Interstate 475 (Michigan)

I-475 starts at a partial interchange with I-75 in Grand Blanc Township, southwest of Grand Blanc. From this start at exit 111, the freeway proceeds northward through a suburban residential area next to a baseball field complex. As I-475 continues northward, it has an interchange with Hill Road near the Crestwood Memorial Gardens cemetery and several commercial properties. North of the Maple Avenue underpass, the freeway crosses into the suburb of Burton where it runs for about before crossing into the city of Flint. The freeway then curves around to the northeast near Thread Lake, crossing over Saginaw Street. I-475 follows the western shore of the lake as it turns northward to run into downtown Flint. South of the four-level stack interchange with I-69, North of this interchange, the freeway runs more northwesterly as it skirts the eastern edge of downtown Flint. Near the campus of the University of Michigan–Flint, I-475 curves to run parallel to the Flint River before crossing it next to an industrial area. There is an interchange complex on the northwest side of the river that provides access to Stewart Avenue and M-54 (Dort Highway). I-475 then runs north and northwesterly North of Carpenter Road, the freeway exits the city of Flint and enters Genesee Township. The Interstate turns to the west to cross into Mount Morris Township before meeting an interchange for Saginaw Street. There is one more interchange for Clio Road before I-475 terminates at a full interchange at exit 125 on I-75 and US Highway 23 (US 23). As an Interstate Highway, I-475 has been listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility. ==History==

A freeway along the I-475 corridor was proposed in the 1950s. The 1955 General Location of National System of Interstate Highways, an early proposal for what would become the Interstate Highway System, contained an inset of the proposed freeways in and around the Flint area, including a loop route freeway near the downtown area. Designated as part of the Interstate Highway System in 1957, I-475 construction was funded by the federal government. I-475 was first opened to traffic in the early 1970s. The first section was built between I-75/US 10 northward to M-21/M-78. The second section was built from I-75/US 10/US 23 to Business M-54 (Bus M-54) along the north side of town. These two sections were opened on November 9, 1973, and September 26, 1974, respectively. ==Memorial highway designations==

I-475 has carried two different memorial highway designations in its history, the Buick Freeway and the UAW Freeway. David Dunbar Buick was a Scottish-born immigrant who moved to Detroit with his parents at the age of two in 1856–1857. He quit school to supplement the family's income after his father's 1860 death. In the 1880s, he was a plumbing supplier in the Detroit area, inventing a process that created a cheaper white bathtub. Buick produced a method for permanently coating cast iron with vitreous enamel, which allowed the production of white baths at lower cost. He later sold his plumbing business and the patents to American Standard. Using the profits from this sale, Buick started working on gasoline engines, and later automobiles. He eventually moved his operations from Detroit to the Flint Wagon Works. William C. Durant managed the fledgling Buick Manufacturing Company, making it the number one car-building company in the country by 1908. Durant later built on the foundation of Buick's company to create General Motors. In honor of Buick's contributions to Flint's manufacturing base, the Flint City Commission proposed naming I-475 after Buick. The freeway passed by the city's Buick plant and many of the employees would use the new freeway on their commutes to work. The Michigan Legislature passed Concurrent Resolution 22 in 1969 to add the name. A local politician wanted to honor not just the automotive pioneers in Flint but the workers that worked in the plants. Since the UAW came to maturity in Flint as a result of the strikes, it was the appropriate location for a memorial highway designation. In 1980, the Michigan Legislature passed House Concurrent Resolution 583, renaming Flint's east–west freeway (I-69) the "Chevrolet–Buick Freeway" and I-475 the "UAW Freeway". I-475 was dedicated with its new name on Labor Day 1981. Public Act 142 of 2001 consolidated the memorial highway designations of the state. In passing this act, the Michigan Legislature expanded the Chevrolet–Buick Freeway to encompass all of I-69 in Genesee County; the act also restored Buick's name to I-475. ==Future==

The Genesee County Board of Commissioners has proposed to MDOT that I-475 should be connected to US 23 in the southern part of Genesee County. The board approved a study to investigate the economic impact of such an extension. The study will also examine how such an extension will impact an existing intermodal transportation hub at Bishop International Airport and a rail terminal being built at the former Buick City complex. Proposals for the freeway connection have been around since the late 1990s, but they were indefinitely postponed in 2011. ==Exit list==
