Source-derived summary

State Route 270 (SR 270) is a state highway in

Whitman County, Washington, United States. It connects the city of Pullman to U.S. Route 195 (US 195) at its west end and Idaho State Highway 8 near Moscow, Idaho, at its east end. The 10-mile-long (16 km) highway is one of the main roads in Pullman and connects the campuses of Washington State University and the University of Idaho.

Route description

SR 270 begins at an un-signalized Y intersection with US 195 in the hills west of Pullman. The two-lane highway travels east through a cut in the hills on Davis Way and passes several residential subdivisions on the outskirts of the city. After descending from a hill and following the South Fork Palouse River and a freight railroad into downtown Pullman, SR 270 turns southeast and begins a short concurrency with its parent route, SR 27, on Grand Avenue. The two highways travel south on Grand Avenue for a two blocks before SR 270 turns east onto a pair of one-way streets: Southeast Paradise Street for eastbound traffic and East Main Street for westbound traffic.

The two streets carrying SR 270 reunite after three blocks and the highway continues east on the four-lane Main Street towards the Washington State University campus. The highway turns southeast and bypasses the campus, crossing over the river and railroad and passing several student dormitories. After intersecting Bishop Boulevard, SR 270 turns due east onto the Pullman–Moscow Highway, which follows Paradise Creek along the south side of the university campus.

Editorial summary

This brief starts where responsible research should: with the source description of “Washington State Route 270” as highway in Washington. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 256-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1964. The account is most persuasive where Washington, State and Route can be independently traced.
Editorial analysis

Why this record matters

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

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Feb 1, 2026. The linked authority identifier is Q836138. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
