 One plan, made in 1955 when the line was still owned by the City of Shaker Heights, involved extending it to the Sulgrave Road on the Shaker Heights/Beachwood border or even to Brainard Circle in Pepper Pike, but the city had little money at the time to implement such a proposal.Another plan proposed by RTA in 1978 called for a 1.5-mile extension of the Green Line east to Interstate 271 along with exit ramps from the interstate highway to a 1,500-car parking garage attached to a new station.The cost of the project was estimated at $29 million.
