The hundreds of ash trees that populate the grounds of the Gateway Arch will be coming down starting Friday.  The Emerald Ash Borer is a threat to the 800 trees.  The National Parks Service says the age of the trees and poor soil quality are also factors.  The trees will be replaced with a variety of different species, including a large number of London Planes -  a variety that is popular in many metropolitan areas like New York, San Francisco and Paris. 


You can keep an eye on the day-to-day progress of the renovations being done on the Arch grounds.  The CityArchRiver 2015 Foundation launched a webcam in March.  An up-to-date view of the construction as well as past images and time-lapse videos can be checked out at the link:
