https://dailyhive.com/vancouver/metro-vancouver-residents-shocked-e-scooter-rider-george-massey-tunnel Another fine example of inept BC planning. Have a tunnel so narrow, because there aren't any wide emergency lanes. Then eventually it could have been 3 lanes each way. However, there should have been a provision to have another tunnel next to it within a few decades. Unfortunately, that never happened by the 1990s.
At least there should have been a bus, train & bike bridge built next to it decades ago, but that would go against the BC bottleneck mentality.
https://www.highway99tunnel.ca The 8 lane Tunnel_Replacement Project is supposed to be open by 2030. That's only 60-70 years late. Unfortunatly, another parallel tunnel or bridge will eventually have to be built, because there is still a need to eventually have the Tsawwassen_ferry_terminal become connected to the Vancouver_International_Airport, Waterfront_station and the Horseshoe_Bay_ferry_terminal with rapid rail transit.
