Fin​al Plans

Final plans have incorporated greatly improved non-motorized transportation infrastructure, such as continuous bike lanes, higher pedestrian visibility with positive contrast lighting and Rectangular Rapid-Flashing Beacon (RRFB) ​signals, and the reconfiguration of signalized intersection quadrants to allow for the future installation of Audible Pedestrian Signals (APS). 

Project ​​​Overview​

State and Hill Streets are in the heart of Ann Arbor and the University of Michigan campus. This bustling area has high levels of vehicular, pedestrian, and cycling traffic.

The City of Ann Arbor is undertaking the design and construction of crosswalk and safety improvements, road resurfacing, and water ​main upgrades on State Street from South University to Granger and on Hill Street from South Fifth Avenue to Church Street. The design process began in early 2022 and construction is expected to occur in 2023 and 2024.

The project utilizes a conglomeration of funding sources for the improvements, including the Surface Transportation Program and Highway Safety Improvement Program (HSIP) federal grants. The project abuts similar recent infrastructure improvements completed for the City and DDA.

Key goals and alignments for this project include the following:​

  • Implement safety improvements for all users of the roadway, consistent with the Moving Together Transportation Master Plan and the city's Vision Zero policy to eliminate transportation related fatalities and serious injuries.

  • Assess and implement active transportation (i.e. walking and biking) facilities along the corridor. (Implementation of Tree​line Trail Master Plan has been deemed infeasible within the scope of the project.)

  • Be responsive to the surrounding land use context, including businesses, residential areas, University of Michigan facilities, students, and event traffic.

This project will make the roadway safer, more comfortable, and more accessible for all users, while also improving utilities and roadway conditions.

​​Public Outreach​

Public Virtual Meetings have been held to share information about the project and receive community input, appropriate to the level of study and design that had been completed.  Below are links to videos of the  meetings, the presentation materials, and the  community comments and questions & answers:
