Interstate 94
Highway system

There are currently eight business routes of Interstate 94 (I-94) in the US state of Michigan. These business routes connect I-94 to the downtown business districts of neighboring cities. These eight routes are all business loops which bear the Business Loop I-94 (BL I-94) designation.

Benton Harbor–St. Joseph business loop[edit]

Business Loop Interstate 94
Location: Benton HarborSt. Joseph
Length: 10.705 mi[1] (17.228 km)
Existed: November 2, 1960[2]–present

Business Loop Interstate 94 (BL I-94) is a 10.7-mile (17.2 km) state trunkline highway and business loop that runs from I-94 through the downtowns of Benton Harbor and St. Joseph. The highway begins at exit 23 on I-94 in Lincoln Township where it runs along Lakeshore Drive, passing through the community of Shoreham. This section of the loop is part of the Lake Michigan Circle Tour (LMCT). BL I-94 briefly runs concurrently with M-63 along Main Street in downtown St. Joseph before crossing the St. Joseph River on Ship Street to Benton Harbor; the LMCT concurrency ends where BL I-94 separates from M-63. From there it follows Main Street through downtown Benton Harbor to the eastern terminus at exit 33 on I-94 in Benton Township. The easternmost leg of the loop, from Urbandale Avenue easterly to I-94, is a limited-access divided highway; it features an unusual intersection with Crystal Avenue which is constructed identically to a diamond interchange, albeit without a grade separation between BL I-94 and Crystal Avenue.[3][4]

The highway through the downtowns of Benton Harbor and St. Joseph was a part of US Highway 12 when the United States Numbered Highway System was created in late 1926. US 31 was also routed concurrently through the area.[5] The US 33 designation was later added to US 31 from the state line northward to US 12 in St. Joseph in 1937.[6][7] On November 2, 1960, the I-94/US 12 freeway opened around the Benton Harbor–St. Joseph area,[2] and the former route of US 12 through downtown was renumbered BL I-94. By the next year, US 33 was extended along BL I-94/US 31, and the eastern end of BL I-94 was converted to a divided highway.[8] In 1962, US 31 was rerouted out of downtown Benton Harbor and St. Joseph to follow a new freeway east of Benton Harbor, removing it from BL I-94/US 33.[9][10] US 33 was truncated in 1986,[11] removing it from BL I-94 and replacing it with M-63 the following year when signage was updated.[12][13] The Great Lakes Circle Tours were approved by the Michigan Department of Transportation (MDOT) and its counterparts in Minnesota, Ontario and Wisconsin.[14]

Kalamazoo business loop[edit]

Business Loop Interstate 94
Location: Kalamazoo
Length: 11.090 mi[1] (17.848 km)

Interstate 94 Business Loop or BL I-94 is a Michigan highway looping for 11.21 miles (18.04 km) from the I-94 freeway through downtown Kalamazoo. It partially follows the routing of a former BUS US 12. The highway begins at Exit 74 on I-94 in Portage where it runs concurrent with US 131 until it intersects with BUS US 131 (Stadium Drive) at exit 36 in Oshtemo Township. From there it follows BUS US 131 and M-43 through downtown Kalamazoo. At an interstection between BL I-94/M-43 (Kalamazoo Avenue) and King Highway, BL I-94 turns along King Highway to its eastern terminus at I-94's exit 81.

BL I-94 is freeway from the western terminus concurrent with US 131 to the western junction with BUS US 131, and it is expressway from the eastern terminus northwesterly to the corner of King Highway and Amvets Memorial Parkway in Kalamazoo at a junction with M-96 (OLD US 12).

On December 7, 1959, the I-94/US 12 freeway is opened on the south side of Kalamazoo. This marks the beginning of BUS US 12 in the Kalamazoo area, The highway was routed along the former US 12 on Stadium Drive to a junction with M-43 (Michigan Avenue), BUS US 12 then followed Michigan Avenue to King Highway back to I-94/US 12. BUS US 12 is signed temporarily along 9th Street in Oshtemo from Stadium Drive southerly to I-94/US 12 starting on January 6, 1960. Later in 1960, BUS US 12 is redesignated as BL I-94 in preparation to move the US 12 designation to the US 112 corridor.

