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

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 and right turns)
  • 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)

The Department of Transportation and Infrastructure advises the travelling public that work on Harrisville Boulevard will cause an extension to the full closure of the bridge spanning over Route 15. The full closure will be in effect until mid to late October, weather permitting.

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

 Traffic advisory

The Department of Transportation and Infrastructure advises the travelling public that work on Harrisville Boulevard will cause an extension to the full closure of the bridge spanning over Route 15. The full closure will be in effect until mid to late October, weather permitting.

The closure is required for safety reasons and to expedite the work at the Harrisville Boulevard interchange due to the tight work area and the upcoming cold weather. Detour signage is in place to direct traffic around the closure.
