2026 Downtown Ann Arbor Construction

The 2026 construction season may be one of Ann Arbor's busiest to date. Long-planned capital improvements, major utility upgrades, transportation investments and private development are resulting in a significant volume of work concentrated in and around the downtown core this spring, summer and fall. Downtown Ann Arbor will remain open for business; special events will proceed; and parking structures will be accessible!

This level of activity reflects years of planning and community input. Many of the projects scheduled for 2026 are critical to maintaining safe and reliable infrastructure, meeting sustainability and mobility goals, supporting housing development and boosting Ann Arbor’s vitality. While the short-term impacts will be noticeable, the long-term benefits will serve the community for decades to come.

For details on the individual city projects in Ann Arbor, please check out Engage Ann Arbor.

Map resources

The City of Ann Arbor partners with WAZE to provide a better overview of traffic controls within the city. Visit WAZE.com or download the WAZE app.  

An interactive project map is available with detailed information. The map notes anticipated downtown road closures and can help you identify any potential impacts to your route during the busy construction season. It's important to remember, construction and closure/reopening dates may change as plans are finalized and work begins. Up-to-date information can be found by clicking any of the closures on the map, which opens a link to the projects' website.

Suggestions to help reduce aggravation:

  • Plan ahead. Determine closures that might affect your route before you get on your way. 
  • Use park-and-ride lots and take public transportation via TheRide.
  • Carpool when headed downtown.
  • Consider walking, biking or rent an e-bike/e-scooter for short trips.
  • Allow for extra travel time.
  • Park outside the most active construction zones and walk to destinations.
  • Determine in advance where to park. 

Some projects are expected to require full or partial road closures at points during the construction season. Others will require one or more lane closures. As these projects are underway in and around downtown, Ann Arbor’s annual road resurfacing and maintenance program will be underway in residential neighborhoods outside the city’s core.

Motorists driving downtown should anticipate:

  • Temporary road closures and detours
  • Slower travel times
  • Construction noise and equipment navigating streets and sites
  • Likely reductions in on-street parking

Pedestrians, cyclists and transit riders may also experience temporary rerouting around active work zones.

Transportation Projects

Utility and Road Projects

Starting May 3, 2026 construction to improve pedestrian and transit amenities between William and Liberty Streets will require the closure of Fourth Avenue and the closure of The Ride's Blake Transit Center (BTC).

For updates, including where passengers can board buses downtown, please visit The Ride's BTC update website. 

Project overview

DTE Gas will be working in Ann Arbor this spring and summer to upgrade the system that delivers safe and reliable natural gas to homes and businesses. During construction, residents and visitors will see crews and equipment on designated streets and may experience short-term changes to traffic flow, pedestrian access and parking near work areas.

Details

  • Crews from Miller Pipeline, an authorized DTE contractor, will replace cast iron and steel natural gas pipes with more efficient and durable materials that help prevent leaks and reduce greenhouse gas emissions.
  • At the same time, some indoor meters will be moved outside of homes and businesses. Outdoor meters allow technicians to perform more frequent safety inspections and maintenance and give first responders easier access should a need arise. 
  • As work progresses, temporary property repairs will be made to keep drivers and pedestrians safe. Permanent repairs to affected sidewalks, driveways, lawns and landscaping will be performed once work is complete. 

Where and when

Work is planned across the city, including downtown, the University of Michigan’s campus and surrounding neighborhoods. Construction has begun and will continue in phases Monday through Saturday from 7 a.m. to 7 p.m., as permitted by the city. Schedules may change due to weather and field conditions.
