I have had to do that maneuver a lot of times when working downtown (P&R) or going to the mall.... Once I had to honk as me and another driver tried to merge into each other's lanes, but otherwise it's OK (although certainly adds to your stress). The biggest problem I had was drivers coming from Orleans and getting off at St. Laurent would sometimes be going a lot faster than drivers on the three through lanes, and would sometimes pass merging drivers on the shoulder... or people would drive fast all the way up to the off-ramp and squeeze back onto the highway at the last second.
The rerouting to Aviation will certainly be safer, but I will miss the off-ramp with the bridge that takes you right to the mall
