Witherspoon St. Improvement Project-Nassau to Green

Project Overview

The Princeton Engineering and Planning Departments are jointly launching a master planning process to improve Witherspoon Street, from Nassau Street to Valley Road. The improvements will include, but not be limited to the following:

  • Crosswalk replacements
  • Curb and sidewalk replacement on the southern end of Witherspoon Street; this will extend from building frontage to the building frontage
  • Other utility company improvements
  • Placemaking and streetscape improvements such as benches, bike racks, bike corrals, newspaper receptacles, and trash receptacles
  • Road repaving
  • Storm and sanitary sewer improvements, as needed
  • Street tree removals and replacements
  • Traffic signal improvements at Paul Robeson Place / Wiggins Street / Witherspoon Street
  • Updated street lighting

The first phase of this project was to gather data on the street regarding the roadway features as well as the private basement areas that are accessed via the public sidewalks to create a map of Witherspoon Street.


  • In February 2020, the Engineering and Planning Department conducted a public meeting regarding the conceptual layout of Witherspoon Street between Nassau Street and Valley Road.
  • In September 2020, the Engineering and Planning Department conducted a second public meeting regarding the conceptual layout of Witherspoon Street between Nassau Street and Green Street.
  • It is anticipated that a third public meeting will occur in December 2020 after the receipt of a traffic study for potential  modifications to Witherspoon Street between Nassau Street and Green Street.
  • Construction of sanitary sewer improvements between Nassau Street and Green Street is anticipated to occur in early 2021.  Construction of roadway improvements is anticipated to occur in mid to late 2021.
