Source-derived summary

The Interstate Highways in Montana are the segments of the Dwight D. Eisenhower National System of Interstate and Defense Highways owned and maintained by the Montana Department of Transportation (MDT) in the U.S. state of Montana.

The state's Interstate highways, totaling 1,198 miles (1,928 km), were built between 1956 and 1988 at a cost of $1.22 billion. 95 percent of the system serves rural areas, the highest proportion of any state under Interstate program. The entire Interstate system in Montana was designated as the Purple Heart Trail in 2003.

Editorial summary

This brief starts where responsible research should: with the source description of “List of Interstate Highways in Montana” as wikimedia list article. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1956, 1988, 2003—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where List, Interstate and Highways can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as wikimedia list article. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q29915127. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1956, 1988 and 2003.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
