In the 1930s, NW was still a former tiny BC capital and an ongoing provincial backwater. It was amazing just to have plumbing and electricity in parts of Surrey. No one thought in the 1930s that Surrey could eventually become a major city, at least by BC standards. Then by the 2030s, becoming the biggest populated city in B.C.
Unfortunately, the Pattullo Bridge and its replacement weren't designed to accommodate 2 streetcar tracks or 2 LRT tracks. Both bridges opened with just 2 lanes each way. The 4 lane Pattullo Bridge should have been designed to have 2 very wide shoulders and 2 wide sidewalks so that it could have become a 6 lane crossing with a proper safety divider for traffic.
While the replacement bridge is also just 4 lanes, there is a 6 lane potential in the design. However, the new bridge should have opened with 3 lanes each way, plus a 4th lane for express busses. Then, a 5th lane could have been a very wide shoulder, or an outright emergency lane.
Instead, when either 4 lane bridge has a stalled vehicle, the 2 lanes become a 1 lane chokepoint. If there is an accident on 1 side of the bridge and a stalled vehicle on the other side, 3-4 of the lanes can instantly become blocked.
The old and the new bridges weren't designed to have a lower deck for 2 tracks and 2 truck lanes, even though its part of a major seaport region.
In contrast, the 1932 Sydney_Harbour_Bridge opened with 6 lanes and 4 tracks. Then, in the late 1950s, two tram tracks were removed, thus allowing for the Sydney_Harbour_Bridge to become an 8 lane crossing. This was possible, because NSW wasn't thwarted by anything like a provincial backwater BC mindset, or the BCMV.
