 When Shaker Boulevard east of Warrensville Center Road was laid out by the Van Sweringen brothers in the 1920s, it included a broad median strip with room for four rapid transit tracks as well as a high-speed automobile parkway.The rapid transit right-of-way extended along Shaker Boulevard to Brainard Road and from there along Gates Mills Boulevard all the way to near Mayfield Road, where it ended in a large loop suitable for use as a streetcar yard.The Shaker Boulevard line of the Shaker Heights Rapid Transit was expanded one mile east from Warrensville Center Road to Green Road in 1936.
