LANSING — University of Michigan Health − Sparrow Lansing has released suggested alternate routes to get to its facilities as the Michigan Avenue reconstruction project moves westward.

With a new work phase expected to begin after the first week of July, the health system said patients can use Kalamazoo Street, Pennsylvania Avenue and Eureka Street to reach various facilities, including the main hospital, the Herbert-Herman Cancer Center and the Sparrow Professional Building.

The road rebuilding project began last year and is intended to make the Michigan Avenue corridor more pedestrian- and bicycle-friendly. The road is being converted from five to four lanes, with a center turn lane and one eastbound lane, with bike lanes added, sidewalks replaced and sewer and water mains upgraded, officials have said.

The project is expected to be finished in October.

Sparrow posted an advisory on its website concerning the project.

“Starting the week of July 7, the project is expected to extend from Lathrop Street west to the traffic light at Holmes and Michigan Avenue,” the health system said. “Starting in August, the project is expected to move toward the front of the hospital, where it will continue into the fall.”

A July 1 update on the city’s website said final paving of the section between Fairview Avenue and Lathrop Street was delayed until July 8-10 because of rain. That section of Michigan will be closed during that time.

“The intersections of Michigan Avenue/Clemens Avenue and Michigan Avenue/Marshall Street/Shepard Street will be closed to through traffic,” the update said. “Detours will be provided. Local access for businesses and residents will be maintained but may be limited at times.”

The city told the hospital that Phase 5 of the project (the section from Lathrop to the pedestrian bridge) remained on track to start on July 7, with pavement milling set to begin July 9.
