Yes, photographing bridges, dams, and major infrastructure in Pakistan is often restricted. These are considered sensitive for security reasons.
Types of restricted sites
Bridges, dams, power plants, and other key infrastructure are classified as sensitive and are not open for unrestricted photography.
What may happen
Security personnel may intervene, ask questions, or request deletion of images if such sites are photographed.
Public visibility
Even if these structures are visible from roads or public spaces, photography may still be restricted.
Common misunderstanding
Seeing infrastructure in public does not mean it can be freely photographed. Many such sites are protected.
