POLICE are dealing with a security alert on the M1 motorway on Monday morning – the third in a week.
The motorway has been closed in both directions between the Lisburn/Saintfield turn-off and at Stockman’s Lane.
A diversion is in place via Stockman’s Lane and the Saintfield Road junction at Lisburn.
The M1 was closed following the alert on the Black’s Road off-slip in west Belfast.
The alert is also causing severe tailbacks leaving the M1 at Moira as drivers try to take an alternative route via the A26 through Nutts Corner.
There is a tailback of city-bound traffic back to Lurgan and country-bound to the Broadway roundabout.
There are also delays for traffic coming into Belfast on the Lisburn road, Andersonstown Road, the Hillhall Road, Upper Malone Road and Milltown Road.
There was a similar alert on Saturday which forced delayed kick offs to two Irish League matches.
It was declared a hoax.
And last Monday there was massive tailbacks for commuters on the M1 with another hoax alert.
