Business Routes of Interstate 96 - Farmington

Old BL I-96 was a former business loop of I-96, and is now a 4.74 miles (7.63 km) mile segment of unsigned state trunkline along Grand River Avenue through the city of Farmington, a northwestern suburb of Detroit in the US state of Michigan. The eastern terminus is at the M-5/Grand River Avenue junction southeast of Farmington and its western terminus is at the junction of M-5 and Grand River Avenue west of the city.

This highway was the original route of US 16 though downtown Farmington. In 1933, US 16 was routed onto a bypass route which had been constructed south of the city (the present-day Freedom Road) and the route through Farmington was retained as state trunkline. In 1957, a new bypass freeway was built just to the south of the old bypass as part of the "Brighton-Farmington Expressway" and the route through downtown was designated as "BUS US 16".

The original plans for I-96 called for it to replace US 16 and to run parallel to Grand River Avenue all the way from Farmington into downtown Detroit. Around 1959-1960, the Farmington bypass freeway was resigned as I-96 and in 1961, the business route was redesignated as "BL I-96". In 1977, as the Jeffries Freeway was completed, I-96 was rerouted along it south through Livonia and then east into Detroit, the portion of freeway bypassing Farmington was redesignated as M-102 (now part of M-5). Simultaneously, the BL I-96 designation through downtown Farmington was removed and Grand River Avenue became an unsigned state trunkline, a status it has retained to this day.
