Interstate 96 (I-96) is an east–west Interstate Highway that runs for approximately entirely within the Lower Peninsula of the US state of Michigan. The western terminus is at an interchange with US Highway 31 (US 31) and Business US 31 (Bus. US 31) on the eastern boundary of Norton Shores southeast of Muskegon, and the eastern terminus is at I-75 near the Ambassador Bridge in Detroit. From Grand Rapids through Lansing to Detroit, the freeway parallels Grand River Avenue, never straying more than a few miles from the decommissioned US 16. The Wayne County section of I-96 is named the Jeffries Freeway from its eastern terminus to the junction with I-275 and M-14. Though maps still refer to the freeway as the Jeffries, the portion within the city of Detroit was renamed by the state legislature as the Rosa Parks Memorial Highway in December 2005 in honor of the late civil rights pioneer. There are four auxiliary Interstates as well as two current and four former business routes associated with I-96.
Grand River Avenue originated as an Indian trail before Michigan statehood. It later was used as a wagon road across the state. The roadway was included in the State Trunkline Highway System in 1919 as M-16 and later the United States Numbered Highway System as US 16. Construction of a freeway along the length of the corridor was proposed in the 1940s, and included as part of the Interstate Highway System in the mid-1950s. This construction was started in 1956 and initially completed across the state to Detroit in 1962. The proposed route for the Jeffries Freeway in Detroit was moved in the 1960s; it was built in the 1970s. I-96 was completed on November 21, 1977, in the Detroit area, closing the last gap along the route. Since then, additional interchanges and lanes have been added in places to accommodate traffic needs.
Route description
I-96 is maintained by the Michigan Department of Transportation (MDOT) as a segment of the larger State Trunkline Highway System. In 2011, the department's traffic surveys showed that on average, 201,200 vehicles used the highway daily between 6 and 7 Mile roads in Livonia. Near Norton Shores, 20,638 vehicles did so each day between Airline and Fruitport roads. These are the highest and lowest counts along the highway, respectively. As an Interstate Highway, all of I-96 is included in the National Highway System, a network of roads important to the country's economy, defense, and mobility. In addition, the highway in Detroit has been named the Rosa Parks Memorial Highway by the Michigan Legislature to honor the civil rights pioneer Rosa Parks. The segment from Livonia west to I-275 is the Jeffries Freeway, named for a former mayor of Detroit, Edward Jeffries.
Muskegon to Grand Rapids
I-96 begins at a three-quarter cloverleaf interchange with US 31 northeast of the Muskegon County Airport in Norton Shores, near Muskegon. At the starting terminus, the highway has a grassy median and two lanes in each direction as it travels southeasterly through rural Muskegon County. The freeway is paralleled by Airline Highway in an area with a mix of fields and residences as far as Fruitport. I-96 bypasses that village to the north and east before crossing into Ottawa County at Fruitport Road. After a distance of about in the county, the trunkline reaches Nunica. The highway crosses the Crockery Creek and turns eastward toward Coopersville. The freeway runs parallel to the Grand River, about to the north. Near Ironwood Drive, I-96 turns southeasterly again and goes through Marne.
Beyond Marne, I-96 passes the western end of M-11 and crosses into Kent County, curving around a rest area for the eastbound lanes. The freeway runs eastward through a light industrial area of the suburb of Walker as it enters the Grand Rapids metropolitan area. At the interchange with Alpine Avenue, M-37 merges onto the freeway and the two run concurrently past the studios for WZZM-TV with its iconic weatherball, a sphere above the ground that uses colored lights to display a weather forecast. Adjacent to the studios are the ramps from eastbound I-96 to southbound US 131 and from northbound US 131 to westbound I-96. These ramps mark the northern end of I-296, an unsigned auxiliary Interstate Highway designation applied to them and the US 131 freeway south to downtown Grand Rapids. I-96 turns northeasterly past a commercial area to a three-quarter cloverleaf interchange that provides all of the other connections with US 131 next to a crossing of the Grand River.
