WHAT ARE WE DOING?

As our waterfront construction continues in a portion of the Menominee River adjacent to the shipyard, we need to limit river traffic in this specific location for a few minutes each weekday afternoon from 4 – 5 p.m. CT, so that large sections of bedrock can be broken up and safely removed.

Our work along our waterfront must be accomplished from late spring to mid-Autumn.  We have coordinated with the Army Corps of Engineers, local law enforcement, the U.S. Coast Guard, the cities of Marinette and Menominee, and the Wisconsin Department of Natural Resources to facilitate our activities in a safe and responsible manner.

This work is required for FMM to build and deliver larger vessels under contract with the U.S. Navy.  We appreciate your patience and endeavor to minimize the impact to those who enjoy the Menominee River as much as we do.  Keep in mind that the Menominee River will be open for all traffic and activities every day, except for a few minutes each weekday afternoon. We plan to limit construction activities to weekdays only, and we will observe holidays.

Check out the detailed maps below to determine which areas of the Menominee River will be temporarily restricted during times of construction and blasting.”
