The South State Street Corridor Transportation Study is a study of the conditions of South State Street from Ellsworth Road to Oakbrook Drive. It is a complement to the recently completed South St​​​ate Street Corridor Plan (PDF) and the City's Transport​ation Master Plan Update. The project will evaluate the corridor from a multi-modal, Complete Streets perspective. The study will look at safety, mu​lti-modal considerations, as well as alignment with the recent land use vis​ion completed for the corridor. The eight study goals are:

  • Safety: provide safe conditions for all travelers

  • Entry: create a more attractive entry to the city

  • Pedestrians: improve conditions for pedestrians along/across State Street

  • Bicycles: provide a safe place for bicyclists separate from travel lanes

  • Transit: enhance transit conditions through traffic flow and stop accessibility

  • Vehicles: maintain reasonable traffic operations along the corridor

  • Land use: support planned land use described in the South State Street Corridor Plan

  • Access: ease accessibility of corridor businesses

Why is this study being done?

South State Street is a heavily utilized multi-modal corridor connecting the City of Ann Arbor to Pittsfield Township to the south. The corridor also provides the region with a connection to points east and west via an interchange at I-94. Currently, the area suffers from inconsistencies in sidewalk widths and existing configuration of medians, traffic lanes, and access points.

How long will the project take?

The study began in September 2014 and is expected to be completed in April 2016. Project steps are outlined in the South State Street Transportation Plan Schedule (PDF).

What are the next steps in the project?

  • Use analysis and public feedback to select a recommended alternative, from the three alternatives being considered:
    • Alternative 1 – narrow median with direct left turns
    • Alternative 2 – narrow median with roundabout intersections
    • Alternative 3 – wide median with indirect ("Michigan") left turns
  • Conduct further preliminary design
  • Present recommended alternative at subsequent public workshops in early 2016

Who is involved in making decisions?

In addition to public input, representatives from the consulting team, the City of Ann Arbor, Pittsfield Township, Ann Arbor Area Transportation Authority (AAATA), Washtenaw Area Transportation Study (WATS), and the Michigan Department of Transportation (MDOT) are all assisting in the project.
