Taxiway Shoulder Markings
Taxiway shoulder markings mark stabilized shoulder areas which are not full strength or
where aircraft taxiing is undesirable. The markings consist of nonretroflective yellow
bars painted on the shoulder surface perpendicular to the taxiway edge. The length of
the bars are 25 feet long or to within 5 feet of the outer edge of the shoulder paving
whichever is less and 3 feet wide. Along straight taxiway segments, the bars are spaced
equally not more than 100 feet apart with a bar at the PT of a curve or the end of the
taxiway or shoulder paving. On curves, bars are spaced along the taxiway edge not
more than 50 feet apart (see Figure 4-10).
