The Gateway Arch will not be illuminated at night from October 16, through November 17, 2023, as the National Park Service (NPS) installs a new, state-of-the-art lighting system reducing the overall energy needed to light the Arch by 60%.

The new fixtures replace the 26 static Xeon skylights installed one week after the reopening of the Arch in 2018. LED and IP65 rated, the new fixtures are far more efficient requiring only 1200 watts per unit versus the 7000 watts required by the current lighting system.

In addition to being more energy efficient, the new lights are equipped with cutting-edge technology. The updated Arch lighting system is more accurate in controlling focus and color temperature, making the Arch appear brighter while reducing stray lighting for migratory birds and flares in the night sky.

The upgrade is being paid for by the Gateway Foundation. The Foundation paid for the installation of the current lights and continues to maintain the system per the original installation agreement.
