Wicklow County Council is expected to invest somewhere in the region of €1 million to €1.2 million on the project, which will significantly upgrade pedestrian and cyclist safety in the area.
Officials plan to engage with local people, during a non-statutory consultation period.
If all goes to plan, Wicklow County Council hope to carry out the work by early October.
Some of the crossings expected to be improved include the Knockroe roundabout, and the crossing between Charlesland Shopping Centre and Charlesland Wood.
The funding is expected to be sourced from the Greystones Pathfinder Project which has a budget of €1.5 million.
The Pathfinder project needs to be completed by 2025.
Cllr Stephen Stokes stated: "A lot of the planned investment on the Charlesland Dual Carriageway area will be spent on the lights. They are quite expensive. People write to me regularly about road safety, so hopefully this will make a positive impact."
