VANCOUVER, Washington — October 24, 2026. A federal lawsuit could affect the Interstate Bridge Replacement project, one of the Pacific Northwest’s largest transportation plans. Iron Partners LLC, which owns industrial property on Vancouver’s waterfront, says the proposed replacement for the I-5 bridge would restrict river navigation and harm businesses upstream.
The company filed suit on October 6. According to Portland Business Journal and The Center Square, it challenges the federal environmental and navigation reviews behind the choice of a fixed bridge with 116 feet of vertical clearance. Iron Partners seeks to block demolition of the existing bridges and construction of replacements until further analysis is completed. Filing the lawsuit has not, by itself, stopped the project.
Why 116 feet matters
The current I-5 crossing has lift spans that can open for tall vessels and oversized industrial loads. A lift interrupts highway traffic, but it also gives river users more room. The replacement plan calls for two parallel fixed bridges with 116 feet, roughly 35 meters, of clearance. The existing bridge provides about 178 feet, or 54 meters, when fully lifted. That is a difference of 62 feet, nearly 19 meters.
Most river traffic may be able to pass beneath the fixed span. Companies that move large steel structures and specialized vessels say some of their shipments need more space. This is the core of the dispute.
Iron Partners and its river access
Iron Partners owns about ten acres at Columbia Business Center, 3515 SE Columbia Way in Vancouver, about two miles upstream of the proposed crossing. Its Building 48 is equipped for heavy manufacturing, with two 80-ton cranes and a 25-ton crane, according to company documents. The business uses the Columbia River to move large metal structures.
In comments submitted to the U.S. Coast Guard on July 25, 2026, the company said a lower bridge could limit its ability to perform major contracts for energy, infrastructure, defense and other industries. It says there is no alternative river route around the bridge. Those are the company’s claims; their merits and any potential damages remain for the legal process to determine.
Construction could also create restrictions
Iron Partners says the issue is not limited to the finished bridge. Temporary navigation channels and work-zone restrictions during construction could also prevent high or oversized cargo from moving along the river. The company argues that it must know whether it can deliver a product before bidding on long-term industrial contracts. The potential impact therefore extends through the construction period as well as the life of the bridge.
Why planners chose a fixed span
The Interstate Bridge Replacement Program is a joint effort by Washington and Oregon to replace aging infrastructure, improve traffic safety and seismic resilience, and expand transportation options. The proposed bridges would carry vehicles, pedestrians and cyclists, with a possible light-rail extension across the river. Project planners say a fixed span would remove the lift mechanism and the traffic stops it causes.
On January 16, 2026, the U.S. Coast Guard announced a decision allowing a fixed bridge with 116 feet of clearance. The replacement program says that height would accommodate more than 99% of existing river traffic. Iron Partners argues that the remaining traffic can include unusually large shipments that matter greatly to specific businesses. Vessel counts alone may therefore miss the economic impact of restricted shipments.
Other businesses reached agreements
The clearance issue predates this lawsuit. The program previously announced agreements with Thompson Metal Fab, Greenberry Industrial, Advanced American Construction and JT Marine, businesses whose shipments could be affected by a lower span. The agreements total about $141 million. Iron Partners is not among them. Their existence shows that industrial navigation effects were part of project planning, but whether all affected interests have been adequately addressed remains disputed.
What the lawsuit alleges
Iron Partners argues that federal transportation agencies did not sufficiently study the effects of reduced clearance. It says the environmental review failed to account fully for some vessels requiring more height and did not adequately examine alternatives such as a movable span. Its claims invoke federal environmental and bridge laws. These are allegations, not findings by a court.
The Interstate Bridge Replacement Program told The Center Square it could not comment on ongoing litigation and referred questions to the federal agencies involved.
What happens next
The outcome depends on the federal court and agencies responsible for design, permits and construction. The replacement program still plans fixed-span bridges. Oregon’s Department of Environmental Quality says construction is expected to begin in 2028, subject to required approvals. The lawsuit alone has not changed that timetable; stopping construction or revising the design would require further decisions.
The region needs a safer, more resilient crossing, while the Columbia River remains an industrial shipping route. The Iron Partners case shows how difficult it can be to satisfy both needs in one project.
WE PNW will follow the litigation, official decisions and any changes to the I-5 bridge plan.
