Improvements to the Sacramento 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 305 would replace the western leg of the capital city freeway signed as US 50 and business 80. This route is already approved and is an unsigned Interstate route that connects I-80 in West Sacramento to SR-99 at the east sacramento interchange.

Interstate 509 would travel north of sacramento from I-5 at the SR-99 split northward continuing in northbound SR-70 to the future I-9 corridor at the 65/70 split in Olivehurst.
