You mean the report released in 2015 that states it's not economically feasible to seismically retrofit them to current standards? I know the one.
The frequency of damaging earthquakes is also more often then you have stated. The fact that they have not been well maintained over the years makes me more than doubtful.
The columns are also spaced too far apart and some placed on fill. You cannot tell me that they know the composition of exactly what is under each individual columnwithout digging it out to check. All it takes is one to give to cause a major disruption. If only one column gave and sank in the wrong spot the sections of roadway that would fall could either take out the skytrain line, damage the other viaduct or block street access.
You pick and choose and fudge things too much. Also being reactive and shutting down proactive conversation is toxic and very poor planning.
And the sidewalks and lanes are too narrow, and the water runoff systems need to be rebuilt etc. They cost far more to maintain than a street at ground level. Poor use of tax dollars to maintain part of a nonexistent highway viaduct...
Yeah keep talking down to me.
