Summarize this article for a 10 year old
Interstate 69 (I-69) is a part of the Interstate Highway System that will eventually run from the Mexican border in Texas to the Canadian border at Port Huron, Michigan. In Michigan, it is a state trunkline highway that enters the state south of Coldwater and passes the cities of Lansing and Flint in the Lower Peninsula. A north–south freeway from the Indiana–Michigan border to the Lansing area, it changes direction to east–west after running concurrently with I-96. The freeway continues to Port Huron before terminating in the middle of the twin-span Blue Water Bridge while running concurrently with I-94 at the border. There are four related business loops for I-69 in the state, connecting the freeway to adjacent cities.

Predecessors to I-69 include the first M-29, US Highway 27 (US 27), M-78 and M-21. The freeway was not included on the original Interstate Highway System planning maps in the mid-1950s, but it was added in 1958 along a shorter route. Michigan built segments of freeway for the future Interstate in the 1960s, and the state was granted additional Interstate mileage in 1968 to extend I-69 north and east to Flint. Later extensions in 1973 and 1987 resulted in the modern-day highway. The first freeway segment designated as I-69 in Michigan opened in 1967, and the last was completed in 1992, finishing Michigan's Interstate System. US 27 previously ran concurrently with I-69 from the Indiana–Michigan state line north to the Lansing area, but this designation was removed in 2002.
