Interstate 94 (I-94) is a part of the Interstate Highway System that runs from Billings, Montana, to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that enters the state south of New Buffalo. It runs east through Detroit to Port Huron before terminating on the Blue Water Bridge at the US–Canadian border.

I-94 is listed on the National Highway System (NHS) for its entire length. The NHS is a network of roadways important to the country's economy, defense, and mobility. I-94 carries 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 ten lanes total near the airport.
I-94 crosses into Michigan south of New Buffalo and parallels the Lake Michigan shoreline about three miles (4.8 km) inland. The freeway runs northeasterly through rural Michiana farmland in the southwestern corner of the Lower Peninsula. I-94 traverses an area just east of the Warren Dunes State Park as the freeway runs parallel to the Red Arrow Highway. I-94 crosses its companion highway south of St. Joseph; Red Arrow turns northward carrying the business loop for Benton Harbor and St. Joseph. The freeway curves further inland to cross the St. Joseph River near Riverview Park. East of Benton Harbor, I-94 meets the Napier Avenue 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, I-94 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 crosses 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 four miles (6.4 km) further east, I-94 crosses M-40 south of Paw Paw. Continuing eastward, I-94 runs south of Mattawan before crossing into western Kalamazoo County.
In Texas Township, the freeway enters the western edges of the Kalamazoo suburbs. South of the campus for Western Michigan University's College of Engineering & Applied Sciences, I-94 intersects US 131 in Portage. That freeway also carries Kalamazoo's business loop northward. Near the Kalamazoo/Battle Creek International Airport, I-94 crosses into the southeastern corner of Kalamazoo before entering Comstock Township. The freeway intersects the eastern end of the business loop at a partial interchange near Morrow Lake in the township. I-94 continues eastward out of the eastern Kalamazoo suburbs. It parallels the Kalamazoo River through the Galesburg area. Before crossing into Calhoun County on the east side of Battle Creek, I-94 has the only driveway on any of Michigan's Interstate Highways for a gate providing access for military vehicles into the Fort Custer Training Center.
I-94 crosses into Calhoun County southwest of the W. K. Kellogg Airport and enters the city of Battle Creek. Immediately east of the county line, the freeway has an interchange with the western end of Battle Creek's business loop. Next to the Lakeview Square Mall, I-94 meets its own auxiliary Interstate in Michigan: I-194. I-94 turns to the northwest to round Beadle Lake, intersecting M-294 before crossing the Kalamazoo River. East of the river crossing, the freeway meets an interchange for M-96, M-311 and the eastern end of the Battle Creek business loop near the FireKeepers Casino in Emmett Township. Turning back eastward, I-94 exits the eastern Battle Creek suburbs and continues to an interchange with I-69 near Marshall; the business loop for Marshall follows I-69 southward.
Into Metro Detroit
Continuing eastward I-94 traverses rural land on the north side of Marshall. The freeway runs north of, and parallel to, the Kalamazoo River through eastern Calhoun County. It angles southeasterly toward Albion before returning to an easterly course on the north side of town. I-94 crosses into western Jackson County before intersecting M-99. From there, it runs generally due east with a jog around Parma on a course to Jackson. West of the Jackson County Airport, the Jackson business loop follows M-60 southward and I-94 travels through the north side of Jackson. North of downtown, US 127 merges in from the north and runs concurrently with I-94 around the city. Southeast of the Michigan State Prison, US 127 departs to the south, and I-94 continues eastward through eastern Jackson County.
The freeway runs north of a racetrack complex in Chelsea next to the M-52 interchange. As I-94 continues easterly, it passes into the western edge of the Ann Arbor area. West of downtown, the M-14 freeway splits off to the northeast, and I-94 turns to the south and southeast to curve around the south side of the city. The freeway passes between the Briarwood Mall and the Ann Arbor Municipal Airport. On the southeastern corner of Ann Arbor, I-94 intersects US 23 and continues around the south side of Ypsilanti. South of that city, the freeway also carries US 12 and crosses the Huron River north of its entry into Ford Lake. I-94 jogs southeasterly around the south side of the Willow Run Airport complex and crosses into Wayne County.
South of Willow Run, I-94 parallels Belleville Lake. East of the lake, it intersects I-275 near the northwest corner of Detroit Metropolitan Wayne County Airport and angles northeasterly through the southwestern Detroit suburbs along the Detroit Industrial Freeway. I-94 passes over the Gateway Bridges over the single-point interchange at US-24/Telegraph Road in Taylor; these bridges were inspired by Super Bowl XL and provide a western gateway to the city. Further east, the freeway intersects M-39 (Southfield Freeway) and passes the Uniroyal Giant Tire in Allen Park. I-94 then turns to the northwest through the Ford River Rouge Complex in Dearborn before turning back easterly on the Edsel Ford Freeway into Detroit.
