Interstate 69 (I-69) is a part of the Interstate Highway System that currently runs from Indianapolis, Indiana, to the US–Canadian border at Port Huron, Michigan. In Michigan, it is a state trunkline highway that enters the state south of Coldwater and passes through the cities of Lansing and Flint. A north–south route from the Indiana–Michigan border to Lansing, it changes direction to east–west and continues to Port Huron and the US–Canadian border. In Flint, I-69 is also known as the Chevrolet-Buick Freeway, as a tribute to the Flint automotive industry. A 30-mile (48 km) stretch of I-69 between Flint and Perry is designated as the Pearl Harbor Memorial Highway. Until 2002, US 27 was concurrent with I-69 from the Indiana–Michigan state line north to the Lansing area.
