Why this record matters
“Maryland Route 104” is worth following because a concise public description often conceals a longer documentary argument. Here, Maryland, Route and State provides the most credible route into that argument.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Jan 17, 2026.

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.
