State Route 99 (SR 99), commonly known as Highway 99 or, simply, as 99 (without any further designation), is a north–south state highway in the U.S. state of California, stretching almost the entire length of the Central Valley. From its southern end at Interstate 5 (I-5) near Wheeler Ridge to its northern end at SR 36 near Red Bluff, SR 99 goes through the densely populated eastern parts of the valley. Cities served include Bakersfield, Visalia, Fresno, Madera, Merced, Modesto, Stockton, Sacramento, Turlock, Yuba City, and Chico. The highway is a remnant of the former Mexico to Canada U.S. Route 99 (US 99), which was decommissioned after being functionally replaced by I-5 for long-distance traffic. Almost all of SR 99 south of Sacramento is a freeway, and there are plans to complete this part to Interstate Highway standards, as a parallel route to I-5 for Los Angeles–Sacramento traffic. North of Sacramento, the road ranges from a rural two-lane road to a four-lane freeway. ==Route description== SR 99 is part of the California Freeway and Expressway System.〔 〕 From its southern terminus at I-5 in Wheeler Ridge (Wheeler Ridge Interchange) to Sacramento, SR 99 passes through the major cities of the San Joaquin Valley, including Bakersfield, Delano, Tulare, Visalia, Fresno, Madera, Merced, Modesto, and Stockton. A majority of this segment is built to freeway standards, However, there are portions that are a four-lane divided highway, including the section between Merced and Chowchilla that has at-grade intersections. The portion of the highway between Fresno and Modesto has been designated the "100th Infantry Battalion Memorial Highway." The freeway sections connect and serve the agriculture and industry of the California Central Valley, connecting agricultural production with processing and packing businesses. Most of the freeway also parallels the Union Pacific's Fresno Subdivision. In Sacramento, SR 99 first joins with I-80 Business as part of the Capital City Freeway, then runs concurrently with I-5. These SR 99 concurrences are not officially designated by the California Department of Transportation (Caltrans), but mapmakers often show it as such. SR 99 signage had existed along that route for motorists' convenience, but was removed in 2000, and replaced by TO SR 99 signs instead. SR 99 then splits from I-5 in northern Sacramento, and then heads along the eastern segment of the Sacramento Valley through Yuba City, and Chico to its northern terminus at SR 36 near Red Bluff. A majority of SR 99 from Sacramento to Red Bluff is a two-lane highway, while segments in Yuba City and Chico that are built to freeway standards. The portion between Salida and Manteca is designated the "442nd Regimental Combat Team Memorial Highway."〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「California State Route 99」の詳細全文を読む スポンサード リンク
