The Lions Gate Bridge crosses the Burrard Inlet to link Vancouver with North Vancouver. It is named after The Lions, a pair of mountain peaks that are part of the North Shore Mountains.
The bridge originally opened in 1938, and was funded by the Guinness family, before being sold to the province in 1955. The bridge has been widened and increased from two lanes to three, but still remains a significant bottleneck during busy periods.
