are tied to the Caltrans "Route 99 Corridor Enhancement Master Plan"; this document posits that when and if Interstate status is conferred, the route will be designated either I-7 or I-9. In August 2005, with the passage of that year's SAFETEA-LU federal transportation legislation, SR 99 from Wheeler Ridge to Stockton and beyond to Sacramento was designated as High Priority Corridor 54, the California Farm-to-Market Corridor; this legislation also designated that corridor as a future segment of the Interstate System. Interstate 42 The Fixing America's Surface Transportation Act (FAST Act) added the US 70 corridor between Garner and Morehead City, North Carolina, to the Interstate system by defining it as, first, High Priority Corridor #82 and subsequently designating it as a future Interstate. The Regional Transportation Alliance expected this corridor to be called Interstate 46 or another suitable designation. At a meeting in La Grange, North Carolina, on March 17, 2016, the Super 70 Corridor Commission recommended that the designation of Interstate 50 be sought for the US 70 Interstate corridor. The rationale for the I-50 numerical selection was cited as a number not in conflict with either an existing Interstate designation or currently applied to a U.S. Highway within North Carolina. This recommendation was forwarded to NCDOT for submission to AASHTO. For the AASHTO Special Committee on U.S. Route Numbering meeting in May 2016, NCDOT proposed I-36 for this route. However, AASHTO instead designated the route as Interstate 42. In March 2022, the Federal Highway Administration designated the Clayton Bypass and the Goldsboro Bypass, which have been built to Interstate Highway standards, formally as Interstate 42. As of May 2022 signage has not been installed designating the new route. Other proposals Interstate 67 Interstate 67 has been a proposed number for at least three highways. Indiana has proposed using the I-67 designation for the freeway upgrade of US 31 currently under construction between Indianapolis and South Bend, possibly continuing northward via the US 31 freeway to Benton Harbor, Michigan, and going northward from there along existing I-196 to Grand Rapids. The Indiana Senate unanimously passed a resolution calling for federal funding for this proposal and the I-67 designation in 2003. Meanwhile, Indiana expedited the upgrading of three major sections on US 31 between Indianapolis and South Bend including the Kokomo Bypass. This was done using funds received through the 2006 Major Moves deal. Such a proposal would put I-67