I-94 crosses Detroit east–west well inland and parallel to the Detroit River. The freeway intersects I-96 (Jeffries Freeway) and M-10 (Lodge Freeway) on the West Side, passing the main campus of Wayne State University before crossing onto the East Side at M-1 (Woodward Avenue). Immediately east of the interchange with I-75 (Chrysler Freeway), I-94 forms the southern border of the Milwaukee Junction district. The Edsel Ford Freeway continues through residential neighborhoods of Detroit's East Side. I-94 turns more northerly, mimicking the shoreline of Lake St. Clair, and exits Detroit for Harper Woods. Just north of the interchange for M-102 (Vernier Road), the freeway crosses 8 Mile Road and enters Macomb County.
North to Canada
Running northward through Macomb County, I-94 meets the eastern end of I-696 (Reuther Freeway) about three miles (4.8 km) north of the county line in St. Clair Shores. The freeway continues to parallel the lakeshore, and travels to the west of Selfridge Air National Guard Base in Harrison Township. I-94 turns back to the northwest at 23 Mile Road at the interchange with M-3 and M-29. North of 26 Mile Road, the freeway exits the northern suburbs and crosses into farmland in The Thumb region.
South of Michigan Meadows Golf Course, I-94 crosses County Line Road and enters St. Clair County. The freeway continues northeasterly as far as Marysville before turning northward near the St. Clair County International Airport. From there, it runs roughly parallel to the St. Clair River. I-94 runs along the western edge of residential areas for Marysville and Port Huron as it continues northward. Immediately west of downtown Port Huron, I-94 intersects with I-69; the two freeways merge and turn first east and then north through an interchange that also features connections to BL I-69.
I-94/I-69 turns back to the east about a mile (1.6 km) north of their confluence to cross the Black River north of downtown. On the eastern bank of the river, there is one final interchange for M-25 and BL I-69/BL I-94 before the freeway reaches the toll and customs plazas for the twin-span Blue Water Bridge. Past these plazas, I-94/I-69 ascends the approach to the bridge which cross the St. Clair River to Point Edward (Sarnia), Ontario. At the international boundary at the center of the river, the I-94 designation jointly terminates with I-69.
The first major overland transportation corridors in the future state of Michigan were the Indian trails. One of these, the St. Joseph Trail, followed the path of the modern I-94. The State Trunkline Highway System was created on May 13, 1913, by an act of the Michigan Legislature; at the time, Division 6 corresponded to the rough path of today's I-94. In 1919, the Michigan State Highway Department (MSHD)[a] signposted the highway system for the first time, and three different highways followed sections of the modern I-69 corridor. The original M-1 ran from the Indiana state line north to Coloma where M-17 connected easterly to Detroit. The third highway was M-19 from Detroit northeast to Port Huron.
On November 11, 1926, the United States Numbered Highway System was approved by the American Association of State Highway Officials (AASHO),[b] and the original route of US 12[c] replaced the highways from the state line northeasterly to Detroit; US 31 overlapped the highway between St. Joseph and Watervliet. The remainder of the future I-94 corridor was served by US 25 between Detroit and Port Huron. The first span of the Blue Water Bridge opened between Port Huron and Point Edward, Ontario, in 1938.
Early conversions to freeways
|Existed:||September 12, 1942–Mid-1956|
The first segments of freeway along the future route of I-94 were added during World War II. Construction on the Willow Run Expressway started in 1941 before the US entered the war. It was opened on September 12, 1942, to provide improved access to Ford's Willow Run bomber plants. The highway was given the M-112 designation at the time. The expressway was extended eastward as the Detroit Industrial Expressway into Detroit; the first section opened in 1943 and the remainder was completed in March 1945. Land acquisition for the Edsel Ford Freeway started in 1945 however uncertainly over funding delayed completion until the 1950s. Originally referred to as the "Crosstown Freeway" the name "Edsel Ford Freeway" was adopted by petition in April 1946. The interchange between the Lodge Freeway and the Edsel Ford Freeway was built 1953 as the first full freeway-to-freeway interchange in the United States. In mid-1956, the M-112 designation was decommissioned and replaced by a rerouted US 12. During the mid-1950s, Detroit Streets and Rails proposed a high-speed rail line in the median of the Willow Run, Detroit Industrial and Edsel Ford freeways; instead of building the rail line, special boarding stations adjacent to dedicated bus lanes in the interchanges along the highway were used.
The first planning maps from 1947 for what later became the Interstate Highway System included a highway along I-94's route in Michigan. This highway was included on the 1955 plan for the "National System of Interstate and Defense Highways" with a proposed spur in the Battle Creek area. The modern I-94 was numbered I-92 between Benton Harbor–St. Joseph and Detroit with I-77 from Detroit to Port Huron in the August 1957 plans.
