On this day in 1917, the text of the so-called Zimmermann Telegram, a message from the German foreign secretary, Arthur Zimmermann, to the German ambassador to Mexico proposing a Mexican-German alliance in the case of war between the United States and Germany, is published on the front pages of newspapers across America.
The work is part of a larger project to improve County Road 4 and the Highway 169/County Road 4 intersection in Zimmerman. The project is being led by Sherburne County. For more information, contact Sherburne County or visit www.co.sherburne.mn.us/publicworks/transport/constructionProjects.php.
