The investigation continues into a crash that forced the closure of a section of 402 for hours on Monday.
Lambton OPP shut down the westbound lanes between Christina Street and Front around 9:30am after two transports collided.
The crash caused a fuel leak, which prompted the arrival of the Sarnia Fire Department’s HAZ-MAT team.
No one was hurt, and the highway reopened shortly after 4 o’clock yesterday afternoon.
