Current Major Closures

Lane and Ramp Closures

Highway 400 northbound and southbound, spanning from south of Langstaff Road to north of Major Mackenzie Drive, will experience temporary lane closures throughout the project’s construction. Nighttime lane closures are also expected.

These closures are necessary to facilitate the permanent widening of the highway and the replacement of existing culverts. The project aims to enhance transportation infrastructure and traffic flow.
