Which statement describes precedence between power lines ROW and HWY 197/A?

• A. HWY 197/A ROW
• B. A local road ROW
• C. The power lines ROW
• D. The power lines ROW over HWY 197/A

Answer: (D)

When two right-of-way corridors share the same airspace, the controlling reference is the higher-priority obstacle, which in this case is the power lines. Power lines represent a fixed, high-risk obstacle with a defined clearance, so their ROW governs over a roadway ROW. Therefore, the power lines ROW takes precedence over HWY 197/A, and the power lines define the controlling reference for planning and avoidance.