In April 1958, the MSHD wanted to provide a single number for a more direct routing of a Detroit-to–Chicago freeway; the state proposed rerouting I-94 to replace I-92 in the state, but retained the I-77 designation. On June 27, 1958, AASHO adopted their original numbering plan for Michigan, minus the state's proposed changes. Around the same time, a section of M-146 near Port Huron was converted into an approach freeway for the Blue Water Bridge.
Interstate Highway era
By January 1959, sections of US 12, the Willow Run, Detroit Industrial and Edsel Ford expressways were co-designated as I-94, connecting Ann Arbor to Detroit, along with a bypass of Kalamazoo to Galesburg and a bypass of Jackson. Later that year, additional sections of I-94 were opened, starting with a 10-mile (16 km) section from Hartford to Coloma, then from Paw Paw to Kalamazoo which connected with a segment between Galesburg to Battle Creek. The overall 45-mile (72 km) section from Paw Paw to Battle Creek was dedicated on December 7, 1959. In addition, a new northwest-southeast section of freeway was built east of Ypsilanti to create a more gradual curve in the routing between present-day exits 185 and 186, the original routing of the Willow Run Expressway having followed present-day Wiard Road. Sections of freeway opened in southwestern Michigan in 1960 between the Benton Harbor–St Joseph area and between Jackson and Ann Arbor. In this year Michigan became the first state to complete a border to border toll-free interstate running for 205 miles from Detroit to New Buffalo. A section of 20 miles (32 km) between New Buffalo and Stevensville opened in 1961.
In the beginning of 1962, the US 12 designation was removed from the I-94 freeway. In the process, the designation was transferred to replace the US 112 designation in its entirety. After this transfer, I-94 was no longer concurrent with US 12, except for the Ypsilanti bypass. In 1963 the freeway was extended south of New Buffalo. The freeway ended at M-239. Traffic was diverted down M-239 into Indiana where SR 39 carried traffic the rest of the way to the Indiana Toll Road. A section in the Detroit area between Marysville and Mt. Clemens was also completed. US 25 was used to connect the gap in the freeway between Detroit and Mt. Clemens.
The sections originally designated as the Willow Run Expressway were rebuilt from Rawsonville Road in Belleville to Ozga Road in Romulus starting in 1972. As part of this reconstruction, the segment between Haggerty Road and Ozga Road was widened from four to six lanes, and the eastbound lanes were realigned to facilitate construction of an interchange with Interstate 275, a western bypass of Detroit which was under construction at the time. The Willow Run segment was also resurfaced at this point, as the old road bed did not contain steel mesh. Construction of this interchange also obliterated a partial interchange with Huron River Drive.
On August 16, 1987, Northwest Airlines Flight 255 crashed after attempting to take off from Detroit Metropolitan Wayne County International Airport, killing all but one passenger, Cecilia Cichan, upon exploding at an overpass at Middlebelt Road.
In the 1990s, the Michigan Department of Transportation implemented an "emergency Interstate" system along roads paralleling I-94.
On July 1997, the second span of the Blue Water Bridge opened between Port Huron and Sarnia, Ontario.
The interchange with US 24 (Telegraph Road) had only two bridges and left hand exits were used throughout. This interchange was reconfigured in 2005 to a single-point urban interchange (SPUI) design that was completed in December of that year. A pair of bridges called the Gateway Arch Bridges (alternately "Gateway to Detroit") was incorporated in the new interchange.
In June 2012, after a resolution passed by the Michigan Legislature was signed by Gov. Rick Snyder, a portion of I-94 in Taylor between Inkster Road and Pelham Road was named "Auxiliary Lt. Dan Kromer Memorial Highway" after a 20-year veteran of the Taylor Police Department, who was killed in 2010 while helping motorists who had car trouble.
In 2011, construction was started to widen I-94/I-69 approaching the Blue Water Bridge allowing for dedicated lanes for local traffic and for Blue Water Bridge traffic. The lane configuration changes have confused drivers in the area, especially motorists with outdated GPS devices. So MDOT installed updated signs complete with American and Canadian flags to help prevent drivers from heading to Canada by mistake.
In late 2013, construction began to reconstruct and reconfigure the I-94/I-69 interchange. The project will improve 3.7 miles (6.0 km) of freeway, replace several bridges and ramps and cost $76 million. In June 2014, MDOT closed the ramps from I-69 eastbound to BL I-69 through the interchange until later in the year. The project is slated to be completed in 2015.

There are nine highways related to I-94 in Michigan. The first is the spur into downtown Battle Creek numbered I-194 and nicknamed "The Penetrator" and officially called the "Sojourner Truth Downtown Parkway". This auxiliary Interstate Highway runs for about three miles (4.8 km) to connect I-94 northward into downtown. The other eight highways are business loops of I-94 that connect various cities' downtowns with the main freeway. Unlike I-194, these loops are not freeways. Located from west to east along I-94's routing in Michigan, they serve Benton Harbor–St. Joseph, Kalamazoo, Interstate 94 Business, Marshall, Albion, Jackson, Ann Arbor, and Port Huron.
