Business routes of Interstate 69 in Michigan

There are currently four business routes of Interstate 69 (I-69) in the US state of Michigan. They are all former routings of I-69's predecessor highways, US Highway 27 (US 27), M-78 or M-21.

Coldwater

Business Loop I-69 (BL I-69) is a business loop formed from part of the old US 27 and part of US 12 near and through Coldwater. At the southern end, it begins at exit 10 on I-69 where Fenn Road crosses the freeway. The business loop follows Fenn Road west for about three-quarters of a mile (1.2 km), then curves north to merge with old US 27 (Angola Road). The highway runs northward through farmland south of Coldwater, and after approximately two miles (3.2 km), it enters the city limit at Garfield Road. Once in Coldwater, the business loop follows Clay Street through residential neighborhoods. After another half mile (0.8 km), the highway reaches a fork where Clay Street continues due north and Division Street branches to the northeast; BL I-69 follows Division Street for about another mile (1.6 km) to the main intersection in the city known locally as "the Four Corners." This intersection is where old US 27 intersects US 12 (Chicago Street). BL I-69 turns eastward along US 12 and continues from the Four Corners back to I-69 at exit 13.^[3] The first section of the I-69/US 27 freeway was scheduled to open east of Coldwater in late 1967,^[2] and the business loop appeared on maps the next year.^[4]

The entire highway is in Branch County.

Charlotte

Business Loop I-69 (BL I-69) is a business loop that took over the Business US 27 route inside of Charlotte. It is a surface street for the nearly five miles (8.0 km) of the loop. The trunkline starts just outside of the city of Charlotte at exit 57 and follows Cochran Road The loop travels due north for about 2.5 miles (4.0 km) where it begins a short 0.7-mile (1.1 km) concurency with M-50. That intersection also marks the eastern terminus of M-79. M-50 continues north, and the business loop heads east on Lawrence Avenue for a few blocks. From that point, it veers northeast into Lansing Street and then completes its loop at exit 61.^[5]

The route was first designated Business US 27 after the 1961 completion of a non-freeway bypass, a two-lane highway with limited access on the east of the city. At that point I-69 only existed in the southern parts of Michigan. That freeway was not extended up to the city when the southernmost segment of I-69 was completed in 1967. By 1970, I-69 was completed to Charlotte and at the time US 27 was cosigned with I-69, the bypass being incorporated into I-69. For four years the business loop in Charlotte was not signed as BL I-69, but it was so designated in 1974 and BUS US 27 was decommissioned in and near Charlotte.

The entire highway is in Eaton County.

Lansing

Business Loop I-69, or BL I-69, is a business loop route in Lansing area. Beginning at I-96/I-69 at exit 93 west of the city, it runs easterly along Saginaw Hwy and Saginaw St concurrently with M-43. Within Lansing, BL I-69 utilizes a one-way pair of streets: Saginaw St eastbound and Oakland St westbound. Near its junction with US 127, M-43 departs to the southeast via Grand River Ave while BL I-69 turns northeasterly via Saginaw St until it terminates back at I-69 at Exit 94 in Clinton County northeast of E. Lansing.^[6]

The route was first designated in 1987 after the completion of the northern freeway loop of I-69 around Lansing. It is the longest business route in the state of Michigan at a length of over 14 miles (23 km). The portion of BL I-69 from BL I-96 in Lansing easterly was originally part of M-78.

The first mile of BL I-69 is freeway but upon intersecting 32nd St it turns into a one-way pair of surface street: eastbound along Oak St, westbound along Griswold St. In downtown Port Huron, BL I-69 turns northerly running concurrently with BL I-94 via Main St, Huron Ave and Pine Grove Ave. BL I-69 terminates at I-94/I-69 at the western end of the Blue Water Bridge.^[7]
