2026 Greater Downtown Construction Season

Ann Arbor’s 2026 construction season will be one of the busiest in recent memory. A convergence of long-planned capital improvements, major utility upgrades, transportation investments, and private development will result 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.

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

Construction inevitably creates inconvenience. However, it also presents an opportunity to rethink how we move around the city.

To lessen the likelihood of aggravation, residents and visitors are encouraged to:

  • Plan ahead. Determine what closures might affect your route before you get in your vehicle. Use online routing tools, like WAZE, to be routed around closures.
  • Use park-and-ride lots and take public transportation via TheRide
  • Carpool when headed downtown with others.
  • Consider walking, biking or using micromobility options for short trips
  • Allow for extra travel time
  • Park outside the most active construction zones and walk to destinations
  • Determine in advance where you plan to park.
