Sowinski Sullivan served as the architect on a team tasked with providing design services for improving conditions at SEPTA’s 30^th Street Station, 31^st Street Entrance. The 30^th Street Station is one of the busiest stations in Philadelphia, Pennsylvania and the 31^st Street Entrance Improvement project was Phase 1 of the overall 30^th Street Station Improvements. The project goals were to improve ADA-compliant accessibility, enhance safety and security for both customers and employees, and improve operational efficiency and customer convenience.

The scope of work included replacing the existing SEPTA head houses located at the northwest corner of 30^th and Market Streets and at the southwest corner of 30^th and Market Streets with new structures which maintain the program of the existing head houses. At the northwest corner head house a pass through elevator was designed for pedestrian access from street level to concourse along with a stair that incorporated an integral bike channel allowing for improved transport of bicycles from street level to concourse level. In addition, SSA designed the station to be upscaled with point support glass, updated lighting, glass pavers to allow light to reflect throughout the concourse, re-designed fare line, an elevator for pedestrian access from concourse level to platform level, upgrading station finishes, and installing new ADA-compliant way-finding signage.
