I-95 Section CAP
(Central Access Philadelphia)

The I-95 Central Access Philadelphia (I-95 CAP) project is a vision of the 2011 Master Plan for the Central Delaware River Waterfront. It is a multifaceted plan that calls for multimodal improvements along the Delaware River waterfront to promote long-term economic development. A key feature of this plan is to improve access and views to the waterfront from Center City and to create a new vibrant landscaped public space for the region and its visitors.

A traffic model comprised of 92 intersections was developed for assessment of future traffic conditions and temporary traffic conditions associated with staged construction and detours. A comprehensive traffic management plan (TMP) is being prepared to minimize impacts resulting from full closures of I-95 (nighttime work only), South Street, Walnut Street, and Chestnut Street through the study area.

Roosevelt Plaza Pop-Up

Roosevelt Plaza Park (RPP) is a historic 75,000-sq.ft. park in front of Camden’s City Hall reopened in June 2012. A collaborative effort between Pennoni, Sikora Wells Appel and New American Public Art created two pop-up iterations to enliven the existing park.

Each version of the pop-up focused on providing a safe, welcoming public space for residents and city workers, providing areas for eating, relaxation and public art. Intermediate Bulk Containers were used to create a seating area and a large light installation with a shade structure. The second reincarnation, RPP water was more interactive and included various ways to learn about the city’s stormwater management efforts, including a rain curtain, water organ, and on-site irrigation system. The project received the APA-NJ Chapter’s Outstanding Implemented Plan Award and the Great Places Award from the EDRA and Project for Public Spaces.
