Barnet's motorists will have a road closure to avoid nearby on the National Highways network this week.
And it is expected to cause delays of between 10 and 30 minutes.
The latest expected works list, with notes from National Highways, shows that one closure is due to start this week:
• A1, from 10pm July 4 to 5am July 6, moderate delays (10-30 minutes): M1 northbound, junction 2, entry slip road closure for barrier repairs, diversion via TFL roads (A41 to junction 4).
National Highways is responsible for maintaining motorways and major A-roads, so closures of smaller roads will not be included in their schedule.
