To aid in navigation and addressing, segments of the loop have been given suffix letters by the local municipalities, which usually correspond to the local road name. For example, the portion of Highway 548 which is signed along D Line is named 548D, along Huron Line is it named 548H, etc.[3]

Highway 555
Secondary Highway 555, commonly referred to as Highway 555, is the former designation for a secondary highway in Blind River, which extended from Highway 17 to Granary Lake. The highway also had the street names Woodward Avenue in the main population centre of Blind River, and Granary Lake Road north of Highway 557.
When the route number was removed from the system in the 1990s, the portion of the route south of the Highway 557 intersection was renumbered as an extension of Highway 557. The Granary Lake Road section was entirely decommissioned from the provincial highway system, and now exists only as a local road.
In 1991, the Ministry of Transportation issued a report which proposed that the route be extended to meet Spine Road in Elliot Lake,[5] creating an alternate route which would reduce the length of a commute between Elliot Lake and Blind River by approximately 20 kilometres compared to the current routes of Highway 17 and Highway 108.[5] While the ministry has not announced a plan to proceed with the construction, in 2015 Elliot Lake's city council passed a motion calling for the project to be revived.[5]

Prior to the late 1990s, the Woodward Avenue segment of the highway was designated as Highway 555. The 557 designation applied only to Matinenda Road, while the 555 designation continued along Granary Lake Road. When Granary Lake Road was decommissioned from the provincial highway system, the 557 designation was extended along Woodward Avenue rather than the 555 designation being shifted from Granary to Matinenda.
The MTO does not maintain the 3.2 km (2.0 mi) section of Highway 557 south of the Granary Lake Road intersection through Blind River,[1] This section is signed as part of the highway for continuity to Highway 17.
