Environmental activists are planning events during the Labor Day Mackinac Bridge Walk to call attention to a number of issues, including a controversial oil pipeline in the area.
A group called We Protect Mother Earth says its protest will feature speeches and a drumming ceremony.
It will begin around 9 a.m. Monday at the St. Ignace Welcome Center on the north side of the bridge, where thousands of people will be taking part in the annual holiday walk.
Meanwhile, a kayak flotilla will assemble in the water near the south end of the bridge.
Participants will demand the shutdown of an Enbridge Energy oil pipeline that runs beneath the Straits of Mackinac.
Activists say it's unsafe, but the company says it has not leaked since it was built in 1953.
