According to the BBC, the bongs are being disconnected for the clock and the surrounding tower to be restored.

Jaggs said the clock will be be "dismantled piece by piece with each cog examined and restored," The Washington Post reported.

According to CNN, the repairs will cost approximately $40 million.
