The Bridge With a Zipper

The Golden Gate Bridge. It is a media, transportation, and political icon. The bridge has a major safety issue which has only just recently been fixed. The problem?  The bridge has been without a barrier since 1962. But an invention that you are most likely wearing right now has just been added to fix safety and speed among the travelers on the San Francisco Golden Gate bridge. This is part one of three short articles titled “Big Builds”.

GGB (Golden Gate Bridge) has 10 lanes. Previously, lanes would change direction throughout the day. Now, vehicles known as bridge zippers move chain link barriers across two lanes throughout the day to improve speeds and stop head on collisions. Imagine, well, a zipper.

This 30 million dollar improvement can help residents of San Francisco and surrounding areas stay safe during the daily afternoon and morning commutes.
