Construction is officially underway on a major infrastructure project that will transform a key stretch of Ninth Line in west Mississauga, making it safer, more efficient and better equipped to support future growth.
City officials marked the start of construction today with a groundbreaking ceremony for the Ninth Line Road Widening project between Eglinton Avenue West and Derry Road West. The project will upgrade a 6.7-kilometre section of roadway and is expected to be completed in 2027.
“We are building road infrastructure for more than just drivers in their cars, but to also support pedestrians, cyclists and transit riders,” said Sam Rogers, commissioner, transportation and works. “This project is also aligned with our Vision Zero framework with the long-term goal of zero traffic-related fatalities and serious injuries in our city.
“This type of muti-modal infrastructure highlights how community feedback and a robust planning process can make an impact for those travelling along this major corridor, now and in the future.”
The improvements are designed to accommodate growing transportation needs while supporting the development of more than 3,400 new housing units in the area. Once complete, the upgraded corridor will provide safer and more convenient travel options for motorists, cyclists, pedestrians and transit users.
“Ninth Line is no longer a rural road on the outskirts of the city; it is becoming a critical artery for the Erin Mills community,” said Sheref Sabawy, Member of Provincial Parliament for Mississauga-Erin Mills. “In recent years, we have seen incredible community milestones come to life here, including the Churchill Meadows Community Centre and Mattamy Sports Park.
“Expanding Ninth Line will allow development to continue, paving the way for new homes and development in the community we love.”
Key elements of the project include widening Ninth Line from two lanes to four lanes, with two lanes in each direction to improve traffic flow and reduce congestion during peak travel periods.
New sidewalks, curbs and gutters will be installed along the corridor, while protected cycle tracks will be added behind the roadway curb to provide safer routes for people walking and biking. The project will also introduce upgraded transit stops, new street lighting, additional traffic signals and improved intersections.
To address weather-related challenges, the City will enhance stormwater infrastructure and improve drainage systems to help reduce flooding during heavy rainfall events. A culvert bridge along the corridor will also be upgraded with improved waterproofing and a wider roadway to increase resilience during storms.
Residents will benefit from improved access to nearby parks, trails and Osprey Marsh, creating safer and more convenient connections to local recreational spaces.
Beyond transportation improvements, the project is expected to play a significant role in shaping Mississauga’s last remaining greenfield area into a well-connected, transit-friendly and sustainable neighbourhood.
City officials say the upgrades will not only improve daily travel for existing residents but also ensure the transportation network can support continued growth in the years ahead.