On December 16, 1963, the US 131 freeway was opened on the west side of Kalamazoo. Along with the creation of BUS US 131 along a portion of the BL I-94 routing, BL I-94 was rerouted along the US 131 freeway on the west end back to I-94. The section of Stadium Drive west of US 131 and the 9th Street routing was removed from BL I-94.

Kalamazoo and the newly built Michikal avenues were transferred to state jurisdiction on October 4, 1965. To smooth out traffic patterns downtown, Michikal Avenue was built as a connector between Kalamazoo and Michigan avenues. Kalamazoo and Michigan avenues are used as a pair of one-way streets downtown. Kalamazoo and Michikal were then signed as westbound BL I-94 from Stadium Drive to Michigan Avenue while Main Street and Michigan Avenue continue to serve eastbound traffic.

Battle Creek business loop[edit]

Business Loop Interstate 94
Location: Battle Creek
Length: 13.978 mi[1] (22.495 km)

Business Loop Interstate 94 is a highway looping from the I-94 freeway through the downtown Battle Creek. It follows the routing of a former BUS US 12. It is 13.60 miles (21.89 km) long.

The highway begins at exit 92 on I-94 where it runs concurrent with M-37 until the intersection of Dickman and Helmer roads. It then runs along Dickman Road until it intersects with I-194/M-66 in downtown Battle Creek. It then follows Main St. northwest ward to Hamblin Ave, where it turns northward, then it follows Michigan Avenue eastward soon gaining a concurrency with M-96 to its eastern terminus at I-94's exit 104.

In 2015, the route will again have another change in routing as the U.S. Government has plans to expand the Air National Guard Base. After that change, the highway will still begin at Exit 92, head northward to Columbia Ave. east to Helmer Rd. north to Dickman Rd. east. Part of the existing road will be eliminated to allow for a bigger blast radius for ammunition testing.

The road was commissioned as BUS US 12 on November 12, 1940 and converted to BUS I-94 in 1960.

Marshall business loop[edit]

Business Loop Interstate 94
Location: Marshall
Length: 5.707 mi[1] (9.185 km)

Interstate 94 Business Loop or BL I-94 is a 5.52 miles (8.88 km) highway looping from the I-94 freeway through downtown Marshall. It follows the routing of a former BUS US 12. The highway begins at exit 108 on I-94 where it runs concurrent with I-69 until it intersects with Michigan Avenue at exit 36 near downtown Marshall. From there it is follows Michigan Avenue and Partello Road to its eastern terminus at I-94's exit 112.

The original routing of BUS US 27 was commissioned in 1960 with the completion of the I-94/US 12 freeway bypass of Marshall. It followed US 27 (Kalamazoo Avenue) to Michigan Avenue. From there, BUS US 12 followed the current routing of BL I-94 along Michigan Avenue and Partello Road. It was redesignated as BL I -94 in late 1960 as a preparation to move the US 12 designation to its current routing along the former US 112.

The portion of BL I-94 along US 27 (Kalamazoo Avenue) became BUS US 27 with the completion of the I-69/US 27 freeway bypass on December 15, 1967. BL I-94 was rerouted and cosigned with BUS US 27 along Michigan Avenue and the new freeway on the west end. On January 11, 2001. BL I-94 inside the city of Marshall was designated what is now a Pure Michigan Historic Byway.

Albion business loop[edit]

Business Loop Interstate 94
Location: Albion
Length: 4.520 mi[1] (7.274 km)

Interstate 94 Business Loop or BL I-94 is a 4.42-mile (7.11 km) highway looping from the I-94 freeway through downtown Albion. It follows the routing of a former BUS US 12. The highway begins at exit 121 on I-94 where it runs along Eaton Avenue, Austin Avenue, Superior Street, and Michigan Avenue until the highway intersects I-94 exit 124 near downtown Albion.

