Project Limits

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 St​ate 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.​

Current work - updated Feb. 29, 2024

The State and Hill Streets Improvements Project is scheduled to resume on Monday, March 4, 2024. The project includes utility, road, signals and sidewalk improvements.​

General Information​
Normal work hours are to 7 a.m. to 8 p.m. Monday thru Saturday. Contractor operations beyond those hours, or on Sunday, would only be allowed if there is critical work that needs to be completed.

The construction work unavoidably generates dust and noise, as well as inconveniences. We would like to thank you in advance for your patience and cooperation during the project.

For any on site questions, please contact Erik Rehkop at 231.580.9663 or Brian Schert at 313.363.6150. 

Schedule and Phasing
This year, the construction will be on Hill Street from Fifth to Church, in varying segments as Phases 4-6, from March through August.

  • Phase 4 (Hill Street Utility Work and Partial Restoration) 3/4 - 6/14
    Hill Street, Fifth to State closed. The Division, Sybil, and Packard intersections will also be closed. Only southbound traffic on State Street will be maintained through Hill. On Division, between Hill and John, and on Sybil, between, Hill and Benjamin, parking will be restricted and two-way traffic will be permitted.
    During this phase, Packard to State will be permanently restored (curb, pavement, pavement markings).

  • Phase 5 (Hill Street Utility and Complete Restoration) 6/17 - 7/12
    Hill Street, Fifth to Packard will be one-way with eastbound traffic maintained.
    During this phase, upon completion of remaining utility installation, Fifth to Packard will be permanently restored (curb, pavement, pavement markings).

  • Phase 6 (Hill Street Resurfacing) 7/22 – 8/16
    Hill Street, State to Church will be one-way with eastbound traffic maintained.
    This phase is primarily about resurfacing from State Street to Church Street, which includes some curb and sidewalk, pavement, pavement markings.

Water Main Construction 3/4 - 6/14
Water service will generally be maintained during construction with a few exceptions:

  • A planned water service interruption may last several hours when the new water mains are tied into the existing mains. Orange door-hanger notifications will be distributed at least a day in advance.

  • A brief water service interruption, of about 30 minutes, when a water service is transferred to the new main. In person notification at the door will occur immediately prior to the brief interruption.

Due to the need for the city to open and close water main valves in the vicinity of the project, it is normal for some sediment in the water mains to be disturbed. As a result, you may observe that your water appears cloudy or rusty. While undesirable, the sediment is not harmful, and can be cleared by running cold water for several minutes. It is recommended that you run water from a basement faucet, or the lowest location in your residence.

Access and Typical Services
Local access for vehicular and pedestrian traffic will be maintained. Contact onsite workers if your destination appears inaccessible. Access to driveways will be maintained except for brief periods when the construction work (e.g. excavation) is in the immediate vicinity of the driveway. The contractor is expected to provide appropriate notification.

During the pavement construction, however, there will be unavoidable disruptions to street and driveway access; properties will be notified of expected time and duration of inaccessibility. Depending on the ambient temperature, concrete can take 2-3 days to cure and asphalt takes several hours to cool. Commercial driveways can be completed in half-widths to maintain access if another means of access is unavailable. The contractor will coordinate these interruptions with the property users.

Trash and recycle collection, emergency vehicle access, and mail/shipping deliveries will be maintained throughout the project.

Deliveries using semi-trailers
Deliveries will be accommodated within the vicinity of the businesses to every extent practicable, but the traffic control may affect typical routes and unloading locations used by larger delivery vehicles. We request that scheduled deliveries of this nature be coordinated with the Project Manager or on-site staff to ensure that needs are met.​​

Costs and funding sources

The project utilizes a conglomeration o​f 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.
