The Louis-Hippolyte_Lafontaine_Bridge-Tunnel should have had been designed to have 2 wide emergency lanes. Then by now, there could have easily been 4 lanes each way. Unlike backward Vancouver, which is on a peninsula, Montreal is on an island, so more bridges & tunnels are necessary. However, Greater Vancouver still doesn't have enough bridges for proper a proper network of express bus & HOV lanes.

There really should have been a bus & HOV bridge or tunnel there by now. Everything is still crammed into 3 lanes each way.
