South Fourth Ave.: Saturday, August 19, 2017, 7 a.m. - 8 p.m. South Fourth Ave. between Huron and Washington will be closed to vehicle traffic for work on the 100 block of South Fourth. As a result, a traffic detour (PDF) will be in place. 

Southbound Fourth Avenue will be detoured east on Huron Street, south on Fifth Avenue, and west on Washington Street. Northbound Fourth Avenue will be detoured west on Washington Street, north on South Main Street and east on Huron Street. Pedestrian traffic on the east side of Fourth Avenue will be detoured to the west side of Fourth Avenue.

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.

Catherine Street: Monday, August 14-Friday, August 25, 2017. Beginning Monday, Aug. 14, 2017, Catherine Street will close in the eastbound direction between North Main and North Fifth Ave. During this closure, Miller traffic approaching from the west will be detoured (PDF) around the construction area and directed to use North First, Ann and North Division. Traffic approaching Catherine from the north and south on North Main will be directed to use East Ann and North Division. In addition, Catherine will close in the eastbound direction between North Ingalls and Glen, with traffic being detoured around this closure using East Ann. The contractor will maintain one-way traffic on Catherine through the entire construction area between Glen Avenue and North Main, 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 construction area in order to complete the work and maintain traffic.

South Forest Avenue: Friday, July 28-Monday, Aug. 14, 2017. Work has resumed on South Forest Avenue between Washtenaw Avenue and South University. Underground water main and storm sewer utility are being installed, associated with the South University Streetscape/Water Main Project. The project, which began in May, had been paused during the Ann Arbor Art Fair. Southbound South Forest is being detoured south on Washtenaw to west on South University. Northbound and local traffic is being maintained, as is pedestrian through-traffic on one side of the street. (Note, this closure does not yet appear on the Waze map above.)

Huron Parkway: 9 a.m.-3:30 p.m. Monday, July 31-Friday, Sept. 15, 2017. The City of Ann Arbor will be performing minor rehabilitation work to the existing segmental block walls along Huron Parkway from approximately 1,000 feet south of Washtenaw Avenue to East Huron River Drive in order to keep them in a state of good repair. The work to be performed consists of removing and replacing the cap units, cleaning the walls and installing a sealer on the walls to help prevent damage from road salt. Only one lane of traffic will be closed at any given time during the non-peak travel hours of 9 a.m.–3:30 p.m. Monday through Friday during the course of the project. It is expected that the contractor will first work on the westerly side of Huron Parkway to complete repairs and then switch their operations to work on the easterly side of the roadway. Huron Parkway will not be obstructed during the morning or evening rush hours during the project. It will also be necessary to close the sidewalk on the side of the roadway on which the contractor is working in order to allow the room needed to safely perform the work. (Note, this closure does not yet appear on the Waze map above). Please see the area map (PDF) for more detail. (Note, this closure does not yet appear on the Waze map above.)

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. 

Stadium Boulevard Project: Saturday, June 17-TBA On August 7th, E. Stadium Boulevard between S. Main Street and the E. Stadium Boulevard Bridges was reopened to two-way traffic.  Currently, the roadway has temporary striping and the center turn lane is closed.  The permanent striping will take place once the paving has been completed on the westerly portion of the Stadium/Main intersection. The sidewalks and on-street bicycle lanes along both sides of the roadway are now open to traffic. Since Stadium Boulevard west of Main Street is still closed to through traffic, westbound traffic on Stadium is still being detoured along the posted detour route (PDF) that has been in place since the beginning of the project.  Attached, please find a copy of the detour map that is currently in place.

The current phase of the project is scheduled to be completed by August 21, 2017, however it does not appear that the contractor will complete the work by this date.  However, it is expected that the work will be completed and the roadways fully open to traffic (weather permitting) prior to the first University of Michigan home football game which is to be played on September 9, 2017. 

All underground utility work for this stage of the project has been completed.  The Contractor is currently working to place the sand subbase and aggregate base course for the westerly portion on the intersection.  Placement of the concrete pavement is scheduled for later this week and should be completed in about seven to ten days, plus the required time for the newly placed concrete to cure.  Once the concrete pavement has been placed, the contractor will finish the concrete sidewalk, communications conduits, and street lighting.

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-end of September, 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.
