Development, lack of maintenance, climate change and other factors have put historic American landmarks at risk, says the National Trust for Historic Preservation, which has compiled its 2019 list of the most threatened sites. It includes such famous places as the National Mall Tidal Basin in Washington, D.C., and Music Row in Nashville, as well as the Bismarck-Mandan Rail Bridge in North Dakota. The organization's annual compilation is a call to action. "As it has over the past three decades, we know that this year's list will inspire people to speak out for the cherished places in their own communities that define our nation's past," said a trust official, per CBS.
The campaign to save the Tidal Basin could cost as much as $500 million, the trust says. There is no plan yet to save the Industrial Trust Company Building in Providence, known as the Superman Building; Rhode Island's tallest building has been vacant and deteriorating for seven years. The threat facing Music Row is development, the trust says. More than 300 historic sites have appeared on the lists over the years, the trust says, and fewer than 5% of them have been lost. (Route 66 made last year's list.)
