Business US Highway 10 (
Bus. US 10) was an approximately
business loop running in
Pontiac. It was redesignated in 1986 as a business route of
US 24 after
US 10 was truncated to
Bay City. The roadways it used were at four lanes where they carried two-way traffic, and two or three lanes where they carried
one-way traffic through the area. Bus. US 10 started northwest of downtown at the intersection of Telegraph Road and Dixie Highway in
Waterford Township before crossing into the city of Pontiac. From there, the highway followed Dixie Highway southeasterly bordered by residential neighborhoods to the north and rail yards to the south of the four-lane street. From the intersection with Montcalm Street southward, the eastbound direction branched off to follow Cass Avenue two blocks to the south of Oakland Avenue. At the northern end of downtown, Bus. US 10 merged onto a loop formed by Wide Track Drive around the downtown core southward to Saginaw Street. The loop is shaped like an upside-down tear drop that is about four blocks wide at the northern end tapering to a single intersection at the south. Wide Track Drive also carried the two directions of
Business Loop Interstate 75 (BL I-75) around downtown Pontiac between Saginaw Street and Perry Street. The two directions of BL I-75/Bus. US 10 intersected
M-59 on opposite sides of the central business district at Huron Street. The business loop continued southward along Wide Track Drive to the intersection of Saginaw Street. From there, BL I-75/Bus. US 10 followed Saginaw south toward South Boulevard, which marked the southern end of Saginaw and the northern end of
Woodward Avenue, and from there past the hospital and out of the city of Pontiac. South of the city limits, the roadway was bordered by residential subdivisions. At Square Lake Road, Bus. US 10 turned westward, BL I-75 turned eastward and
M-1 continued south on Woodward Avenue. Bus. US 10 followed Square Lake Road for about before terminating at an intersection with US 10 (Telegraph Road). In 1919 when the state highway system was first numbered, Nine years later, US 10 was moved off Woodward Avenue between Pontiac and Detroit to follow the
Lodge Freeway and Telegraph Road. Bus. US 10 was extended westward along Square Lake Road from the intersection of Woodward Avenue to the junction with Telegraph Road so that it would continue to connect with its parent highway on the southern end. In 1985,
MDOT received permission from the
American Association of State Highway and Transportation Officials to truncate US 10 to Bay City, 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.
