It is currently unclear how many cars are involved in both accidents or if there are any injuries.
Images from the scene show westbound traffic queuing in the area as both collisions occurred in the midst of Monday's rush hour traffic.
Elsewhere, Edinburgh commuters using the M8 in West Lothian are facing delays due to a "serious" incident as emergency services have closed the motorway heading westbound between junction 4A and 5.
Road Policing Scotland tweeted an image from the scene showing the road blocked off and said the incident is '"serious" with traffic being diverted via 4A Heartlands, B7066 Harthill and re-joining the M8 at Junction 5.
Live traffic cameras from the scene show huge tailbacks starting to form around Harthill for westbound traffic, as well as queues stretching as far as Whitburn.
Police Scotland have been approached for comment.
