Route 15/Harrisville Boulevard Interchange

The Department of Transportation and Infrastructure is continuing work to widen the Route 15 underpass to four lanes and incorporate active transportation features for pedestrians, bicycles and other users. In 2018, work will include the construction of tear-drop shaped roundabouts at both ramp terminals to create what is commonly referred to as a “dogbone” interchange. This configuration will reduce conflict, queueing and delays.

In conjunction with the work at Harrisville Boulevard, the Department of Transportation and Infrastructure will also construct a new eastbound exit ramp from Route 15 to Industrial Street, Dieppe.

This project will improve safety and traffic flow. All users will benefit from the wider, four-lane underpass, reconfigured ramp terminals and newly incorporated active transportation facilities. These upgrades to one of the province’s busiest arterial highways will reduce greenhouse gas emissions resulting from congestion and enhance travel for all commuters.

This project is being funded jointly by the provincial and federal governments. The Government of New Brunswick has committed $8.1 million and the Government of Canada has committed $5.7 million. Work is anticipated to be complete in the fall of 2018.

Strategic investments in infrastructure are a key element of the multi-year New Brunswick Economic Growth Plan, government’s framework to grow the economy and create jobs.

The drawing below shows the configuration of the new interchange.

Important information for motorists

Motorists can expect significant congestion and delays in the vicinity of the interchange and on the surrounding street network.

Full ramp closures are necessary to allow work to be carried out within a single construction season, thereby reducing the overall duration of public inconvenience.

If possible, motorists are encouraged to avoid this area by seeking alternate routes, carpool, take public transit or work remotely.

During construction, traffic on the Harrisville Boulevard structure will be reduced to one lane in each direction, and the following interchange movements will be closed to all traffic:

Westbound off-ramp from Route 15 (left and right turns)
Eastbound off-ramp from Route 15 (left turns only)
Northbound left turn from Harrisville Boulevard on to Route 15 on-ramp (westbound)
Southbound left turn from Harrisville Boulevard on to Route 15 on-ramp (eastbound)

In addition, the right turn movement from the Route 15 eastbound off-ramp (toward Dieppe) is expected to be closed for a period of time midway through construction.

Maps 1-6 depict the closed movements, as well as available detour routes.

At some point during construction, it will also be necessary to close the Harrisville Boulevard structure to all traffic to allow for curing of the concrete deck. These closures will be scheduled to occur on two separate weekends. The Department of Transportation and Infrastructure will provide advanced notice of these closures once exact dates are confirmed.
