:Interstate 205 (California)

I-205 begins at the bottom of I-580's eight-lane descent from Altamont Pass into the San Joaquin Valley. Here I-580 turns southeast to a junction with I-5, paralleling the California Aqueduct and Delta–Mendota Canal along the foothills, while I-205 continues east as a six-lane roadway, immediately crossing both waterways. The first interchange is with Mountain House Parkway, formerly Patterson Pass Road, which serves the planned community of Mountain House. Next is a split with I-205 Bus., a business loop that follows 11th Street through Tracy. As I-205 curves east-northeast and back east through the northern part of Tracy, it has interchanges with Grant Line Road (County Route J4 [CR J4] toward Antioch), Tracy Boulevard (CR J13 through downtown Tracy), and MacArthur Drive. After several miles without an interchange, the highway ends at a merge with I-5, where traffic can continue northeast to the junction with State Route 120 (SR 120) near Manteca and then east on SR 120 toward Yosemite National Park or north on I-5 toward Stockton.Google Maps street maps and USGS topographic maps, accessed February 2008 via [http://mapper.acme.com/ ACME Mapper]

As it connects to I-580, I-205 is a frequently-congested major commuter route to the Bay Area.Oakland Tribune, Creative solution OKd to unlock I-205 gridlock, September 30, 2005 Signs on eastbound I-580 instruct travelers to take I-205, SR 120, and SR 99 to reach Modesto instead of using the direct, but non-freeway, route SR 132. I-205 also serves to connect the Bay Area with popular weekend destinations such as Yosemite National Park, Reno, and Lake Tahoe.Les Mahler, Oakland Tribune, Commuters to get break with I-205's expansion, August 1, 2005 The Altamont Corridor Express provides commuters with an alternate route over Altamont Pass to San Jose and San Francisco, the latter through a transfer to Bay Area Rapid Transit.

I-205 is part of the California Freeway and Expressway System{{CAFESystem}} and is part of the National Highway System,{{FHWA NHS map|region=tracy|access-date=September 15, 2017}} a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.{{FHWA NHS}} It is officially designated as the Robert T. Monagan Freeway, after the California legislator who represented the area from 1961 to 1973.{{CA Named Freeways | pages=85, 308}}

When the Department of Engineering laid out the initial state highway system after the state's voters approved a bond issue to pay for it in 1910, they included Route 5, connecting Santa Cruz and Oakland with Stockton via Altamont Pass.{{Cite book |last=Howe & Peters |url=https://books.google.com/books?id=G0w7AAAAMAAJ&pg=PA3 |title=Engineers' Report To California State Automobile Association Covering The Work Of The California Highway Commission For The Period 1911-1920 | year=1921 |location=San Francisco, California |pages=11–16}} San Joaquin County paved the portion near Tracy with asphalt with their own bond issue, passed in 1909, and the state later resurfaced it with concrete.{{Cite book |last=Blow |first=Ben |url=http://archive.org/details/californiahighw00blowgoog |title=California highways; a descriptive record of road development by the state and by such counties as have paved highways |publisher=San Francisco |others=Harvard University |year=1920 |pages=104–105 |language=en |oclc=2577575}} In addition, the new concrete road bypassed Banta, which the old county road had passed through via Banta Road, F Street, and Grant Line Road. Otherwise, the road was relatively direct, coming down from Altamont Pass onto Grant Line Road, following Byron Highway into Tracy and leaving east and northeasterly on 11th Street to the San Joaquin River at the Mossdale Crossing.Automobile Club of Southern California, [http://collections.lib.uwm.edu/cdm/singleitem/collection/agdm/id/200 Automobile Road Map of California], 1917: shows the route via BantaOfficial Automobile Blue Book, [https://books.google.com/books?id=Mt0NAAAAYAAJ Volume Eight], 1918, pp. 75–77: describes the route via BantaRand McNally & Company, [http://members.cox.net/mkpl2/hist/map1926-sf_area.jpg San Francisco and Vicinity], 1926: shows the more direct bypass of Banta {{webarchive |url=https://web.archive.org/web/20071231013124/http://members.cox.net/mkpl2/hist/map1926-sf_area.jpg |date=December 31, 2007 }} The Lincoln Highway Association chose this route in 1913 for their transcontinental highway,New York Times, Lincoln Highway Route Announced, September 14, 1913, p.

Also, the 1970s concrete pavement has been resurfaced with fresh asphalt from the junction of I-5 to due east of the 11th street connector ramp.

The California Department of Transportation (Caltrans) has plans to improve merging distances by constructing auxiliary lanes between the interchanges and to add new interchanges at Lammers Road and Paradise Road.Cheryl Winkelman, Oakland Tribune, Cure for I-580, I-205 in the works, November 26, 2007Mike Martinez, Tri-Valley Herald, Cranes won't halt work, February 27, 2007 Caltrans is also planning to add one high-occupancy vehicle (HOV) lane in each direction between I-580 and I-5.{{Cite web |url=http://www.dot.ca.gov/d10/x-project-i205tracylanewidening.html |title=District 10 - I-205 Tracy HOV 8 Lane Widening |access-date=2018-11-17 |archive-date=2018-11-17 |archive-url=https://web.archive.org/web/20181117063249/http://www.dot.ca.gov/d10/x-project-i205tracylanewidening.html |url-status=dead }}

Interstate 205 Business (I-205 Bus.) is a locally maintained business route. It locally follows 11th Street, the historic four-lane alignment of US 50, through Tracy. The route begins at a split with I-205 west of the city. After passing through downtown Tracy, it curves northeast at a junction with former SR 33, which has been truncated to the south at I-5. The final stretch of I-205 Bus. runs diagonally to a merge with I-5, which comes from the south and continues northeast along the former US 50 alignment. The east end of I-205 Bus. is about {{convert|0.75|mi|km}} southwest of the end of I-205; normally, I-205 Bus. would return to I-205 at both ends, but, here, I-205 and I-205 Bus. both end at I-5.
