Saint John drivers need to prepare for major traffic changes on Highway 1. Gateway Operations and the New Brunswick Department of Transportation and Infrastructure begin paving and milling work on Monday, October 12, 2026. This construction brings several temporary ramp and lane closures to the city.

Exit 119 Interchange Closures

Crews will shut down specific ramps at the Exit 119 Interchange to allow for safe milling and paving. You will see detour signage in the area to guide you around the construction.

The project affects the following ramps:

• Westbound Off Ramp 119A from Route 1 to Bleury Street
• Westbound On Ramp from Catherwood Street, Fairville Boulevard, and Bleury Street to Route 1
• Eastbound Off Ramp 119A and B from Route 1 to Bleury Street

Additional Highway 1 and Harbour Bridge Impacts

Beyond the interchange, you will encounter alternating lane closures on eastbound Highway 1. Workers will restrict traffic between kilometers 118 and 121, shifting vehicles between the driving and passing lanes as paving progresses.

The construction also impacts the Harbour Bridge. The off ramp connecting the bridge to Chesley Drive will close completely from Tuesday, October 13 through Friday, October 16.

Plan Your Commute

The City of Saint John advises all motorists to allow for extra travel time. Pay close attention to posted detours and reduce your speed when driving through active construction zones. For real time updates and closure information, check the NB511 system.
