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


Stadium Blvd: Tuesday, April 22 through 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.

Fourth Ave: Wednesday, April 26 through 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 through 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.

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.

Project work includes replacing a cross road culvert, widening state street and create a left turn lane for southbound State Rd Traffic.

WCRC expects that the project will be completed by 5:00 p.m., Friday, May 12, 2017. However, please be advised that due to weather conditions, all dates are tentative and subject to change.
