For more than fifty years, a massive boulder beside northbound I-5 in Bellingham has served as the city’s unofficial community billboard — painted over and over with birthdays, memorials, proposals, and protests until the layers ran thick enough to require hazardous materials removal.
Now construction crews are preparing to break it apart.
The reason sits underneath the highway: a network of aging culverts blocking salmon from reaching upstream habitat. Fixing them is a legal requirement, and Bellingham Rock sits directly in the way — caught between a community’s attachment to an accidental landmark and a federal court order that has been reshaping Washington’s roadsides one creek at a time.
A landmark born from the interstate
Bellingham Rock didn’t start as a landmark. It was just a boulder — a large one, sitting beside the highway. Over five decades, the community claimed it. Graduation announcements, wedding proposals, memorials, sports victories: the paint layers accumulated year after year until the rock functioned less like a geological feature and more like a public institution.
WSDOT recognized that significance early. In 2023, the agency conducted fieldwork formally documenting the rock as a unique geological feature used for decades as a community message space. That documentation fed into required environmental and cultural resource reviews — a structured process evaluating how construction would interact with the rock and what options existed to avoid, minimize, or mitigate the impact. The conclusion was unavoidable: the rock sits directly within the construction footprint at Chuckanut Creek, and leaving it in place wasn’t feasible.
Why the rock has to move: salmon, culverts, and a court order
The legal backdrop matters here. A federal court injunction requires Washington State to remove fish passage barriers created by state-owned culverts — structures blocking salmon and steelhead from reaching upstream habitat. That obligation has been reshaping highway infrastructure across the state for years.
The stretch of I-5 near Bellingham is one node in that larger effort. Crews are replacing 17 outdated culverts under the highway near Lake Samish with 10 new structures designed to let fish move freely, spanning Lake, Friday, and Chuckanut creeks. Once complete, the work will open nearly three-quarters of a mile of additional upstream habitat for salmon and steelhead.
Federal Highway Administration rules add another constraint. They prohibit returning the rock to limited-access corridors like I-5 or nearby ramps, where it could encourage unsafe stopping or pedestrian access. Once it leaves, it can’t come back to the roadside.
Breaking apart a 100-ton boulder
The removal process is more involved than simply loading a rock onto a flatbed. At more than 100 tons, the boulder can’t be moved intact without specialized equipment, permits, and significant cost — so it’ll be broken apart, carefully, in stages.
The first step is the paint itself. Decades of layers mean some of it is likely lead-based. Beginning as early as April 13, crews will chip paint from the surface using small tools, potentially supplemented by specialized chemicals to dissolve remaining layers. Soil around the rock — up to two feet deep in some areas — will also be removed to address contaminants including lead and cadmium, then disposed of at permitted facilities.
Once the surface is cleared, crews will drill holes into the rock and use expansive grout to slowly create fractures, repeating the process until the boulder breaks into pieces small enough to load onto trucks. No explosives will be used. Travelers on northbound I-5 near the North Lake Samish exit should expect periodic right-lane closures during this phase, which could begin as early as April 20.
Where the rock goes next
Finding a destination for a fragmented 100-ton community landmark proved harder than it sounds. WSDOT evaluated publicly owned sites, but each ran into practical barriers: access limitations, environmental and safety concerns, long-term maintenance responsibilities, or insufficient infrastructure for public visitors. No public agency stepped forward to take ownership.
That left private placement as the only viable path. A Bellingham landowner has signed an agreement — reviewed by the Attorney General’s Office — to accept the pieces and maintain public access. The arrangement includes a contingency: the owner will inspect the fragments after removal and can choose whether to accept final possession. If they decline, WSDOT plans to develop a process for distributing pieces to interested community members. The agency is also documenting the rock’s history as part of the removal process, preserving some record of what it represented even as the physical object is dispersed.
A broader transformation along I-5
The Bellingham Rock story is unusual, but the underlying project isn’t. The fish passage work at Lake, Friday, and Chuckanut creeks is part of WSDOT’s statewide program — a long-running, court-driven effort to reconcile decades of highway construction with the ecological systems those roads disrupted.
At Chuckanut Creek specifically, the project includes building three new bridges along northbound and southbound I-5 and Old Samish Road. During late spring and summer construction, I-5 traffic in both directions will shift to temporary two-lane bypass roads, and Old Samish Road will close temporarily while a new bridge is built over the creek.
The Bellingham boulder happened to be in the way — a community artifact caught inside an infrastructure obligation that predates any single project or administration. What its removal invites us to consider is something older than the injunction or the culverts: how much of what we call a landmark is the object itself, and how much is simply the habit of gathering around it? The paint will be stripped, the stone broken, the pieces scattered. Whether the community finds a new surface — or decides it doesn’t need one — may say more about Bellingham than the rock ever did.
