a network of roadways important to the country's economy, defense, and mobility. The freeway carried 168,200 vehicles on average between I-75 and Chene Street in Detroit, which is the peak traffic count in 2015, and it carried 12,554 vehicles immediately west of the Blue Water Bridge in Port Huron, the lowest traffic count in 2015. As the state trunkline highway closest to the lake shore in these areas, I-94 carries the Lake Michigan Circle Tour south of Benton Harbor–St. Joseph and the Lake Huron Circle Tour in the Port Huron area. Sections through the Detroit area are named the Detroit Industrial and Edsel Ford freeways. I-94 in the state is either a four- or six-lane freeway for most of its length; one segment in the Detroit area has up to 10 lanes total near the airport. Southwestern Michigan I-94 enters Michigan from Indiana south of New Buffalo. The freeway runs northeasterly through rural Michiana farmland in the southwestern corner of the Lower Peninsula and parallels the Lake Michigan shoreline about inland. I-94 traverses an area just east of the Warren Dunes State Park as the freeway runs parallel to the Red Arrow Highway, a former routing of US 12 named after the 32nd Infantry Division (Red Arrow Division). The freeway crosses its companion highway south of St. Joseph; Red Arrow turns northward carrying the business loop for Benton Harbor and St. Joseph (Business Loop I-94, [BL I-94]). The Interstate curves further inland to bridge the St. Joseph River near Riverview Park. East of Benton Harbor, I-94 meets the other end of BL I-94 at an interchange where US 31 merges onto the freeway. East of the Southwest Michigan Regional Airport, I-94/US 31 meets the southern end of I-196; US 31 departs the I-94 freeway to follow I-196, and I-94 continues its course away from Lake Michigan. South of Coloma, the trunkline turns eastward and roughly follows the Paw Paw River on a course that takes it south of Watervliet and Hartford. Between the latter two cities, the freeway transitions from northeastern Berrien County into western Van Buren County. It curves around and between Lake Cora and Threemile Lake near the junction with the northern end of M-51. About further east, I-94 crosses M-40 south of Paw Paw. Continuing eastward, the Interstate runs through Mattawan before entering western Kalamazoo County. In Texas Township, the freeway enters the western edges of the
