Improvements to the Stockton area interstate system include redesignation of several freeways as interstate routes throughout the area.

Interstate 9 would upgrade a major central valley artery to interstate standards from Red Bluff to the Mettler Wye south of Bakersfield. Interstate 9 would travel along the SR-99 alignment south of Sacramento. In downtown Sacramento the route would replace the northeast leg of Business route 80 (SR-51). The route continues cosigned with I-80 through Roseville, and then would turn north on State Route 65 towards Marysville. from there it continues to the SR-65 and SR-70 split meeting with future (I-509) and turns northward on a new bypass routing east of Marysville. The route then joins the SR-70 corridor through Oroville and then jumps over to the SR-99 corridor on SR-149. The route continues up SR 99 until it meets again with I-5 near Red Bluff.

Interstate 109 would replace the existing SR 4 freeway that connects I-80 at Hercules to SR-99 (Future I-9) in Stockton. This highway passes thru Antioch and Concord along the way. This long spur freeway provides another vital interstate route number into the Bay Area and continuity with the I-9 system.

Interstate 205 would be extended eastward to connect to SR-99 (future I-9) in Manteca.
