In 2016, the Metropolitan Government of Nashville & Davidson County (Metro) turned their sights to Madison Station Boulevard (once known as the Neely’s Bend Extension project). As a component of Metro’s planning of the region, councilmember Nancy Van Reece spearheaded an effort to bring this long-awaited project to reality. In response to the Mayor’s Amended Executive Order 031, committing to the Green and Complete Streets Program, the project’s primary goal was to promote multimodal options such as pedestrian walkability, enhanced bike paths with circulation, and accommodations for automobiles with a sustainable and environmentally-responsible footprint — all vital components for the reimagining of Madison Station Boulevard. With a focus to rebuild the community, it began to take shape with Metro selecting the team to bring the transformative project to life. TTL led the design of the landmark project. Madison Station proved to be especially complex due to the many challenges that included balancing transportation needs, drainage issues, and existing infrastructure.
