Oregon Route 501
Ssate highway in Benton County, Oregon, Unted States
Oregon Route 501 (OR 501) is an Oregon state highway running from the town of Alsea south 9.49 miles where it ends and turns into Lobster Valley Road at the intersection of Hazel Glen Road near the Benton-Lane County line. OR 501 is known as the Alsea-Deadwood Highway No. 201 (see Oregon highways and routes). It is 9.49 miles (15.27 km) long and runs north–south, entirely within Benton County.

Route description
OR 501 begins at the intersection of OR 34 in the small rural town of Alsea, from there, it heads south through mostly forested, rural land, following the route of the original logging roads making it extremely curvy at its southern end where it ends and turns into county maintained Lobster Valley Road.
History
OR 501 (The Alsea-Deadwood Highway) was originally planned to start in the small logging town of Alsea, travel south through Lobster Valley, continuing to the small logging community of Paris and south to end at OR 36 in Deadwood. The Highway was never completed south to Paris from Lobster Valley and it was later decided by the Oregon Highway Commission to abandoned any future plans to complete the Highway as originally planned.
The original route of OR 501 was to connect OR 34 in Alsea to OR 36 in Deadwood, hence the name "Alsea-Deadwood Highway".

Why this record matters
The phrase “ssate highway in Benton County, Oregon, Unted States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated May 9, 2025. The linked authority identifier is Q2494181. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2002 and 2009.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.
