There are no earthquake-safe bridges or buildings. They can be re-inforced to be earthquake resistant but when the 'big one' hits, they're all coming down. I'm talking about the 9.5 subduction zone quake that is due on the US west coast at any time.

The support beam should not be tied with the roof. The natural frequency of the bridge should not match with the earthquake frequency. No matter how far the support beam is located.

A doorway is not the safest place during an earthquake!!!! In modern day homes a doorframe is no stronger than any other part of the house. The number one risk during an earthquake is falling or flying objects. A door provides no cover and the door it self can injure you when it flaps back and forth. The best advice is to go under a table or desk and hold on to protect you from flying objects. Most building do not collapse during earthquakes. DO NOT run to the exterior of the building as that area is usually the weakest. If you are inside stay inside if you are outside stay outside.
