Welcome

This is the Engage Ann Arbor site for the Ann Arbor Roadway Rightsizing (A2R2) Project.

Background

The goal of this study is to improve safety, reduce vehicle speeds, and enhance multimodal connectivity along arterial streets. This project will result in conceptual designs for the ten corridors that are responsive to the Moving Together Towards Vision Zero Transportation Plan and A2ZERO plan.


The ten A2R2 Corridors include:

  1. Stadium (Washtenaw split to just west of Seventh)
  2. Stadium/Maple (just southeast of Pauline to Dexter)
  3. E. Packard (Eisenhower split to US 23)
  4. Eisenhower (Ann Arbor-Saline to Packard split)
  5. S. Main/Ann Arbor-Saline (Stadium to I-94)
  6. S. State (just north of Oakbrook to Ellsworth)
  7. Plymouth/Broadway (US-23 to Division)
  8. Huron Parkway (Platt split to Nixon)
  9. Green (Plymouth to Burbank)
  10. Fuller/Glen (Catherine to Glazier Way)

Why is this project being done?

In 2021, the City of Ann Arbor adopted the Moving Together Towards Vision Zero Comprehensive Transportation Plan, which is organized around achieving two big goals:

  • Vision Zero – No one dies or is seriously injured on Ann Arbor’s streets
  • Carbon Neutrality – through reduced car dependence and electrification

In pursuit of these goals, the City recognizes that:

  • Vehicle speed is a major factor for how likely and how severe a traffic crash will be,
  • People walking and cycling make up an outsize proportion of severe crashes, and
  • People need to feel confident and capable to move outside of a large vehicle

The Moving Together Towards Vision Zero Transportation Plan recognizes that a disproportionate number severe crashes occur on higher speed, wide arterial streets and intersections. As a step to direct attention and resources to the high crash severity streets, the City published a Speed Management Program and Toolbox, identifying a set of tools for street designs that produce lowered vehicle speeds and increased driver attention.

The A2R2 aims to improve safety, reduce speeds, and enhance multimodal connectivity along arterial streets. This project purpose is aligned with the broader Moving Together Towards Vision Zero goals through strategies such as redesigned intersections, quick-build treatments, and community engagement.

Work to be done

The Ann Arbor Roadway Rightsizing (A2R2) project will evaluate the feasibility of “rightsizing” arterial streets. Rightsizing refers to re-purposing excess motor vehicle traffic lanes for other uses such as dedicated transit lanes, separated bike lanes, or additional sidewalk and amenity space.

Roadway Rightsizing projects can reduce speeds, better organize traffic, address systemic safety issues, and incorporate planned transit and bicycle infrastructure throughout the City.

This project will result in conceptual designs for the ten corridors that are responsive to the Moving Together Towards Vision Zero and A2ZERO plan.


Funding Source

Council-directed use of the city's major streets Act 51 resources.


This project will result in conceptual designs for ten corridors that will apply proven safety countermeasures to improve safety, reduce vehicle speeds, and enhance multimodal connectivity along arterial streets.


Ann Arbor Road Resizing (A2R2) project extent.

The City of Ann Arbor has a long history of Roadway Rightsizing projects including these examples from the last decade:

  • Pauline Blvd from S Seventh St to S Main St (2025)
  • S Fifth St from E William St to E Madison St (2025)
  • Platt Rd from Huron Pkwy to Packard St (2024)
  • Earhart Rd from Glacier Hills Dr to Greenhills Rd (2023)
  • S Main St from William St to Stadium Blvd (2022)
  • Packard Rd from E Eisenhower Pkwy to US-23 (2022)
  • Miller Ave/Catherine St from N First St to N Division St (2021)
  • S Industrial Hwy from Stimson St to E Eisenhower Pkwy (2021)
  • Division St from E William St to Catherine St (2021)
  • N Maple Rd from Dexter Ave to M-14 (2017)
  • Jackson Ave from N Maple Rd to W Huron St (2015)

Take our Survey!

The A2R2 project aims to redesign ten city roads that have at least two car lanes traveling in the same direction. These roads are associated with higher vehicle speeds and carry a greater risk of severe crashes. The new designs will further the City's safety and sustainability goals by repurposing road space for pedestrian crossings, protected bike lanes, and bus priority designs. Implementing these types of design elements makes the street feel safer and more comfortable for all road users.

Completing this survey helps us understand the following:

  • How you use Ann Arbor roads.
  • How you view repurposing car lanes for safer designs.
  • What to keep in mind when redesigning these roads.

Thank you for your time.
