A temporary 50mph speed limit placed on the M1 between Dungannon and Tamnamore in January has been extended for at least another three months.
The speed measures were introduced on the eastbound carriageway between junctions 14 and 15 as part of PSNI and Department for Infrastructure investigations into two separate fatal crashes involving single vehicles last year.
A spokesperson for the Department for Infrastructure said the speed restriction would continue and that it was enforceable by the PSNI.
