Source-derived summary

M-154 is a state trunkline highway in the U.S. state of Michigan. It is entirely on Harsens Island at the mouth of the St. Clair River. It is one of only three trunklines in Michigan on islands. The other two are M-134 on Drummond Island and M-185 on Mackinac Island. Access to Harsens Island and M-154 is provided by ferry which runs year round. The highway was first designated in 1931, and realigned on the island within the next two years.

Route description

M-154 begins where Green Road merges with South Channel Drive on Harsens Island at the mouth of the St. Clair River. From there the road travels northward around the east edge of the island for about 2.5 miles (4.0 km) before it cuts a block inland.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as highway in Michigan, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 23, 2025. The linked authority identifier is Q2354862. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1931.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
