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 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 segregationist 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 Jr. Boulevard. The Capitol Loop, also internally numbered Connector 496,
