 RTA took over operation of the Shaker Rapid Transit from the City of Shaker Heights on September 5, 1975, and in 1978 it adopted the designation Green Line for the Shaker Boulevard line, the color green being selected because the line terminated at Green Road.There have been various proposals to extend the line east from Green Road.Until 1988, bridges were already in place over the right-of-way at Richmond Road and Interstate 271, and poles had been erected along much of the right-of-way decades earlier.
