain in Princeton.The study also suggested that the highway be constructed as a two-lane facility rather than a four-lane highway, with provisions for future widening when funding became available.
