 With the elimination of PCC cars and complete conversion to new LRV cars shortly thereafter, the loop at the end of the Green Line was no longer needed, but it remains and is the only loop in the light rail system.When Richmond Road was widened in 1988 and the bridge over the extended right-of-way at Richmond Road needed replacement, it was determined not to replace it, but instead to fill in the right-of-way for the widened Richmond Road.When express lanes were added to Interstate 271 in 1994, it was decided to replace the extended bridge over the Shaker Boulevard right-of-way with shorter bridges over only the roadway portions.
