A 90-foot cellular telephone tower disguised to look like a flagpole will be erected near the Appalachian Trail east of Boonsboro.
The Washington County Planning Commission on Monday approved the site plan for the tower, submitted by AT&T Wireless.
One other commercial carrier may be located on the tower, according to information provided by the planning department.
The tower, called a "stealth" tower because of its disguised design, will be on the Old South Mountain Inn property at 6132 Old National Pike.
The Washington County Board of Zoning Appeals approved a special exception in April so the tower can be built.
While the height of the tower will exceed the height of surrounding trees by 10 feet, a flag will not fly on the tower and it will not be lighted, according to the Board of Zoning Appeals' ruling.
The ruling states there is a need for the tower in the South Mountain area because of a gap in coverage there.
