In 1931, the old Calvary station was replaced by South Boulevard and it was opened on July 1, 1931. Designed by Arthur U. Gerber, South Boulevard consists of a winding central platform to the shape of the street that overlooks. It is now very similar to the original station, only catenary maintained by steel arches disappeared in 1973 during the installation of an electric rail to the ground while the lighting was renewed in 1998. For the rest, except for renovation from 2004 to 2005, the structure has not changed.
The current station has been in place since July 1, 1931, when it replaced the Calvary Cemetery stop to the south, to better serve the developing residential area directly to the north of the cemetery. The station has only received little renovation since then, like new lighting and signage.
The closure of the South Boulevard station (along with Foster) appeared as part of three of the CTA's six potential options for the renovation of the Purple Line and northern section of the Red Line.
