BELLINGHAM, Wash. — Crews working on the March 19 landslide south of Bellingham made a major breakthrough April 1, splitting what officials described as a “bus-sized” rock at the center of the debris field.
That boulder had been a key obstruction slowing progress. Its removal marks a significant step toward clearing the roadway. However, the focus remains on preventing another collapse.

Crews continue drilling into the hillside and installing steel dowels to stabilize the slope above northbound Interstate 5. Engineers are adjusting the plan in real time based on ground conditions.
As a result, the timeline to reopen the highway still depends on slope stability, not just debris removal.
Northbound I-5 remains closed at Exit 246 near North Lake Samish Road. Drivers should continue using designated detours and follow proper zipper merge etiquette to reduce congestion.
