Interstate 496 (I-496) is an auxiliary Interstate Highway that passes through downtown Lansing in the US state of Michigan. Also a component of the State Trunkline Highway System, the freeway is a loop that connects I-96 to the downtown area. It has been named the R.E. Olds Freeway (sometimes just Olds Freeway) for Ransom E. Olds, the founder of Oldsmobile and the REO Motor Car Company. I-496 runs east–west from I-96/I-69 near the downtown area and north–south along a section that runs concurrently with US Highway 127 (US 127). The trunkline also passes a former assembly plant used by Oldsmobile and runs along or crosses parts of the Grand and Red Cedar rivers. Construction of I-496 started in 1963, and the freeway opened on December 18, 1970. Segments of the freeway south of downtown Lansing were built in the location of a historically black neighborhood. This neighborhood was formed based on the segregations practices of the early 20th century. Community leaders worked for different housing opportunities for the black residents displaced by I-496 rather than fight the freeway. As the trunkline neared completion, competing proposals to name it resulted in two similar, but separate designations applied to I-496. The city originally approved one name in honor of a former mayor. The local historical society proposed that the state name it as a memorial to Olds after the demolition of the Olds Mansion. The city renamed it the Oldsmobile Expressway, the name under which it opened in December 1970. Two years later, the Michigan Legislature restored its preferred name and it has been the Olds Freeway since. ==Route description== I-496 starts at an interchange with I-96/I-69 at that freeway's exit 95 in Delta Township in Eaton County. The freeway runs eastward through suburban areas of the township adjacent to some residential subdivisions. Continuing eastward, there is an interchange for Creyts Road before I-496 angles to the northeast. At the interchange with Waverly Road, I-496 crosses into Ingham County. The freeway then runs parallel to the Grand River. Near a partial interchange with Lansing Road (old US 27〔), the freeway gains a pair of service drives: St. Joseph Street runs one-way westbound on the north side, and Malcolm X Street runs eastbound to the south. The next interchange is for the connection to the Capitol Loop and M-99, both of which run along Martin Luther King Boulevard. The Capitol Loop,〔〔 also internally numbered Connector 496, is a signed connector that provides access to various state government buildings like the Michigan State Capitol. South of this interchange, M-99 connects to the Lansing Car Assembly plant,〔〔 a former facility for Oldsmobile. Continuing eastward, I-496 passes north of the assembly plant complex and south of the central business district. East of a partial interchange with Walnut Street, the freeway passes the Michigan Women's Hall of Fame, which is located on I-496's southern service drive. The south side of the freeway is adjacent to Cooley Gardens near the confluence of the Grand and Red Cedar rivers. I-496 crosses the Grand River downstream from the confluence and meets the eastern terminus of the Capitol Loop. This interchange with Cedar and Larch streets is also a connection to Business Loop I-96 (BL I-96) and Pennsylvania Avenue. St. Joseph Street ends after the connection to Pennsylvania Avenue.〔〔 The main freeway crosses a rail line owned by CSX Transportation. I-496 runs parallel to the north side of the rail line while Malcolm X Street follows to the south as far as the Clemens Avenue overpass. The freeway then crosses into East Lansing near the Red Cedar Natural Area.〔〔 After crossing the city line, I-496 turns southward and merges with US 127. The two highways run concurrently,〔〔 and they cross a line of the Canadian National Railway.〔 The freeway runs along the western edge of the campus of Michigan State University. South of campus, I-496/US 127 crosses back into Lansing and has an interchange with Jolly Road before entering Delhi Township. About two-thirds of a mile (1.1 km) south of Jolly Road, I-496 meets I-96 and terminates; US 127 continues southward as a freeway toward Jackson. Like other state highways in Michigan, I-496 is maintained by the Michigan Department of Transportation (MDOT). In 2011, the department's traffic surveys showed that on average, 61,082 vehicles used the freeway between BL I-96 and the Trowbridge Road interchange south of US 127, the highest traffic count along I-496. West of Creyts Road, 17,600 vehicles did so each day, which was the lowest count along the trunkline. As an Interstate Highway, all of I-496 is listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility. 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「Interstate 496」の詳細全文を読む スポンサード リンク
