Overview
- Contractors discovered a sinkhole Thursday evening in the northbound slow lane during Trans Mountain pipeline boring work.
- Northbound lanes closed Thursday night were expanded to both directions by Friday at 9 p.m. when assessments revealed broader pavement instability.
- The southbound fast lane was shut Friday afternoon as a precaution while crews investigated potential damage across the highway.
- Unforeseen geotechnical complications pushed back the hoped-for midday reopening to an estimated 7:30 p.m. Saturday.
- Drivers were detoured onto Highways 1 and 3 with the Ministry of Transportation and DriveBC issuing traffic updates throughout the closure.
