The 30-week scheme will see approaches to the M1 roundabout widened, while an extra lane will be added increasing it from two lanes to three.
In addition, new traffic signal crossings and improved cycle and pedestrian routes will be installed.
Most of the works will be carried out during the day. However, some overnight closures will be required with the first taking place between 7pm and 6am from 02 – 04 February.

Highways England project manager Derek Dobinson said: "We are investing more than £15 billion in over 100 schemes across England that will enhance, renew and improve the network. We recognise that this is an important junction which serves a major route into Leeds city centre and is the main access for a number of major businesses and that is why we are investing £8.3 million to improve it.
"This scheme, once complete, will improve capacity, reduce congestion and improve the safety for drivers. Predominantly work will be carried out during the day during off peak hours but they may be the occasional overnight closure of the slip roads and the M1."
