Why is this project being done?

The East Medical Center Drive Bridge over the Amtrak Michigan line was constructed in 1982 and is now being inspected every twelve months due to its deteriorating condition. It was the City's intent to rehabilitate the Bridge in order to return it to a State of Good Repair and prolong its life span. The University of Michigan was also interested in partnership for this project and to widen the bridge in order to improve traffic flow into and out of the Medical Center.

Funding sources

• City of Ann Arbor Street, Bridge and Sidewalk Millage Fund
• The University of Michigan

Total Costs: $15 million

• Temporary lane closure and sidewalk closures; detours will be posted on the City of Ann Arbor's road and lane closures page and University of Michigan Construction Alerts Notices page.
• One lane of traffic in each direction will be maintained on East Medical Center Drive Bridge at all times; however, lanes may shift as the construction of the bridge will be done part width – west side first, then east side.
• Construction will unavoidably generate dust and noise and many other inconveniences. In addition, you may see construction equipment, signs relocated, utility flags, surveyor stakes, and protection fences located along the roadway which are important to construction and should not be disturbed.

The project team will make every effort to communicate traffic control changes and detours to the general public, residents, hospital staff and patients.
