It houses members of Sigma Phi Society, hosts communal dinners, organizes small concerts, and offers tours for other students and members of the public, welcoming thousands of visitors a year. The Thorsen House can be toured throughout the week on an informal basis; one can simply knock on

216-499: A $ 300 million renovation program, which would include completely replacing the bridge deck. Painting of the bridge takes seven years, and when painting of the bridge is complete, it begins again. The current painting project began in 1999 and was expected to take 20 years to complete because the lead-based paint needs to be removed, incurring additional disposal requirements. The bridge celebrated its 150 millionth vehicle crossing on September 6, 2009. Five workers died during

324-497: A 4.2-magnitude earthquake occurred on Saturday, May 2, 2015, shortly after noon, about five miles south of Galesburg, Michigan (9 miles southeast of Kalamazoo ) in central Michigan, about 140 miles west of Detroit, according to the Colorado-based U.S. Geological Survey 's National Earthquake Information Center . No major damage or injuries were reported, according to then-Governor Rick Snyder 's office. State government

It cannot continue to grow as it ought with clumsy and inadequate ferries for any portion of the year. By 1928, the ferry service had become so popular and so expensive to operate that Governor Fred W. Green ordered

864-660: A landmark during the day to safely guide the passenger ships and freighters traveling the Great Lakes (see: lighthouses in the United States ). The state's rivers are generally small, short and shallow, and few are navigable. The principal ones include the Detroit River, St. Marys River, and St. Clair River which connect the Great Lakes; the Au Sable , Cheboygan , and Saginaw , which flow into Lake Huron;

972-563: A long distance between the ends of the state. Ironwood , in the far western Upper Peninsula, lies 630 miles (1,010 kilometers) by highway from Lambertville in the Lower Peninsula's southeastern corner. The geographic isolation of the Upper Peninsula from Michigan's political and population centers makes the region culturally and economically distinct. Frequent attempts to establish the Upper Peninsula as its own state have failed to gain traction. A feature of Michigan that gives it

1080-625: A nearly bloodless siege in 1812. A U.S. attempt to retake Detroit resulted in a severe American defeat in the River Raisin Massacre . This battle, still ranked as the bloodiest ever fought in the state, had the highest number of American casualties of any battle of the war. Michigan was recaptured by the Americans in 1813 after the Battle of Lake Erie . They used Michigan as a base to launch an invasion of Canada, which culminated in

1188-430: A permanent community there would strengthen French control over the upper Great Lakes and discourage British aspirations. The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent (about 0.85 acres (3,400 m ), the equivalent of just under 200 feet (61 m) per side) and named it Fort Pontchartrain . Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of

Automobile production became the major industry of Detroit and Michigan, and permanently altered

4212-455: The steel superstructure. Construction, staged using the 1939–1941 causeway, took three and a half years (four summers, no winter construction) at a total cost of $ 100 million and the lives of five workers. Contrary to popular belief, none of them are entombed in the bridge. It opened to traffic on schedule on November 1, 1957, and the ferry service ceased on the same day. The bridge was formally dedicated on June 25, 1958. G. Mennen Williams

4320-437: The 1830s, Michigan had 30,000 residents, more than enough to apply and qualify for statehood. On November 1, 1935, the U.S. Post Office issued a commemorative 3-cent stamp celebrating the 100th anniversary of Michigan statehood. Michigan's statehood, however, wasn't officially established until January 26, 1837, but since the campaign for statehood actually began in 1835, Michigan chose to hold its centennial celebration in 1935,

4428-478: The 1880s. At the time, the Straits of Mackinac area was becoming a popular tourist destination, especially following the creation of Mackinac National Park on Mackinac Island in 1875.
