 A tunnel previously connected the two stations, but was closed in the 1980s for unknown reasons.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, which owns 3000-3020 Market Street directly above the subway station and is planning the Schuylkill Yards megaproject.