August 15, 1960 marked the opening of the I-94/US 12 freeway in Calhoun County. At this time, Eaton Avenue was transferred to state control, marking the debut of BUS US 12 in Albion. BUS US 12 used Easton Avenue and other portions of the former US 12 through Albion. Later that year, BUS US 12 became BL I-94 in preparation to move the US 12 designation south to replace US 112. The highway was concurrently designated with M-99 from Superior Street to the eastern terminus. M-199 intersected BL I-94 north of the M-99 junction and ran along a portion of the former US 12.

Jackson business loop[edit]

Business Loop Interstate 94
Location: Jackson
Length: 10.274 mi[1] (16.534 km)

Business Loop Interstate 94 is a 10.08-mile (16.22 km) highway looping from the I-94 freeway through downtown Jackson. It follows the routing of a former BUS US 12. It runs concurrently with M-60 between the western terminus in Blackman Township at exit 136 on I-94 and the Michigan Avenue exit. Through downtown Jackson, it is also concurrent with BUS US 127/M-50 between North East Street and Airline Highway. Its routing along Michigan Avenue is a former routing of US 12 before the construction of I-94 and the move of US 12 to the US 112 corridor in Michigan.

The US 12 bypass of Jackson was partially completed in 1951. US 12 turned south along US 127 (Lansing Road) at the end of the freeway to connect back to the existing routing of US 12 through the west end of town. The former routing along Ann Arbor Road and Michigan Avenue into downtown to US 12/US 127/M-50/M-60 became BUS US 12 at this time.

The bypass of Jackson was extended west to Parma in 1953. BUS US 12 was rerouted along US 127/M-50/M-60 on West Avenue to connect back to US 12. The last routing change to BUS US 12 came on July 29, 1958 with the opening of the M-60 bypass of Jackson. BUS US 12 was extended back along Michigan Avenue to the new freeway west of town in Blackman Township and northerly to a new western terminus at I-94/US 12. The designation as BUS US 12 lasted until late 1960 when the State Highway Department redesignated the BUS US 12 routings in Michigan as BL I-94 routings. This allowed the US 12 designation to be removed from the completed I-94 freeway and moved to replace the US 112 corridor farther south in Michigan.

In 1964, several changes were made to the business routes in the central business district of Jackson on a trial basis. The jurisdictional transfers to affect this changes were not officially made until November 30, 1967. Eastbound BL I-94 traffic was shifted off Michigan Avenue along Blackstone Street to Washington Avenue From there it ran along Washington to Francis Street and back to Michigan Avenue The westbound traffic was shifted north at Mechanic Street to Pearl Street On Pearl traffic continued until turning south at Blackstone back to Michigan Avenue When the permanent jurisdictional transfers were made, eastbound traffic, joined by southbound BUS US 127/M-50, still used Blackstone and Washington. This leg was extended to Louis Glick Highway/Airline Drive. BUS US 125/M-50 traffic turned south, and BL I-94 traffic turned north. Eastbound traffic turned north at Louis Glick back to Michigan Avenue. Louis Glick Highway was specifically built for these changes.

A set of connector streets was built in 1969 to streamline the flow of traffic further resulting in the last changes to the BL I-94 routing in Jackson. Eastbound traffic is redirected to the connector on Michigan Ave just east of Third Street. This connector curves south then east to Washington Avenue near First Street. Louis Glick Highway is extended west from Blackstone curving south to merge into Michigan.

In 2012, the eastern terminus of the business route was shifted easterly to follow Ann Arbor and Sargent roads to exit 145 off I-94; as a result, the former partial interchange between I-94 and Ann Arbor Road which formerly served as the business route's eastern terminus was obliterated.

