Business Loop I-75 (BL I-75) is a
In 1919 when the state highway system was first numbered,[7] the main north–south highway through Pontiac was numbered M-10,[8] and it was renumbered to US 10 seven years later when the United States Numbered Highway System was created.[9] By the next year, M-24 was designated from downtown Pontiac northward to Lapeer.[10] M-24 was moved to an eastern bypass of town in 1936, and the former routing in town became M-24A.[11][12] This was redesignated Bus M-24 in 1940.[13][14]
A number of highway designation and routing changes in the Pontiac were made when US 10 was shifted out of downtown to replace
In 1985, the Michigan Department of Transportation (MDOT) received permission from the American Association of State Highway and Transportation Officials to truncate US 10 to Bay City,[20] and when the change was made the following year, US 24 replaced US 10 on Telegraph Road north of Square Lake Road, and Bus. US 10 through downtown was redesignated Bus. US 24, including the segment concurrent with BL I-75.[21][22] Saginaw Street south of downtown was renamed as a northern extension of Woodward Avenue, while Wide Track Drive through downtown was renamed as the Woodward Avenue Loop, both in 2000.[23][24]
The section of BL I-75 that follows Woodward Avenue has a pair of special designations attached to it. In 1999, it was designated by MDOT as what is now called a

Business Loop I-75 (BL I-75) was a
When the state highway system was signposted in 1919,[7] the north–south highway through Saginaw was part of the original M-10.[8] This highway was later redesignated as part of US 23 when the United States Numbered Highway System was created in 1926.[9] US 23 was initially routed on the western side of the Saginaw River through the city, but it was moved in 1929 to run along the eastern side.[33][34] In 1953, the initial eastern bypass of Saginaw was built as a two-lane highway, and the former routing through downtown was redesignated Bus. US 23.[35][36] This bypass was upgraded in 1961 to a full freeway as part of I-75/US 23, and the business loop through downtown was redesignated BL I-75.[29][30] In 1971, I-675 was completed, and BL I-75 was decommissioned through Saginaw. The segments of the business loop that were concurrent with M-13, M-46 or M-81 remained part of those state highways, but the rest of BL I-75 was returned to local control.[31][32]

Business Spur Interstate 75 (BS I-75) is a
When the state highway system was first signposted in 1919,[7] the north–south highway through Bay City was part of the original M-10, and the east–west highway was numbered as part of M-20.[8] When the United States Numbered Highway System was created in 1926, M-10 became part of US 23, although it was routed on the western side of the Saginaw River. The highway was rerouted to the eastern side of the river in 1929.[33][34] By early 1941, US 23 was rerouted to cross the Saginaw River on the southern side of Bay City, and the former routing along Washington Avenue and Midland Street through downtown was renumbered Bus. US 23.[41][42] When the I-75/US 10/US 23 freeway bypass west of Bay City opened in late 1961, the former routing of US 23 was replaced by M-13 and the former Bus. US 23, including connections along the former routing of M-47 southwest and M-20 west of Bay City, were redesignated as BL I-75.[37][38] The BL I-75 designation lasted until 1971 when southern half of BL I-75 was removed, converting the business loop into a business spur; the southern section was renumbered as part of an M-84 extension, and BS I-75 would then run along the section concurrent with M-25 only.[43][44]

Business Loop Interstate 75 (BL I-75) is a
When the state highway system was signposted in 1919,[7] the highway running northwest–southeast through West Branch was numbered M-76 and the east–west highway was M-55.[8] In the early 1970s, M-76 was being converted into a freeway between Standish and the Grayling area. In 1970, the freeway was built as far as the present-day exit 212, and the connection along Cook Road was built to allow M-76 to connect between the new freeway and its former routing.[49][50] The next year, this freeway was completed to bypass West Branch to the south and west. The former route of M-76 through town with the connection along Cook Road was renumbered Bus. M-76.[50][51] Two years later, I-75 was finished in the state,[52] and the M-76 designation was decommissioned. The former Bus. M-76 was redesignated as BL I-75 at the same time.[45][46]

When the state highway system was originally signposted in 1919,[7] the highway running northwest–southeast through Roscommon was numbered M-76.[8] In 1949, M-18 was extended north into Roscommon and then west along M-76.[55][56] During the early 1970s, M-76 was being converted into a freeway to be used as part of I-75. In 1971, I-75 was completed southward from the Grayling area to what is now exit 239. Two years later, I-75 was completed between Roscommon and West Branch,[52] and M-76 between the two communities was decommissioned. At the same time, M-18 was realigned to northeasterly out of Roscommon instead of following M-76 toward Grayling. BL I-75 was commissioned at this time to overlap M-18 from the freeway north into Roscommon and to replace the former M-18/M-76 west of the village to the new freeway.[45][46]

When the state highway system was originally signposted in 1919,[7] the north–south highway through Grayling was part of the original M-14. At that time, M-93 was only a spur from downtown Grayling to the future Camp Grayling.[8] M-14 was later redesignated as part of US Highway 27 (US 27) in 1926.[9] By 1932, M-93 was extended northward through Grayling to the state park.[61] In 1940, M-72 was extended through the Grayling area.[13][41] I-75 in the Grayling area opened in 1961 and, the former routing of US 27 through Grayling northward to Hartwick Pines Road back to I-75 was redesignated BL I-75.[29][30]

A business loop for Indian River was first proposed to the Cheboygan County Road Commission (CCRC) in June 2015. At the time, the road commission had recently placed the bridge on South Straits Highway over the Indian River with a new structure up to Michigan Department of Transportation (MDOT) standards and was repaving the roadway north of the river to the I-75 interchange.[76] The CCRC held a community forum in June 2016, and many local residents and businesses supported the designation at the time.[77] The Tuscarora Township Board and Downtown Development Authority have expressed interesting in paying for the necessary signage should MDOT and the CCRC move forward to apply for the designation from the American Association of State Highway and Transportation Officials. The township board has passed a resolution in support of the BL I-75 designation.[67]
