Business Routes of Interstate 75 in Michigan - Grayling

Grayling

Interstate 75 Business Loop, or BL I-75 is a loop route running through Grayling, Michigan, USA. It follows a former routing of US 27 through town.

BL I-75 is concurrently designated with M-72 between S. Down River Rd. and Kalkaska Rd. At Kalkaska Rd., M-72 turns west with M-93 out of downtown. BL I-75 then runs north with M-93 concurrently to the northern terminus of BL I-75 at exit 259 on I-75. Direct access between I-75 and M-72 is limited. Ramps only connect I-75 northbound to BL I-75 northbound and BL I-75 southbound to I-75 southbound. Traffic connecting between I-75 and M-72 must use BL I-75, no interchange is provided at the M-72 overpass.

With the opening of I-75 in the Grayling area on December 4, 1961, the former routing of US 27 from the "US 27 Split" south of Grayling north to the Crawford/Otsego county line is decommissioned. US 27 from the split north to Grayling is obliterated by the new freeway. Sections left untouched became a new BL I-75 running north to M-72/Huron St. From there BL I-75 was routed along M-72 to M-93 and M-93/Hartwick Pines Rd. back to I-75.
