Padlocks with couples' names are set to be removed from the Pont des Arts bridge in Paris starting Monday.  

For years, tourists in Paris have been placing padlocks on the famous bridge and throwing the keys into the Seine, a symbol of love that cannot be broken.

However, the locks have become dangerous for the bridge, after a part of the bridge's fencing fell off and into the Seine under the weight of the locks, according to NPR.

The practice of placing padlocks on the Pont des Arts creates problems such as "sustainable degradation of public heritage monuments and a risk to the safety of visitors, Parisians and tourists alike," Mayor Anne Hidalgo said in a statement Friday. Hidalgo launched a PR campaign last year to stop the practice, encouraging couples to take a selfie to commemorate their love instead.

City officials made the decision to close the bridge for a week starting June 1 to remove the estimated one million locks, weighing around 45 tons. The locks will be replaced by an installation from international artists this summer before transparent Plexiglass panels will be installed in the fall, according to Forbes.
