Highway 104 Port Hastings roundabout

Government is upgrading the existing Port Hastings rotary to a modern roundabout to improve safety and standardize it with other roundabouts in the province. Planning and preliminary design work is currently underway. Construction is expected to start in summer 2021, ending in 2022. are underway in preparation for clearing scheduled for spring 2019.

Project description

The proposed project includes a roundabout built near the location of the existing rotary and a new storage lane for vehicles approaching the Canso Causeway from Cape Breton. The project will help manage vehicle queues that form when the swing bridge is opened. This map shows the proposed design for the new roundabout.


Entering the new roundabout will be similar to entering the existing rotary, but vehicles entering the roundabout must yield to vehicles already in the circle.

A bypass lane will allow vehicles coming from the Canso Causeway to turn onto Trunk 4 without entering the roundabout. Vehicles moving in all other directions will need to enter the roundabout.

The new roundabout is designed to improve safety by reducing vehicle speeds. It will also standardize operations to be consistent with other roundabouts in the province.

The new storage lane before the swing bridge will help limit the impact of vehicles queuing on the road when the swing bridge is open.

Careful planning and design measures and accepted construction techniques will minimize environmental impacts from road construction near developed areas and environmentally sensitive areas, and minimize disruption of highly erodible materials.

The cost to construct the new roundabout, intersections and storage lane is estimated at $5 million. This project is being funded by the Government of Nova Scotia through the 100-series highway safety improvement fund.

Project status

Planning and preliminary design work is underway for this project.

Construction of this project also requires completion of the detailed design of the associated roadways, acquisition of land and completion of environmental mitigation plans.

Construction is expected to start in summer 2021, ending in 2022. Night construction is anticipated to minimize disruptions to traffic during construction.
