A project that will boost Great Lakes shipping in a crucial bottleneck and another intended to protect the lakes from invasive carp will get big funding increases under the Biden administration’s infrastructure package, officials said Thursday.

The U.S. Army Corps of Engineers said it would pump $479 million into construction of a new navigational lock at Sault Ste. Marie, Michigan, expanding a complex that enables vessels to haul bulk cargo between Lake Superior and the other Great Lakes.

Additionally, the Corps will devote $226 million to the Brandon Road Lock and Dam near Joliet, Illinois, where plans call for the installation of obstacles to prevent invasive carp from migrating up the Illinois River to Lake Michigan.

The projects have been top priorities for members of Congress from the eight states that border the Great Lakes. The infrastructure measure, which also includes $1 billion to improve water quality, makes “the single largest investment ever in the Great Lakes,” Sens. Debbie Stabenow and Gary Peters of Michigan said in a statement.

About 7,000 vessels pass annually through the Soo Locks on the St. Marys River, which connects Lake Superior and Lake Huron and has a 21-foot elevation drop. Two locks are operational but only the Poe Lock can accommodate the biggest freighters, which are around 1,000 feet long.

The industry has long pushed for another, warning that if the Poe were disabled for long, it would disrupt the transport of commodities essential to Midwestern manufacturing.

Nearly all domestically made steel used in automobiles and appliances is produced from iron ore mined in Minnesota and Michigan’s Upper Peninsula and shipped through the Poe Lock.

“The new lock at the Soo will provide much needed resiliency in the Great Lakes navigation system,” said Kevin McDaniels, deputy district engineer for the Corps’ Detroit District. “It will eliminate the single point of failure in our nation’s iron ore supply chain.”

The new funding will be enough to finish building the $1.3 billion lock, Stabenow and Peters said.

“The critical role that Great Lakes waterways play in sustaining and advancing America’s economic vitality cannot be overstated,” said Rep. Marcy Kaptur, an Ohio Democrat and chairwoman of the House Energy and Water Subcommittee.
