Investment in the City’s Infrastructure

Listed on the National Registry of Historic Places, the South Street Bridge is a visible gateway which spans the Schuylkill River. The new bridge and viaducts design reflects the increased importance of walking, bicycling, balanced traffic planning, and contextual civic infrastructure in the City of Philadelphia.

Synterra Ltd / H2L2 completed the design for the new South Street Bridge in Philadelphia. The quarter mile bridge and viaduct is one of the main vehicular and pedestrian connectors over the Schuylkill River between University City and Center City Philadelphia. It is also a symbolic entry point as you approach the city from the south along the expressway. The bridge consists of 4 car lanes, 2 bike lanes, and “city-street” scaled sidewalks with pavers and lampposts. The centerpiece of the bridge is four lantern-like towers that symbolically define the bridge as a gateway to and from the city. Synterra Ltd / H2L2 worked closely with the City, Community Groups, and Gannett Fleming Engineers to develop the design, which was based on four main principles:
1. that the bridge be an important civic gesture;
2. that it have outlook areas incorporated into the tower elements for viewing the city, which is something that was popular with the original bridge;
3. that the towers have continuity below and above the road deck so the bridge can be experienced holistically;
4. that the bridge be pedestrian friendly and feel very safe, especially in the outlook areas. With these points in mind, Synterra Ltd / H2L2 has developed a stunning new addition to Philadelphia’s exciting river landscape.