Ann Arbor business loop[edit]

Business Loop Interstate 94
Location: Ann Arbor
Length: 8.436 mi[1] (13.576 km)

Business Loop Interstate 94 (BL I-94) is a business loop running from the I-94 freeway through downtown Ann Arbor. It starts at exit 172 on I-94 near on the western side of the city and follows Jackson Road easterly through a residential area and under I-94 before passing through a commercial area next to Veterans Memorial Park. East of the mall, the business loop runs east-northeasterly along Jackson Road through residential areas to a Y-intersection with Dexter Road and Huron Street. BL I-94 follows Huron Street eastward into downtown Ann Arbor. At the intersection with Main Street, Business US Highway 23 (Bus. US 23) turns onto Huron Street, and the two designations run concurrently. The business loop passes to the north of University of Michigan's Central Campus and then turns southward through it on Washtenaw Avenue. near Forest Avenue at the edge of campus, BL I-94/Bus. US 23 turns southeasterly through residential neighborhoods. At the intersection with Stadium Boulevard, Washtenaw Avenue turns more easterly and crosses County Farm Park. East of the park, BL I-94/Bus. US 23 runs through a commercial area out to US 23. At exit 37 on US 23, Bus. US 23 ends and BL I-94 turns southward along US 23. The business loop follows the freeway southward through a residential area on the edge of Ann Arbor and ends at exit 180 on I-94.[15][16]

Washtenaw Avenue facing east

The business loop follows the former routing of US 12. This routing was first designated as M-14 in 1956 when US 12 was moved to a freeway bypass to the south of town.[17][18] I-94 was first designated by the middle of 1960 along the US 12 freeway,[19][20] and a new BL I-94 designation was created by the middle of the next year. BL I-94 followed M-14 from the Jackson Road interchange to Main Street along Jackson Road and Huron Street. At Main Street, BL I-94 turned along US 23 on Huron Street, Washtenaw Avenue and Carpenter Road back to I-94/US 12.[20][21] The US 23 freeway was finished on November 2, 1962.[22] BL I-94 was rerouted on the east end to follow the new US 23 freeway, returning the Carpenter Road alignment to local control. Bus. US 23 replaced US 23 along Huron Street and Washtenaw Avenue in the city of Ann Arbor at this time.[23] A new M-14 freeway opened on November 16, 1965, removing the M-14 concurrency from the routing.[24][25]

Port Huron business loop[edit]

Business Loop Interstate 94
Location: Port Huron
Length: 8.536 mi[1] (13.737 km)
Existed: 1986[26][27]–present

Business Loop Interstate 94 (BL I-94) is an 8 12-mile-long (13.7 km) business loop serving the cities of Marysville and Port Huron. It starts southwest of Marysville near St. Clair County International Airport at exit 266 on I-94. The highway runs northeasterly along Gratiot Avenue past several businesses near the exit. BL I-94 enters Marysville and passes through the city's downtown area. On the eastern side of the city, the business loop turns northward along Gratiot Boulevard near the St. Clair River. The intersection where the business loop turns is also the northern terminus of M-29. North of Ravenswood Road, BL I-94 splits into the one-way pairing of Military Street (northbound) and Electric Avenue (southbound). This area is mostly residential running along the river. Electric Avenue merges back into Military Street near Beard Street.[28][29]

At the intersections with Oak Street (eastbound) and Griswold Street (eastbound), BL I-69 merges in from those two one-way streets. BL I-69/BL I-94 continues northward along Military Street through downtown Port Huron. The business loop crosses the Black River near its mouth. North of the river. the business loop follows Huron Avenue through the northern side of downtown Port Huron. At the intersection with Glenwood Avenue, BL I-69/BL I-94 turns northwesterly onto Pine Grove Avenue through a residential area on the northern side of the city. The business loop passes under I-94/I-69 at the toll and customs plazas for the Blue Water Bridge. There is a partial interchange to connect the business loop to and from the eastbound direction of the freeway and the toll plaza. North of the freeway crossing, the business loop intersects the southern end of M-25 and turns westward onto Hancock Street for two blocks. Then it turns southward along a connector freeway to terminate at an interchange with westbound I-94/I-69.[28][29]

Before the completion of the freeways in the Port Huron area, the route of the business loop was part of US Highway 25 (US 25). After the freeway was completed in the area, the former route was redesignated Business US 25 (Bus. US 25) in 1964.[30][31] The US 25 designation was decommissioned in 1973, and the former Bus. US 25 through the area was designated as part of an extended M-25.[32][33] In 1986, the BL I-94 designation was created, and the former BS I-69 was extended with it through downtown Port Huron.[26][27]
