The station opened on November 6, 1955, by the
Philadelphia Transportation Company (PTC), built as a replacement for the elevated
32nd Street station that had opened in 1907 as part of the
Philadelphia Rapid Transit Company's original
Market Street subway–elevated line from to , which was elevated west of 23rd Street. The PRT announced a project to bury the elevated tracks between 23rd to 46th streets in the 1920s. The PRT went bankrupt in 1939 and was reorganized as the PTC, which began building the rest of the tunnel in 1947. In December 2018, SEPTA received a $15 million grant from the
United States Department of Transportation to make significant improvements to the station. The improvement project was projected to cost over $37 million, with remaining funds contributed by SEPTA's capital budget and the developer
Brandywine Realty Trust, and is planning the
Schuylkill Yards megaproject. The project calls for improvements to the station's mezzanine, as well as reopening and renovating the underground concourse connecting the subway station with the main 30th Street Station building. The full project was expected to be completed in 2021, but was not ultimately completed until April 2024. The
30th Street Station District, a development plan, called for the station house at the northwest corner of 30th and Market streets to be rebuilt. Work began on station renovations in 2020. New signage with the name, the first to adhere to
SEPTA Metro, was added in February 2024. The name change officially took effect when the renovated station opened in April 2024. == Station layout ==
