A chain reaction crash that involved four tractor trailers and a dump truck caused some traffic headaches in London.
OPP say the morning commute for people heading east on Hwy. 401 was disrupted by a mutli-vehicle crash at Highbury Ave just before 7am Wednesday.
One of the transports was slowing down for construction when it was rear-ended. That started the chain reaction crash involving the other tractor trailers and the dump truck. One person was taken to hospital with minor injuries.
Police had to close two lanes, causing a significant logjam on the highway.
The lanes have since cleared.
