The lid is on. Construction crews have completed one phase of the $380-million overhaul of the Gateway Arch grounds in downtown St. Louis. Workers wrapped up work Thursday on the land bridge over Interstate 44 downtown that will connect the main grounds to the Old Courthouse and the rest of the city.
Next will be the work on the storm drain system, then landscapers will come in to set up the pathways, trees and other green space. The water runoff will be collected and used for irrigation on the grounds. The parking garage on the northern end of the Arch grounds will be torn down in January to be replaced by a grass amphitheater and garden providing easier access to Laclede’s Landing. Leonor K. Sullivan Boulevard along the riverfront is being raised out of the floodplain, and Ash trees are being replaced throughout the grounds with new trees.
