Due to an effort by St. Louisians and spearheaded by A.B. Greensfelder a new section of U.S. 66 stretching from the St. Louis city limits to the entrance of the Arboretum (now formally known as the Shaw Nature Reserve) at Gray Summit is dedicated as the Henry Shaw Gardenway. This effort was actually a work around solution to publically honor Henry Shaw due to his stipulation that the Garden would never bear his name in any official way. This however had no impact on the fact that St. Louis residents would continue as they had for decades to informally refer to the Garden as "Shaw's Garden."
