The Cogswell Interchange was a multi-level highway interchange in downtown Halifax, Nova Scotia, Canada. It was built as the first stage of a greater scheme for an elevated freeway, called Harbour Drive, which would have run south through downtown and necessitated demolition of much of the downtown building stock. The plan was halted in the face of significant public opposition, but the Cogswell Interchange remained a visible reminder, occupying a large amount of prime land and posing a barrier to pedestrian movement.
As the interchange became functionally obsolete and increasingly expensive to maintain, the municipal government decided to demolish the interchange and replace it with a more conventional street grid. Halifax Regional Council unanimously approved the 90 per cent design construction plan in February 2019 and directed staff to tender demolition and construction contracts for the redevelopment. Work began on the project in March 2022 and the newly renamed Cogswell District is scheduled to be open to the public by late 2025.
