New Smart Bridge

Since there was already a video showing the collapse of the Tacoma Bridge and why it happened, I decided to try and find new advances in bridge building technology.  I found that civil engineers are now creating what they call a “smart bridge”.  After the collapse of the Minnesota bridge into the Mississippi River, engineers decided new precautions needed to be taken.  Although the Minnesota bridge did not collapse due the resonance, some of the technology now implemented in the new Minnesota smart bridge could have helped detect the resonance of the Tacoma Narrows bridge before the collapse.  Engineers are now placing sensors in the concrete of bridge to detect movement of the concrete, vibrations through the bridge, and even corrosion of the bridge.
