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


Stadium Boulevard: Tuesday, April 22-Monday, May 8, 2017. The City of Ann Arbor is continuing its reconstruction of Stadium Blvd between South Main St and South Industrial Hwy. To this end, beginning on Saturday, April 22, 2017, (weather permitting) the contractor for the project, Dan's Excavating Inc., will implement the Stage III traffic control for the project in order to construct a 30" and 12" water main across the west half of South Main St. This stage of the construction is expected to last approximately two to three weeks. Immediately after this is completed, the contractor will implement Stage IV of the construction and connect the new water mains into the existing water mains west of South Main St.

East Stadium Blvd will be completely closed to through traffic between South Main St and South Industrial Hwy. We will be maintaining local access to Kipke Drive, the University of Michigan's Golf Course (Blue Course), and the Ann Arbor Golf and Outing Club.

The detour will commence at the East Stadium Blvd/South Industrial Hwy intersection and proceed south on South Industrial Hwy to Eisenhower Pkwy, thence west along Eisenhower Pkwy to South Main St, thence north along South Main St to Ann Arbor-Saline Rd, thence continuing northerly along Ann Arbor-Saline Rd to South Main St, thence east along Scio Church Rd to South Seventh St, thence northerly along South Seventh St to the West Stadium Blvd/South Seventh St intersection.

Eastbound traffic travelling along West Stadium Blvd that wishes to access South Main St will be directed to northbound South Seventh St to eastbound Pauline Blvd to South Main St. This will be done through the use of digital message boards displayed in and around the project area.

A map of the Stage III Detour Plan (PDF) is available. Planned traffic movement changes (PDF) will also be in place at the South Main Street/Stadium Blvd intersection during this stage of construction.

East Liberty at South Division: Tuesday, May 30-Friday, June 9, 2017. Beginning Tuesday, May 30, 2017, East Liberty St. will close in the eastbound direction at South Division for road reconstruction and other improvements. During the closure, traffic will be detoured around the construction area from one block to the west and directed to use South Fifth Avenue, East William Street and Thompson Street. The contractor will maintain one-way traffic on East Liberty Street through the construction area, with one lane operating in the westbound direction.

The contractor will maintain, and detour as required, pedestrian traffic during construction. Access will also be maintained for emergency vehicles. The city will prohibit on street parking in construction areas, and as required to maintain traffic.

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

South Division: Wednesday, May 24-Saturday, July 8, 2017. Beginning Wednesday, May 24, 2017, a traffic shift to one side of South Division St. 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 St. 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. 

Arlington Blvd: Monday, May 15, 2017 until further notice. Beginning Monday, May 15, 2017, Arlington Blvd. will be closed to traffic in the northbound direction between Washtenaw Ave. and Heather Way for resurfacing, drainage improvements and curb and gutter work. 

During this time, northbound traffic will be detoured westerly on Washtenaw Avenue and easterly on Hill St. and Geddes Ave. back to Arlington Blvd. One-way traffic on Arlington Blvd. will be maintained through the work zone with one lane operating in the southbound direction of travel.

Please see the detour map (PDF) for possible alternative routes. 

Fourth Avenue: Wednesday, April 26-Monday, July 17, 2017. Beginning on Wednesday, April 26, Fourth Ave between Liberty and Washington will have parking removed from both sides of the street and the west lane will be closed to traffic. Two-way traffic will be maintained by shifting both lanes of travel east. The lane shift is necessary for construction work on the 200 block of South Fourth Ave. The lane shift will be removed on July 17, 2017. 

South University: Monday, May 1-August 2017. 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.

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.
