Columbia, TN – The City of Columbia is pleased to announce the successful completion of the Columbia Infrastructure and Greenspace Improvement Project in downtown Columbia. This project, made possible through a partnership with Columbia Main Street, was funded by General Motors through the GM on Main Street Grant.
