State Route 266 extended from
SR 12 (now
US 340 Business) in
Stanley east, north, and west along current
SR 689 via
Ida and
Fairview to
Luray. After an
overlap with
US 211 (now
US 211 Business), SR 266 turned north on Lee Street, then ran northwest along current
SR 675 in the direction of
Edinburg, extending beyond the
South Fork Shenandoah River to the northern intersection with SR 615 at the foot of
Massanutten Mountain. north of Luray were added to the state highway system in 1928 as
State Route 821, which was extended another in 1931. South of Luray, two segments of each were added at either end in 1930, both as
State Route 836. ( at the south end had previously been part of
SR 16 from 1918 to 1922, and even earlier was part of the
Blue Ridge Turnpike.) The gap between Stanley and Luray was filled in 1932. SR 821 and SR 836 became SR 266 in the
1933 renumbering, except for the southernmost , which was instead part of
SR 231, disconnected from the main part of that route by a never-improved piece of the old Blue Ridge Turnpike over
Fishers Gap.). At the same time, a stub of SR 231 east of Fishers Gap was downgraded, leading to the extension of SR 266 to Stanley, replacing the disconnected piece of SR 231 west of Fishers Gap. This remaining piece of SR 266 only lasted until 1952, when it too was downgraded as a new SR 689. ;Major intersections ==SR 267==
