Gateway Arch goes dark through September to protect migrating birds

An iconic American landmark that has been a part of history for more than half a century will be going dark this month in a bid to save lives. The Gateway Arch, which has triumphantly bent over St Louis, Missouri, will now bow to nature. Throughout the month of September, the lights on this Midwestern marvel will be turned off as millions of migratory birds begin their journey south, reported the NY Post.Every evening, the arch's exterior lights will be turned off to reduce the risk of disorienting the birds, as the brightness can cause them to veer into buildings or stray from the correct migration route. St Louis and its resplendent Arch sit critically on one of North America's busiest Avian superhighways, the Mississippi Flyway.
