ST. LOUIS (KSDK) - The Missouri Botanical Garden is beginning work to save a historic stone wall that is more than 150-years-old.
Portions of the perimeter wall were completed in 1856 with Henry Shaw's original design. A grant from the Department of Interior, National Park Service through the Save America's Treasures grant program will allow for preservation and rehabilitation of a section of the east perimeter of the wall.
The crumbling section runs along Tower Grove Avenue from the Garden's Museum Building to just north of the Shoenberg Administration Building.
Age, weather, traffic vibration, sidewalk relocation, and tree roots have all contributed to the deterioration.
A spokesperson for the Garden says workers will remove and restore limestone pieces and build a new foundation with permeable mortar, which will allow water to run through the wall.
Eight pin oak trees will also be removed after roots caused damaged to both the sidewalk and the wall.
Construction is expected to last approximately six months, during which one lane of Tower Grove Avenue will be closed to traffic, marked with concrete barricades.
Landscaping will complete the project, which will include shrubs and small canopy trees.
