According to a release, the project includes several improvements including:

- Adding sidewalks, curbs and gutters, along with cycle tracks behind the roadway curb.
- Improving storm drainage to help reduce flooding.
- Adding new street lighting, transit stops, intersections and traffic signals.
- Improving access to make it easier and safer for residents to access nearby parks, trails and Osprey Marsh.
- Enhancing the culvert bridge with better waterproofing and a wider road.
This project also helps facilitate more than 3,400 housing units and will help turn Mississauga’s last remaining greenfield into transit-friendly and sustainable neighbourhood, the release adds.
The project is partly funded by the Government of Ontario’s $20 million investment through the Municipal Housing Infrastructure Program’s Housing-Enabling Core Servicing Stream.
