Two crashes along the M7 in Sydney's west on Thursday afternoon have led to traffic gridlock as commuters attempt to head home during the evening peak hour.
The crashes, one between a car and truck and a second between multiple vehicles thought to be trucks, were just one kilometre – and about 40 minutes – apart, at Eastern Creek.
A third crash nearby shortly after 4pm, on the M4 at Minchinbury, has only added to the traffic headaches.
There are currently 14-kilometre queues on the M7, with one southbound lane closed. Traffic is affected in both directions.
