As of the 2010 census, the township had a population of 90,173, making it Michigan's second largest township and eleventh largest community.  Canton is ranked as 96th highest-income place in the United States with a population of 50,000 or more.  Canton Township is also consistently ranked as one of the safest cities in the United States, as well as in the state of Michigan.  In 2015, the township was ranked as the 29th safest city in America.  Canton is one of Michigan's fastest growing communities. M-14 is an east–west state trunkline highway in the southeastern portion of the US state of Michigan.  Entirely freeway, it runs for 22.250 mi to connect Ann Arbor with Detroit by way of a connection with Interstate 96 (I-96).  The western terminus is at a partial interchange with I-94 west of Ann Arbor.  From there, the freeway curves around the north side of Ann Arbor and runs concurrently with US Highway 23 (US 23).  East of that section, M-14 passes through woodlands and fields in Washtenaw County.  In Wayne County, the freeway returns to a suburban area of mixed residential neighborhoods and light industrial areas.  It crosses two different rivers and a pair of rail lines as it approaches Detroit's inner suburbs, where it terminates at an interchange between I-96 and I-275. Washtenaw County ( ) is a county located in the U.S. state of Michigan.  As of the 2010 census, the population was 344,791.  The county seat is Ann Arbor.  The county was founded in 1822 and organized as a county in 1826. Ann Arbor Charter Township is a charter township of Washtenaw County in the U.S. state of Michigan.  As of the 2010 census, the township population was 4,361.  The city of Ann Arbor is adjacent to the township on the south and west sides.  Small islands of the township also lie within the boundaries of the city of Ann Arbor.  Under a 1994 boundary agreement with the city of Ann Arbor, eventually all of these islands will be permitted to be annexed by the city. Interstate 94 (I-94) is a part of the Interstate Highway System that runs from Billings, Montana, to the Lower Peninsula of the US state of Michigan.  In Michigan, it is a state trunkline highway that enters the state south of New Buffalo and runs eastward through several metropolitan areas in the southern section of the state.  The highway serves Benton Harbor–St. Joseph near Lake Michigan before turning inland toward Kalamazoo and Battle Creek on the west side of the peninsula.  Heading farther east, I-94 passes through rural areas in the middle of the southern Lower Peninsula, crossing I-69 in the process.  I-94 then runs through Jackson, Ann Arbor, and portions of Metro Detroit, connecting Michigan's largest city to its main airport.  Past the east side of Detroit, the Interstate angles northeasterly through farmlands in The Thumb to Port Huron, where the designation terminates on the Blue Water Bridge at the Canadian border. M-36 is a state trunkline highway in the Lower Peninsula of the US state of Michigan that runs in a west–east direction from Mason to Whitmore Lake.  The trunkline connects US Highway 127 (US 127) south of Lansing and US 23 north of Ann Arbor.  The highway connects several smaller communities in the rural areas along its route.  M-36 also runs concurrently with two other roadways, sharing pavement with M-52 and County Road D-19.  According to traffic surveys in 2010, between 650 and 15,300 vehicles used the highway on average each day. US Highway 23 (US 23) is a United States Numbered Highway that runs from Jacksonville, Florida, to Mackinaw City, Michigan.  In the US state of Michigan, it is a major, 362 mi , north–south state trunkline highway that runs through the Lower Peninsula (LP).  The trunkline is a freeway from the Michigan–Ohio state line near Lambertville to the city of Standish, and it follows the Lake Huron shoreline from there to its northern terminus.  Serving the cities of Ann Arbor and Flint, US 23 acts as a freeway bypass of the Metro Detroit area.  Overall, the highway runs through rural areas of the state dominated by farm fields or woodlands; some segments are urban in character in the Ann Arbor, Flint and Tri-Cities areas.  The section from Flint north to Standish also carries Interstate 75 (I-75) along a concurrency that includes a segment that carries almost 70,000 vehicles on a daily basis. M-132 was the designation of a former state trunkline highway in the Lower Peninsula of the US state of Michigan near Ann Arbor.  The highway, commissioned in 1929, connected Ann Arbor and Dexter to the northwest along present-day Dexter–Ann Arbor Road.  The roadway was turned back to local control around 1960. There are currently eight business routes of Interstate 94 (I-94) in the US state of Michigan.  These business routes connect I-94 to the downtown business districts of neighboring cities.  These eight routes are all business loops which bear the Business Loop I-94 (BL I-94) designation.  These loops are former routings of I-94's two predecessors in Michigan: US Highway 12 (US 12) or US 25.  The westernmost BL I-94 runs through the twin cities of Benton Harbor and St. Joseph along the former routing of US 12 and US 31/US 33 that now includes a section of the Lake Michigan Circle Tour in the state.  The loops in Kalamazoo, Battle Creek, Marshall, Albion, and Jackson were also formerly segments of US 12 which were later designated as separate version of Business US Highway 12 (Bus.  US 12) through their respective cities before becoming BL I-94s in 1960.  The route of the business loop through Ann Arbor was previously US 12 and then later M-14 before receiving its current moniker.  The BL I-94 through Port Huron was previously US 25 and then Business US Highway 25 (Bus.  US 25). Ann Arbor is a city in the U.S. state of Michigan and the county seat of Washtenaw County.  The 2010 census recorded its population to be 113,934, making it the sixth largest city in Michigan.
