Halifax Harbour Bridge Closures & Commuter Detour Guide: Macdonald Bridge Closure Details & Bypass Routes

Commuters and weekend travelers crossing Halifax Harbour between Halifax and Dartmouth face major traffic delays following critical infrastructure closures. Official updates from Halifax Harbour Bridges and the Government of Nova Scotia confirm a complete weekend shutdown of the Angus L. Macdonald Bridge from Friday evening, October 2, through early Monday morning, October 5, 2026. Coupled with ongoing ramp construction on the A. Murray MacKay Bridge, regional transportation authorities urge motorists to utilize recommended driving bypasses or opt for municipal ferry alternatives.

Angus L. Macdonald Bridge Total Weekend Closure Details

The Angus L. Macdonald Bridge will lock its gates to all vehicular traffic, pedestrian lanes, and cycling paths throughout the maintenance window. Engineers require full access to the structure under Project LifeSpan, a multi-phase infrastructure longevity program.

These passes enable travelers to cross Halifax Harbour using cross-harbour bus lines detoured over the MacKay Bridge.

A. Murray MacKay Bridge Bottlenecks & Ramp Construction

With all cross-harbour vehicular traffic diverted to the A. Murray MacKay Bridge, drivers face secondary gridlock on the Halifax side of the harbour.

The Massachusetts Avenue ramp connecting the MacKay Bridge directly to Robie Street and Barrington Street remains closed for road construction. Traffic exiting the bridge onto urban streets encounters severe bottlenecks. Municipal traffic management teams will manually and automatically adjust signal timing across key intersections to mitigate gridlock, but travel times across all Halifax-Dartmouth corridors will be significantly prolonged.

Recommended Driving Bypass Routes for Motorists

Traffic engineers have laid out specific bypass routes to help drivers navigate around the Massachusetts Avenue off-ramp closure on the Halifax shoreline:

RECOMMENDED DRIVING BYPASS ROUTES IN HALIFAX

Category / Entity	Details / Impact
Destination Corridor	Recommended Bypass Route & Navigation Instructions
West End & South End	Turn onto Windsor Street immediately after crossing the MacKay Bridge.
	Completely bypasses the closed Massachusetts Avenue ramp.
Central Robie Street Corridor	Divert down Kempt Road and connect directly onto Young Street.
	Circumvents main bottleneck into North End and central commercial districts.
Waterfront & Downtown Halifax Core	Take the lower Barrington Street exit ramps.
	Avoids upper ramp delays and provides direct line into downtown core.

Public Transit and Marine Ferry Alternatives

Travelers seeking to avoid vehicular gridlock altogether are strongly advised to use public marine transit operated by Halifax Transit. Ferries provide an uninterrupted cross-harbour link completely unaffected by bridge roadwork.

└───────────────────────────────────────────────────────────────────────────────────┘

• Bus Transit Detours: All cross-harbour municipal bus routes normally using the Macdonald Bridge are rerouted over the MacKay Bridge. Passengers should anticipate delays and check Halifax Transit schedule updates.
