ARLINGTON, Va. (WUSA9) - Arlington National Cemetery officials say the Eternal Flame at the President John F. Kennedy gravesite is undergoing "significant upgrades" and the flame was moved to a temporary burner off to the side for only the second time in history. The first time a temporary flame was used was Nov. 25, 1963 when President Kennedy was laid to rest, according to officials.
Officials say the markers for President Kennedy and his family can still be seen during the work and that no changes are being made to the gravesites.
According to officials, the upgrades will make the flame system more energy efficient and easier to maintain. The upgrades include new gas lines, automated controls, new electrical conduit and cable, an energy-efficient system, relocating gas pressure regulators to outside the vault to make things easier to maintain, and making new burner assemblies that are "naturally aspirated to reduce maintenance and utility costs."
Officials expect the process to last three weeks.
