The junction will be repaired and resurfaced using high friction material to reduce the likelihood of accidents.
Developed in conjunction with the London Borough of Barnet, new signal-controlled crossings will also be installed, making crossing the road easier for pedestrians and cyclists.
The crossings will be automated during the Jewish Sabbath, from Friday evenings to Saturday evenings, to meet the religious requirements not to use electricity.
Preliminary work on footways will start this week with main carriageway improvements starting in Aptil for completion at the end of the year.
