Boundary Bay Wildlife Management Area protects a vast stretch of intertidal mudflats, salt marsh, and eelgrass habitat along Boundary Bay. The area supports large numbers of migratory shorebirds and waterfowl, making it one of the most important bird habitats on Canada’s Pacific coast. Its accessible trails, consistent bird activity, and ever-changing tidal scenery make it an especially rewarding place to explore on foot or by bike.

On the east side of the bridge’s northern end, near the base of the bridge is a memorial to honor 27 workers who lost their lives on June 17, 1958, when a section of the original Second Narrows Bridge collapsed during construction.

The Seymour River Suspension Bridge was completed and opened in December 2018. This made it possible to walk the Fisherman's Trail (North) all the way through again. After the former Twin Bridges had to be demolished in 2014 following a rockslide and damming of the Seymour River, there was no longer a crossing at this point in the Lower Seymour Conservation Reserve. The Twin Bridges were originally built in 1908 to carry pipelines and were later supplemented by a parallel pedestrian bridge. Years later, the two bridges were combined to form one bridge. https://www.vancouvertrails.com/blog/seymour-river-suspension-bridge/

The Pipeline Bridge is a pedestrian bridge over Lynn Creek, offering views of the creek in the gorge. The bridge was built in 1993 and serves as one of the park entrances to Lynn Canyon Park and Rice Lake in the Lower Seymour Conservation Reserve. The bridge was built over existing pipelines. A few meters upstream is the Old Pipe Bridge, which is not open to the public.
