The various connectors that span the Schuylkill each have vary-
ing levels o inrastructural knot-tying. Each East-West connec-
tor undergoes a airly unique interaction with North-South
dividers. Within the Schuylkill boundary are elevated rail lines,
ground exposed rail lines, rail lines that traverse below spaces,small streets, the I-76 on and o ramps, and the major bridges:

A major intersection, this could be a place to add a much more pedestria
bridge, as well as a vertical connection to the western side o the Schuylk
Adjacent to the uture Penn Park, this undeveloped strip along Walnut street could be made to
transition pedestrians rom the top level down to the park. Guiding pedestrians down at this
site could enable the development o activity here, placing ocus on transitioning and reocus-
ing rom the top level to the sunken level.

This is the rst point along Walnut street rom University City where the inrastructural
boundaries and datum shit begin. Three public vertical connectors are within the
vicinity, but take pedestrians to horizontaly severed places.

One block south o Walnut street, a transition o commercial and oce spaces to residential
occurs. This is an oportune moment to bring pedestrians onto the schuylkill-linking network
o new buildings and to the river. A block within the path o the orientation o this street may
provide a signal to bring pedestrians over the rail boundary. Programs o commercial and
public-use types (such as libraries or gyms) could provide a healthy level o magentism

the development o blocks and a point to attract pedestrians.
