MILWAUKEE (AP) -- The high-speed ferry that connects Wisconsin and Michigan by water is up and running for the season.

The Lake Express started on Friday, making two to three trips daily between Milwaukee and Muskegon, Mich. This is the ninth season it's been running.

Its four engines produce a total of 12,000 horsepower, allowing it to reach a speed of 40 miles per hour. It makes a one-way trip in 2 1/2 hours.

The ferry runs through October.
