Nashville Public Library, Edgehill Branch
Free lot, open during library hours
Metro publishes this one itself. Nashville Public Library lists Edgehill among the branches that "offer free parking in a public lot during operating hours," and the branch's own page carries Free Parking in its amenities. Hours as of 8/13/26: Monday through Friday 10am to 6pm, Saturday 10am to 5pm, closed Sunday. The permission is bounded by those hours and Metro says nothing about parking there outside them. Note the address: this is the Edgehill end of 12th Ave S, north of Wedgewood, not the 12 South strip. There is a drive-thru book return, so the lot is a real one.
