Interstate 96 (I-96): Muskegon to Detroit Route, Length and Safety Data

How long is I-96?

The January 2026 FHWA Route Log credits I-96 with 187.05 miles, a figure Interstate Guide repeats, while Wikipedia gives about 192 miles from one end to the other.

The difference comes from lanes I-96 shares with I-69 on the west side of Lansing. The Route Log counts each shared mile under one route only, and its I-96 row notes 5.20 miles on I-69. I-69's Michigan row is the longer of the two, so this page treats those 5.20 miles as booked to I-69 and adds them back to I-96, which gives 192.25 miles for the crash rate. Wikipedia describes the overlap as about 6.5 miles.

I-275 also runs with I-96 between Novi and Livonia in MDOT's reckoning. FHWA ends I-275 at the M-14 junction instead, and the Route Log row for I-96 carries no I-275 note, so no miles are added for that stretch.

Where I-96 starts and ends

The western end is a three-quarter cloverleaf interchange with US 31 in Norton Shores, southeast of Muskegon. At the eastern end in Detroit, I-96 passes its interchanges with I-94 and I-75 and finishes at the ramps to the Ambassador Bridge.

In the Grand Rapids area the freeway shares lanes with M-37 through Walker, meets I-196, I-296, M-6 and M-21, and serves Gerald R. Ford International Airport. Farther east it crosses the Grand River near Portland, joins I-69 on Lansing's west side and skirts the city to the south, leaving downtown to the I-496 loop. After Howell and the US 23 interchange at Brighton comes the I-275, I-696 and M-5 interchange complex in Novi. From the M-14 junction east to the end, the road is the Jeffries Freeway, with separate express and local lanes between exits 180 and 186B in Detroit.

Interstate junctions along I-96

Three main Interstates meet I-96, and two of them are in Detroit. Heading east, the first is I-69, which shares the road with I-96 on Lansing's west side. Near the end, the Jeffries Freeway meets I-94, the Edsel Ford Freeway, at a systems interchange, then reaches I-75, the Fisher Freeway. I-96's own three-digit branches are covered with the auxiliary routes below. I-275, which belongs to the I-75 family, joins the Novi interchange alongside I-696.

Fatal crashes on I-96

Crashes on the I-96 main line killed 96 people from 2020 to 2024, about 19 a year. Over 192.25 route miles that comes to 10.0 deaths a year per 100 miles, just above the network average of 9.5, and I-96 ranks 19th of the 56 routes long enough to rate, with 1 the highest rate. Deaths rose each year from 18 in 2020 to 22 in 2023, then dropped to 16 in 2024, the fewest of the five years.

With the whole road in Michigan, the county counts say more than a state table could. Wayne County, home to the Jeffries Freeway, had 39 deaths, about 41 percent of the total. Livingston County followed with 14, Ionia with 10, Ingham with 8 and Kent with 6.

Traffic is much heavier at the Detroit end. Wikipedia cites 2011 counts of 201,200 vehicles a day between 6 and 7 Mile roads in Livonia and 20,638 between Airline and Fruitport roads near Norton Shores. It also records a fog pileup of more than 200 vehicles near Williamston on January 12, 2005, which killed two people.

Bridges on I-96

The 2025 National Bridge Inventory lists 158 bridges carrying the I-96 main line, all in Michigan. Seven of them rate Poor, about 4.4 percent, and 26 rate Good, which leaves 125 in Fair condition, close to four in five. The median bridge dates to 1962, the year most of the route opened.

The road crosses the Grand River three times, along with the Thornapple, Red Cedar and Huron rivers and Crockery Creek. MDOT's Ionia County rebuild includes work on the Jordan Lake Road bridge, which carries that road over I-96 and so is not among the 158. Interstate Guide cites an MDOT release dated March 31, 2026, which announced bridge improvements and resurfacing at the US 31 interchange in Muskegon County starting April 6.

Tolls on I-96

FHWA's toll facility inventory for January 1, 2023, has no entry for I-96, and a trip from Norton Shores to Detroit pays nothing. The Flex Route between Kent Lake Road and Novi, opened in March 2025, lets traffic use the shoulders as extra lanes at busy times. Wikipedia's account of it mentions no toll.

I-96 auxiliary routes

I-96 has four three-digit offshoots. The longest, I-196 at 80.47 Route Log miles, runs from Grand Rapids through Holland to I-94 near Benton Harbor and was first planned as part of I-96 itself. I-296 is a 2.79-mile link in Grand Rapids between I-96 and I-196; drivers see US 131 signs on it, since the I-296 number is unsigned. I-496 makes an 11.56-mile loop through downtown Lansing. I-696 covers 28.99 miles as a bypass north of Detroit, from I-96 in Novi to I-75 in Royal Oak and I-94 in St. Clair Shores.

How I-96 was built and rebuilt

I-96 replaced US 16, which Michigan dropped in 1962. Early plans had I-96 coming up from Benton Harbor to Grand Rapids on what is now I-196. The two numbers swapped west of Grand Rapids in 1963, and the new signs went up in January 1964.

The first four miles opened on August 1, 1957, the first funded Interstate section in Michigan. By December 12, 1962, all of the route except the Detroit end was open, including the long stretch from west of Lansing to east of Howell (51 miles in Wikipedia, 59 in Interstate Guide). The Jeffries Freeway was built in stages starting in 1970, and its last section opened November 21, 1977. Until then, Grand River Avenue carried a Business Spur I-96 designation into Detroit.

The Ambassador Gateway Project, started February 25, 2008, carried I-96 through to the Ambassador Bridge; Wikipedia dates its completion to September 21, 2012, after lawsuits between MDOT and the bridge's owner. In 2014 MDOT closed seven miles between Newburgh Road and Telegraph Road (US 24) from April 5 to September 21 for a rebuild estimated at $148 million. MDOT's current Ionia County project costs about $130 million for more than 9 miles between Bliss Road and Sunfield Road. Major work began in June 2024 and wraps up for 2026 in late November, with a smaller westbound phase planned for 2027 and completion set for August 2027.

One state means one traveler site: MDOT's statewide map, linked below, covers I-96 from Norton Shores to Detroit, including work zone closures like those in Ionia County. Use it on the day you travel, since the crash data here stops at 2024.
