I have a suggestion for the Rail Trail Vision. This is a really nice green space with a great view of the Charlotte skyline. However no one can get to the space because it is inside a looping exit from the interstate. How about building a pedestrian overpass to the green space (smile).
Actually the rail trail vision has plans for a three mile park connecting green spaces along the light rail tracks in the Southend.
This photo was taken at the intersection of South College Street and Morehead Street.

That would help.
