Windsor Street Exchange project advances to second development phase

On Wednesday, the Halifax Regional Municipality announced that the Windsor Street Exchange development project would be moving on to phase two.

As many Halifax drivers are aware, the first phase of construction of the Windsor Street Exchange began in fall 2025. According to a press release from the city, this phase focused primarily on enabling detours, retaining walls, underground utilities, site preparations and foundation activities.

The real work on the exchange will begin in the second phase, when construction of a new overpass will begin. The municipality says this overpass will allow for “efficient, uninterrupted movement between the Bedford Highway and Highway 11/the MacKay Bridge.” It also promises to reconfigure intersections on the Bedford Highway, Windsor Street and Lady Hammond Road for safety and to reduce congestion.

A new exit is also promised to be added to Bayne Street, allowing traffic to flow in and out of the Port of Halifax with ease. It will also improve signal intersections and Halifax Water infrastructure.

The estimated cost of the project is around $180 million, funded between the municipality, the federal government, the province, Halifax Water and the Halifax Port Authority. Here’s the breakdown of how much each entity is contributing.

• Halifax Regional Municipality: $85.75 million
• Halifax Water: $60 million
• Transport Canada: $23.5 million
• Province of Nova Scotia: $10.75 million
• Halifax Port Authority: $2 million

Construction is expected to continue until 2029. The city expects most of it to be completed by the summer of that year, but the full project won’t be finished until the end of 2029.
