I-94 (Edsel Ford Freeway) runs east–west through Detroit and serves Ann Arbor to the west (where it continues to Chicago) and Port Huron to the northeast. The stretch of the current I-94 freeway from Ypsilanti to Detroit was one of America's earlier limited-access highways. Henry Ford built it to link the factories at Willow Run and Dearborn during World War II. A portion was known as the Willow Run Expressway. The I-96 freeway runs northwest–southeast through Livingston, Oakland and Wayne counties and (as the Jeffries Freeway through Wayne County) has its eastern terminus in downtown Detroit.
