Closed, Hazardous, and Other Area Markings
Where an operational requirement exists, there are provisions for marking closed,
hazardous, and other airport areas.
Closed Area
A closed area may be a runway, taxiway, or any other movement area (for example,
parking apron) that was once used but is no longer considered usable. It may be a
temporary condition, such as during construction, or permanently closed.
Closed Runway Markings
Closed runways are marked with crosses at each end near the entrances to intersecting
active runways and taxiways and at intervals not greater than 1,000 feet. The crosses
are painted with nonretroreflective yellow paint. The arms of the crosses intersect at
right angles and are 10 feet wide and 60 feet in overall length (see Figure 4-6).
Figure 4-6 -- Closed runway markings.
The distance of a closed marking cross from the ends of a closed runway or from edges
of intersecting active runways or taxiways shall not exceed 10 feet. Permanently closed
taxiways have all taxiway markings removed or obliterated and yellow crosses painted
on the surface. Temporarily closed taxiways may either have the crosses painted yellow
on the surface or formed by tape or plywood secured in place
Closed Taxiway Markings
Closed taxiways are marked with crosses at each end and at potential entrances and
intersections with active runways or taxiways. Crosses also appear at intervals not
greater than 1,000 feet apart along the closed length. These crosses are painted with
nonretroreflective yellow paint. The arms of the crosses intersect at right angles and are
not less than 5 feet wide and 30 feet in overall length (see Figure 4-7). The distance of a
closed marking cross from the ends of a closed runway or from edges of intersecting
runways or taxiways shall not exceed 10 feet. Permanently closed taxiways have all
