LS Marine, Inc., of Inver Grove Heights, Minnesota, recently won a $31.7 million contract from the U.S. Army Corps of Engineers to conduct mechanical dredging operations in support of channel maintenance within the Mississippi River.
This work will facilitate long-term channel maintenance dredging and placement of dredged material, or river sand, for the Upper Mississippi River System 9-foot navigation channel.
Dredging will include parts of the Upper Mississippi River, the Minnesota River, the St. Croix River and the Black River within the St. Paul District. Additional dredging of the Upper Mississippi River in the Rock Island District may also be covered.
The contract provides a minimum guarantee of $1.25 million for two mechanical dredging plants through the end of the 2024 navigation season, with rights to exercise work options through 2029. The four additional years of maintenance dredging ensure the navigation channel remains open for the foreseeable future.
LS Marine is expected to begin work after plant mobilization in the coming weeks.
