Major Traffic Disruptions Ahead for Lions Gate Bridge Construction

Drivers heading to Stanley Park and across the Lions Gate Bridge should prepare for significant traffic disruptions over the next six weeks. Starting on September 12, 2025, and continuing until October 21, 2025, crews contracted by the Metro Vancouver Regional District will install a temporary overland water pipe as part of the extensive Stanley Park Water Supply Tunnel project. Daily construction activities will take place from 07:00 to 20:00, with potential night and weekend shifts.

This construction will lead to periodic lane closures at the intersection of Denman Street and West Georgia Street, specifically at the northwest corner of this critical junction. This area is located just east of where West Georgia Street meets the entrance to Stanley Park and the Stanley Park Causeway. The changes will affect the flow of vehicle traffic entering and exiting Stanley Park, causing delays that could extend to the Lions Gate Bridge.

Pedestrians will still have access to the area throughout the construction period. Emergency vehicles will also maintain full access to Stanley Park. At the end of each work shift, road configurations will be returned to normal. The regional district has assured that traffic control personnel, fencing, and signage will be in place to safely guide motorists, cyclists, and pedestrians through the affected zones.

Drivers are urged to plan for delays and explore alternate routes to minimize inconvenience. This project is part of a broader effort to upgrade critical infrastructure in the region. The new tunnel will replace three aging water mains built in the 1930s that currently cross Burrard Inlet at the First Narrows, serving as a vital connection between the North Shore’s reservoirs and water treatment facilities and the city of Vancouver.

The new 1.4-kilometre tunnel is designed to enhance the seismic resilience, capacity, and reliability of the region’s drinking water system. This upgrade ensures that Metro Vancouver can continue to provide clean, safe drinking water to millions of residents during emergencies, such as earthquakes or other significant disruptions.

The construction process will employ advanced tunnelling methods beneath Stanley Park, with entry and exit shafts being established at three key locations: at the edge of Lost Lagoon near the Stanley Park Causeway, adjacent to the Stanley Park Service Yard parking lot, and near where Tunnel Trail meets Stanley Park Drive next to the seawall. These activities will also lead to traffic disruptions on portions of Stanley Park Drive over the coming years.

The installation of the temporary overland pipe is crucial for maintaining a consistent water supply during the construction transition. The total cost of the Stanley Park Water Supply Tunnel project amounts to $495 million. If the timeline proceeds as scheduled, the project is expected to be completed in 2029, with construction having initially commenced in November 2024.
