On December 7, 2014, a significant rockslide occurred in the Seymour River Canyon approximately one kilometre north of Riverside Drive. This rockslide partially blocked the Seymour River and increased the water level upstream, flooding area trails and the Twin Bridge. For safety purposes, a number of trails were closed and the bridge was removed.

Metro Vancouver has been working collaboratively with your municipality, consultants and the community to re-establish the network of trails in the Lower Seymour Conservation Reserve (LSCR). We held two public meetings in 2015 and 2016. The public input collected were considered in project planning and design. We are currently reviewing final details for design and preparing for construction in summer 2017. Construction will consist of the following:
- a pedestrian bridge across the Seymour River,
- a vehicular bridge for maintenance/operations access at Riverside Drive,
- new staircase replacement on Baden-Powell Trail at Riverside Drive, and
- trail improvements in the LSCR.
Public Open House
Metro Vancouver held two public meetings in 2015 and 2016 to discuss options for building new trail connections, to collect input on the LSCR Trail Strategic Plan and LSCR programs, and to establish a long-range plan for a new pedestrian bridge across Seymour River in the Lower Seymour Conservation Reserve (LSCR).

New Pedestrian Bridge Replacement
After the removal of the Twin Bridge, Metro Vancouver reviewed options to re-establish the east/west connection and to find a viable location for the bridge replacement. This process involved taking into consideration environmental, financial and technical constraints. After investigating possible crossing locations, Metro Vancouver staff have narrowed the focus to an area just south of the original Twin Bridge location.

Vehicular Bridge for Maintenance/Operations Access
The Twin Bridge was a popular connection for trail users and was the only vehicular access for Metro Vancouver maintenance staff. With its removal, we are planning to construct a new access path/bridge at Riverside Drive to re-establish an east/west connection for maintenance vehicles and to ensure that crews are able to access existing infrastructure.
New Trail Connections and Upgrades
In response to the rockslide, Metro Vancouver closed these impacted trails:
- Section of Fisherman’s Trail
- Bottle Top Trail
To ensure that trail networks continue to be safe and accessible, new trail connections and upgrades being considered include:
- A new trail to connect Powerline Trail and Twin Bridge Trail
- A new section to replace the closed section of Fisherman’s Trail
- Trail improvements for possible Bottle Top trail reopening

Fish and Environment
Metro Vancouver is working the District of North Vancouver, the Department of Fisheries and Oceans, and the Seymour Salmonid Society to ensure that any new improvements are implemented to the highest environmental standard.
