Multiple landslides have forced the closure of northbound I-5 south of Bellingham, Washington, disrupting traffic and commerce. While emergency crews work to clear the debris, experts warn that the crisis reveals deeper issues with the state's infrastructure and its ability to withstand extreme weather events potentially linked to climate change.

Why it matters

The I-5 closure is more than just a local traffic headache - it's a stark reminder of how vulnerable our transportation networks are to the impacts of severe weather and natural disasters. This crisis underscores the need for proactive investment in resilient infrastructure that can adapt to a changing climate.

The details

Geotechnical engineers must first stabilize the slope before cleanup can begin, highlighting the need for a preventative approach rather than just reactive measures. The reliance on a single critical corridor like I-5 has also exposed the lack of diversified transportation options, with freight traffic struggling on recommended detours like Valley Highway and Chuckanut Drive.

  • On March 21, 2026, multiple landslides shut down northbound I-5 south of Bellingham.
  • Emergency contracts have been announced to clear the roadway, but the work cannot begin until the slope is stabilized.

What’s next

Geotechnical engineers will need to stabilize the slope before cleanup and repairs can begin on the northbound lanes of I-5.

The takeaway

This crisis highlights the urgent need for proactive investment in resilient transportation infrastructure that can withstand the impacts of climate change and extreme weather events. Relying on a single critical corridor like I-5 leaves the state vulnerable, underscoring the importance of diversified transportation networks and a shift in how we view infrastructure as a long-term investment rather than a short-term expense.
