FENG SHUI AND BRIDGES

In Feng Shui, it is believed that a bridge would have an effect on ones home depending on its placement.

• Energy around bridges is very powerful due to heavy concentration of traffic... and houses built at either end of a bridges will usually suffer from too much yang energy causing an unsettled atmosphere, and conflict between residents of such household.
• A bridge that passes directly over your home is not good. 
• A bridge that directly points at your property could bring forth obstacles and difficulties in your life. 
• A bridge that runs parallel to your house is okay. 
• Bridges linking ponds and other natural elements are usually auspicious.
