City of Ann Arbor construction ​an​d traffic controls​​​​


South Main Street and East Madison Street: Tuesday, July 25–Friday, August 11, 2017. Beginning Tuesday, July 25, traffic will be restricted to one lane in each direction, on the west side of the road, between East Madison and Hill Street. The sidewalk on the east side of South Main Street will be temporarily closed between East Madison and East Mosely. Signage will be in place to alert and direct pedestrians.

South State Street: June 23-Friday, July 21, 2017. Beginning immediately, Friday, June 23, 2017, southbound South State Street north of Oakbrook Drive will be reduced to one lane until further notice for bypass pumping at the site of a sewer blockage. Northbound South State Street will not be impacted, nor will the middle turn lane. 

Pedestrian traffic will be maintained during construction. AAATA/The Ride bus stop in this area will also be unaffected. 

Catherine: Monday, June 26-TBA. *Work will be suspended for Art Fair beginning July 18 and resume Monday, July 24.

Catherine St. between North Division and North Main will be closed in the eastbound direction for resurfacing work. 

During this closure, Miller Avenue traffic approaching from the west will be detoured around the construction area and directed to use North First Street, West Ann Street, East Ann Street and North Division Street. Traffic approaching Catherine Street from the north and south on North Main Street will be directed to use East Ann Street and North Division Street. The contractor will maintain one-way traffic on Catherine Street through the construction area between North Division Street and North Main Street, with one lane operating in the westbound direction.

The contractor will maintain, and detour as required, pedestrian traffic during construction. The contractor will also maintain access for emergency vehicles. The city will prohibit on-street parking in the construction area in order to complete the work and maintain traffic.

Please see the detour map (PDF) for more detail.

Nixon/Green/Dhu Varren Intersection: June 19-September 1, 2017. Beginning on Monday, June 19, 2017, the intersection of Nixon Road, Green Road and Dhu Varren Road will be closed to traffic for construction of a new roundabout. Eastbound Dhu Varren Road and southbound Nixon Road traffic will be detoured to Pontiac Trail, Barton Drive and then to Plymouth Road. Northbound Nixon Road and westbound Green Road traffic will be detoured to Plymouth Road, Barton Drive and then to Pontiac Trail.  

Access for emergency vehicles along Nixon Road will be maintained through the construction zone. Pedestrian and bicycle traffic will be maintained.

Please see the detour map (PDF) for more detail. 

South University: Monday, June 5-Monday, July 17, 2017. Westbound South University traffic will be detoured southbound on Forest, westbound on Hill Street and then northbound on Church or Tappan while a new 12-inch water main is installed to replace the existing, corroded water main. Subsequent streetscape construction will also occur. Pedestrian through-traffic will be maintained on one side of the street at all times. Pedestrian access to businesses will be maintained with the use of temporary surfaces (e.g., rubber mats).

Stadium Boulevard Project: Saturday, June 17-TBA. On Saturday, June 17, 2017 the City of Ann Arbor will implement the Stage V traffic control plan for this project. The major element of this stage is to restrict South Main St. to one lane of traffic northbound at the Stadium Blvd. intersection. Portable message signs will have revised messages in locations that are most obvious for the upcoming change of traffic. Southbound South Main St. traffic will be detoured along Pauline Blvd. to South Seventh to Scio Church to South Main.

The project is still planned to be completed on schedule and be opened to traffic prior to the first home football game.  Also, all lanes of S. Main Street are planned to be open for the Ann Arbor Street Art Fairs.

South Division: Wednesday, May 24-Wednesday, July 19, 2017. Beginning Wednesday, May 24, 2017, a traffic shift to one side of South Division Street will occur in order to perform road resurfacing and curb/ramp/sidewalk work.  

During construction, the contractor will maintain one lane of traffic in the northbound direction through the work zone.  The full and partial closures respectively on East Jefferson, East William, East Liberty and East Washington streets at the intersections with South Division Street will require detouring traffic on to adjacent streets. These closures and detours will not occur simultaneously, and the city will issue a notice on each as they take place.

Please see the detour map (PDF) for more detail on the closure. 

South University: Monday, May 1-August 2017. *Much of the work is complete and the street will be reopened for Art Fair beginning July 19. Crews will return Monday, July 24 to complete work.

Beginning on Monday, May 1, 2017, eastbound South University between East University and Washtenaw will be closed to through traffic for streetscape improvements and underground utility work. 

Eastbound South University will be detoured south on East University, east on Willard, north on Forest to Washtenaw. Westbound traffic will be maintained.

Pedestrian thru-traffic will be maintained on one side of the street at all times.  Pedestrian access into businesses will be maintained with the use of temporary surfaces (e.g., rubber mats). Work is expected to be completed sometime in August 2017. 

Green Road, north of the Plymouth Road intersection: Thursday, June 8-Friday, August 4, 2017. Beginning on Thursday, June 8, 2017, Phase 1B of construction work will be added to the Phase 1A (described below) currently in place, and the traffic on Plymouth Road at its intersection with Green Road will be reduced to one lane westbound and two lanes eastbound. In addition, the left turning traffic from  east and west-bound Plymouth Road onto Green Road will be directed to Commonwealth Blvd. and then to Green Road. 

Phase 1A Traffic Control Plan: Currently, the traffic on Green Road at its intersection with Plymouth Road is reduced to one lane in each direction. In addition, the left turning traffic from south and south-bound Green Road onto Plymouth Road is directed to Commonwealth Blvd. and then to Plymouth Road. A temporary traffic signal was installed at the intersection of Plymouth Road and Commonwealth Blvd.  This traffic control will remain in place through this phase.

Pedestrian and bicycle traffic will be maintained.

These traffic controls are necessary for urgently needed water main replacement and repaving work.
