Michigan Highways: Historic US-25 |
 | | One of six mainline US Highways "decommissioned" in the state of Michigan, US-25 was originally designated as the US Highway to begin at Port Huron, head southwesterly through Detroit then southerly into Toledo, Ohio and then on through six other states to end on the Atlantic coast in Brunswick, Georgia. |
 | | Even though 152 miles of US-25's approximately 200 mile length were not concurrently designated with a parallel Interstate, the Department of State Highways in conjunction with their counterpart in the state of Ohio worked to truncate US-25 back to a terminus at the Ohio/Kentucky state line on the Ohio River at Cincinnati. |
 | | From the Ohio state line to north of Monroe, the Department of State Highways decided to revive the M-125 designation, playing off the "25" which had been in place there. |
