Highway 407 East

Air quality, noise and vibration assessments for a 46-kilometer highway expansion

Highway 407 is a major artery in Southern Ontario, running east-west above the northern edge of Toronto. One part of the project adds a total of 46 kilometers to the area’s highway network. To proceed, the project required significant air quality, noise and vibration studies and mitigation plans. Our work helped the 407 East project to meet the rigorous environmental requirements of two levels of government and earn approval to proceed with construction. During construction, we helped the design/build team meet their conditions of approval and ensure an environmentally sound project. We also assisted with potential snowdrift issues by completing a snow study and proposing mitigation strategies.
