Fiery smash blocks traffic on busy motorway in Sydney's west

Two citybound lanes have reopened on the M4 Motorway after a multi-vehicle crash and car fire near the Ettalong Road overpass in Greystanes.

Emergency services have moved the vehicles into the breakdown lane and lane one.

Significant citybound delays continue with traffic queued over 6km approaching the incident site. 

Westbound lanes remain open, however traffic is also slow past the scene of the crash.
