Nearly half of the trees on the grounds of the Gateway Arch will be removed and replaced with a different species.
The National Park Service said Thursday that more than 900 Rosehill ash trees will be taken out over concerns about the threat posed by the Emerald Ash Borer, a beetle that has killed millions of ash trees in 15 states. Officials at the Arch say the ash trees on the grounds are also showing signs of decline from urban factors like air pollution and less than ideal soil.
U.S. Secretary of Transportation Ray LaHood and Secretary of the Interior Ken Salazar await their turn to talk about the federal grant for the CityArchRiver intitiative at the Old Courthouse in St. Louis on Wendesday.
The renovation of the Gateway Arch grounds is being called a “magnificent project” by two presidential cabinet members.
Interior Secretary Ken Salazar and Transportation Secretary Ray LaHood were in St. Louis Wednesday to celebrate a new $20 million federal grant for the project. The grant will help pay for a new “pedestrian lid” over Interstate 70 so people can move more easily between the Arch and downtown St. Louis.
The agency planning the project, CityArchRiver 2015 Foundation, announced Monday that the grant will pay for roadway improvements along Interstate 70 near the site of the Arch, including a pedestrian land bridge over I-70 connecting the Old Courthouse, Luther Ely Smith Square and the Arch grounds.
